Title: R9 280x flashed with EFI
Post by: blacksheep on October 31, 2013, 03:47:20 PM
Current batch of R9 280x (Tahiti XT2) is rebagded 7970 GHz edition, so it wasn't a big surprise that it works in OS X and it's flashable as well. AMD didn't even give it new device ID. It's reserved for upcoming Tahiti XTL, I think. So, new name, same chip and specs as its predecessor but much better pricing, at least.

Mine is OC edition with factory clocks 1100/6000 - like 7970 GHz edition. And its performance is almost identical. Currently both are fastest single GPU AMD cards, until 290 and 290x will come to the market.
Some benchies below. If you want to see how your card is performing against this one, you should use my settings in Heaven and Valley.
In Mavericks it kicks butt in OpenCL (last screenshot), ofc in D700 clothes ;)

Edit: added Furmark scores

Nice work !!! Did you give it the name "R9 280x" or did that just show up?

Very nice numbers for 7970, looks like the improved clocks sped things up.

Nice to see someone take initiative.

Thanks. I really appreciate that.
I had to give it name manually in EFI, drivers recognize it OOTB as 7xxx before flashing.
I bought OC edition, reference clock is 1000 IIRC, where 7970 GHz ed. is 1050. Mine has 1100.
Actually I was a bit disappointed with performance, I hoped for slightly better bump. My (heavily) OC'ed 7950 is almost on par with this particular 280x, at least in OpenGL.
But for that price (about $100 less than 7970 GHz) it's still very good.
My main concern was real power usage under heavy load. iStat, which I use now, reads max 8A on PCIe Booster.
In Furmark with 7950 it shows 7.99A from both boosters and 4A from the slot.
I'm waiting for Hardware Monitor license, it seems to be a better tool.

I'm not sure my Current sensors are working ok on my machine with my 7950.

PCI-E Slot: 45W
Boost A: 90W
Boost B: 55W.

200W for a overclocked 7950 with Furmark is reasonable and if I swap the boost wires then the values swap.

Without getting an actual Ammeter in there I could not determine if the values are correct or not!

Post by: Rominator on November 12, 2013, 05:38:35 AM
yeah, it's funny, but seems 100Watts on a single cable works

That being said, I have twice in last 24 hours had a Titan take my 4,1 DOWN

Oddly enough it was the same app that was aproblem years back with a 4870x2...good old Crysis. (Warhead version)

I wanted to see it on 4K display at 60 HZ. Saw a few minutes, then I jump and when I hit the ground...click...nothing.

And it isn't just a bad Titan, two different cards, same thing.

So there is an app that can make Titan go past power limits. I wuld be frightened to see what that number is as I have seen steady 130-140 readings in Hardware Monitor with no crashes.

And that also means that 780Ti is MOST DEFINITELY external only.

And to avoid being a complete thread jacking a--hole, Blacksheep I have seen you state elsewhere that R9 290x doesn't work yet in OSX.

Does that mean you tried?

I didn't try, but I was looking for device IDs of 290 and 290x in drivers and didn't find them. Only Hawaii Pro and XT descriptions in AMDRadeonX4000 kexts.
This would indicate that support for Hawaii is coming, but it isn't already here, perhaps in future drivers update.

I tried a R9 290 on a Mac Pro 3,1 and can confirm it does not work (10.8.x or 10.9).  (Works great in Boot Camp, of course.)

Looks like the 280x is the best AMD card for my machine ATM.

Hi blacksheep,

What card do you have exactly?
GV-R928XOC-3GD (rev. 1.0)
http://www.gigabyte.com.au/products/product-page.aspx?pid=4793#ov

or

GV-R928XOC-3GD (rev. 2.0)
http://www.gigabyte.com.au/products/product-page.aspx?pid=4845#ov

What ROM file did you use?
Do you follow up on getting more accurate power use data?
Will it be ok using Mac Pro 4,1 internal PSU?
Thanks

Seconding this, I'm curious if this card can be run without the need for an external PSU.

Yes, it does run on internal-only all the time.

@blacksheep:

Nice work indeed!

Forgive me if this is already answered, but I saw someone above asking if you enabled PCIe 2.0, any news on that?

Also MSI just announced a 6GB vram version of the R9 280X with 2 6pin Power Connectors, would love to see what you geniuses over here at Netkas would do with that one.

XFX 270X flashed to 7xxx EFI.  Lists as a 7950 because I don't know how to change how it displays (does it matter?).  Shows up in system profiler.  Has boot screen.  No HDMI output, everything else works fine.  2.5 GT/s for now.  Anyone now if this card can go to 5 GT/s?

No HDMI output, everything else works fine.
DVI doesn't work too, if I recall? So out of 5 ports only 2 do work, correct? XFX one isn't a perfect candidate for flashing, there are better ones on the market.


Title: Re: R9 280x flashed with EFI
Post by: jasonsansone on January 10, 2014, 05:17:11 PM
Correct.  Only two mini display port work, but that is all I needed and it was cheap, so it works.  However, I agree it is a poor candidate for most.

Looking to put an R9 280x in a 3,1. Need it for OpenCL and GL in Mavericks and for Boot Camp to Win7.

Would like to just use internal power, and i need 2 x DVI (with one of them being dual link)

Can anyone advise me which makes/models would be my best bets (5GT/s without any soldering etc) and how the EFI flash is done?

Thanks in advance


Title: Re: R9 280x flashed with EFI
Post by: MacVick on March 16, 2014, 07:22:10 PM
I just bought a XFX Black addition R9 280x from newegg, to put in my 2009 Mac Pro 2.93 8 core. I am waiting for a 8 to 6 pin adapter from
amazon which should come in tomorrow as you can't connect this to work with the stock cables that it comes with in the box.
I am hoping the duel link DVI port works as I want this to connect to my 30 inch apple monitor.
Rob at Barefeats said it worked unflashed for him with the 8 to 6 pin and 6 pins, but I think he was testing it with a 27 apple monitor via mini display port.
I also have a duel link mini display port adapter but when I tried it with my current 5870 the 30 inch display I would get some green dancing pixels on the screen.
Using the duel link DVI connection with the same 5870 works fine.
I will report back on here when I get the adapter cable and see if it works or not and what ports are working.
I would like to flash it down the road but have never done it before so if anyone can point me to a good link on that it would be appreciated.
Does flashing it give you PCIe 2 speeds or just the boot screen? and if so how do you get PCIe 2  speeds.



from barefeats: " The Radeon R9 280X we used was 'un-flashed.' It booted OS X fine but there was no startup screen. Also, when we checked the speed of CPU-to-PCIe-to-CPU communication, it appeared to be running in PCIe 1.0 mode instead of PCIe 2.0. However, unless the GPU intensive app saturates the PCIe 1.0 bandwidth, it will not run any faster in PCIe 2.0 mode."

Rob also said that he only got slightly faster speeds with the card when flashed.

Wait? You got a 270x flashed and working? Doesn't that mean it should work on 270 (non x), too?
That would be so awesome for dual gnu ...

The 270X is just a rebranded 7xxx series card, so we have EFI for it to flash.  I thought the 270 was actually a new card, not a rebrand Tahiti series.

Post by: electonic on March 17, 2014, 12:07:13 PM
I'm really confused now. All the review sites say 270x and 270 both are Pitcairn.
But 270 really is another architecture, isn't it? Because of this confusion – thanks Anandtech, etc ;) – I keep coming back asking these stupid questions.

I had another idea: judging from the specs the 270x is just barely over 150 Watts.
Do you guys think it would be worth a try to under clock a 270x with a modified BIOS and try to get them to run with just one 6 pin connector, or does something like this not work at all in general?

I'm still trying to find a good dual GPU for my Mac Pro on internal power and 2 x 7770 is just a little too weak, I think.  Two down clocked 270x with 1 x 6 pin and EFI would be a great deal better ...

What do you think? Should I order one and try, or is that out of the question?

Could use some help please ???,,, and I am new on this forum.
Just tried to install an XFX R9 280x black addition into my 2009 mac pro, still have an older 1600xt installed in pcie slot 2 the 280x is in slot one. Using a 8 to 6pin adapter
and 6 pin to  6pin. I get my boot screen, but after the Apple shows up on the
monitor connected to the 1600xt, that's as far as it gets and the login screen does not appear and the fans spin up just a bit.
The fans are spinning on the 280x, but there is no signal to the monitor that's connected to the 280x and I tried both DVI and MDP.
Maybe its a bad card? or maybe it just isn't going to work. I reinstalled my 5870 and all is fine. But kinda bummed I thought it would work.
Maybe its this version of the card.
Any help would be much appreciated.

Oops sorry it's the 2600xt.

I have OS 10.9.2 and 10.8.3 as I go back and forth between the two. But have been trying the card under
10.9.2.
The card came with one 8 to duel 6 pin and one 6 to 6. I bought a 8 to 6 adapter on amazon as Rob from bare feats said he used that and the 6 to 6. The card does not show up under system report pcie slots. Should I be using just the one eight pin that came with the card to both six pin on the board?
Thanks for getting back.

I have tried just about everything and the card just never shows up in the system report let alone display any video signal. I guess it must be a bad card.
Not sure if I should return it for the same card or try a different version. Its the XFX Black double D version. Any other ideas would be great before I return it
for another. ???  :-\


Title: Re: R9 280x flashed with EFI

Does the 6 to 8 have a single 6 in to the 8 or is it dual 6 into 8?

The dual 6 into 8 only work when 6 is plugged into side with fewer wires.

Armdn, if you take the 7970 EFI and add it to your PC BIOS then your card isn't downclocked.

Please explain what you are trying to say, what us this about SSID ?


Title: Re: R9 280x flashed with EFI

I have two variations the one that came with the card is 8 pin to duel 6pin
and one I got on amazon 8 pin to single 6pin.
I have tried both in conjunction with a 6 pin to 6pin.
All my pcie slots are full.
slot 2 has 2600xt
slot 3 pro tools native
slot 4 OWC accelsior 2

maybe the card just cant get enough power. Not sure what you mean by exactly by

"The dual 6 into 8 only work when 6 is plugged into side with fewer wires."
Not sure what you mean exactly.

Post by: MacVick on March 19, 2014, 02:26:45 AM
Both six pin connectors have six wires that lead into the 8 pin connector but they are wired differently to the 8 pin.
Using the one with the less spread out wires the mac pro boots, still the 280x does not work though or show up under pcie slot in system profiler. Using the more spread out six pin
of the duel 6 to 8 it freezes after the apple right before log in would be and the fans spin up a bit and then Ihave to force shutdown. A member on apple discussions advised me to get a duel esata to six pin cable and use two of my internal
drive bays to power the six pin on the card with that and use the eight to six off the mother board.
Do you think that would work...? If that doesn't work then I guess I gotta return it. Not really happy about loosing two drive bays to power the card though but its most likely safer for the mac power wise
and of course it still might not work and just be a bad card. Ugh!  

here is the cable that I might get.

As i say earlier, i done that already. Mixed my rom with your efi part. But, i renamed the card in efi part, as R9-280X but, my rom has a different SSID: 2770, and no matter what, my card recognized as 7970 now, but netkas's efi makes it recognized as 7950. All DeviceIDs correct. But now, i changed SSIDs to 00b0 in both parts of rom, and now it shows up as R9 280X.

Great news.

But I'm not sure I follow where you found SSID in two places.

Also, when you say it shows up as R9 280X, do you mean in System Profiler or OpenGl view or where exactly?

Could you post your rom and some screen shots?

Drag about this board is attachments are limited to 250K each so I frequently have to shrink size down in Photoshop when I use Apple screen shots.

Hey MacVick and Rominator,

I am trying to get an XFX R280X working in my machine also. The Double D edition - not black.

I have the exact same symptoms you have - loads to apple icon just before login screen and locks up.

I also have the same mini mac 6 to 8 ping cable and mini 6 to 6 pin cable.

If I boot into safe mode, the machine does see the card as an ATI card, but its not actually loaded in any way.

Does anyone have any ideas of things that I could try in order to troubleshoot this? All help is appreciated.

Cheers

http://www.amazon.com/gp/product/B002UOFDO2/ref=oh_details_o01_s00_i01?ie=UTF8&psc=1

What other option do I have for power? I have seen many other posts in this forum and others in getting the 7950/280x cards working, what sort of cables do they use?

Hey Robicharters,
nice to see someone with the same issue, sorry you are having it as well, but hopefully we can figure this out.
One thing you might want to try seeing it did show up in your system profiler is zapping the pram. I am going to try that today.
I ordered one more cable from newegg, that goes from two esata ports to one 6 pin on the card
and will use the original 8 to duel 6 that came with the card to go into the 8 on the card to the two 6 pin ports on the logic board. NOt sure if that will really help or not.
The new cable wont be in for a few days.
Rob at barefeats says he got his working non flashed with one 8 to 6 and a 6 to 6, it was a different brand 280x though and the DVI and MDP worked but not the HDMI.
I also went for the flashing service which macvidcards just started to offer on ebay

http://www.ebay.com/itm/231184414452?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

, but I want to make sure the card works before I send it to him.
I am hoping to here back from him about the power issue, any thing I find out I will post here, please do the same.
cheers.

If you use 10.9.2 then you can't use an I flashed card with MDP.

In 10.9.3 you need to use left MDP

If you use a dual 6 into one 8 you need to use the 6 side that has fewer wires.

I don't get what you are saying about the duel 6 to one 8 cable. Each 6 connector has six wires running to the 8. 12 wires total.
There is not one with less wires than the other at least not with the XFX cards. Am I missing something?

 MY card has two MDP one HDMI and two DVI.

Update

Card works great in windows bootcamp with latest catalyst drivers.
There seems to be no problem with the power cables while running in windows, is there a difference there running for OSX?

Have tried booting in 10.9, 10.9.1 and 10.9.2 and all hang before login screen.

Would flashing the card make any difference? Let me know what the LA MacVidCards says.

So it's not a power issue?? I don't have a bootcamp partition at the moment, I use  VMware fusion.
No word from macvidcards yet. I wrote them twice and ordered the flashing two days ago.
Weird that I have not even gotten an email about where to ship the card.  Maybe paypal payment has to be
cleared first.

Well I guess I bought the wrong cable, mine is definitely  wired differently.
Thanks 3mvideo.

Here is the same one from a different vendor but says its for a Mac Pro not G5, same photo of cable.

I'm not going to buy any more cables and hope to hear back from macvidcards. I am guessing he will supply the cables with the
mod / flash service.

Post by: robincharters on March 21, 2014, 06:21:51 PM
I think I may have found the problem.

It seems that R280x's have been silently upgraded by vendors in new cards with Tahiti XTL vs the older XT2.

Looking at the BIOS in Windows confirms that my card has the XTL chipset in it.

Now the question is - will this card ever work in OSX?

Does that mean it's working at pcie 2.0  non flashed in 10.9.3?
Also I am guessing this card will not work at all in MT Lion unflashed or flashed, which is an issue for me as I still work in
MT Lion for the most part when it comes to my pro tools rig. Please advise.
I only care about one working DVI port for now.

I don't think your 280X is going to work in your MacPro. Like mine, if recently bought, it has probably got a Tahiti XTL chip in it, rather than the older XT2's that AMD was putting in the 280x which made them essentially 7970's. Recently they have been putting XTLs in the 280x, which is probably the reason we can't get our XFX R280x's to boot on the mac.

I have decided to return mine, and get a 7970 off of craigslist or ebay.

Correct me if I am wrong.

Xfx r9 280x working fine here

Can't emphasize enough about MDP causing crashes on NON flashed cards.

Also IF your dual 6 to 8 has fewer wires on one port 6 pin connector, you must use that side.

Rominator... please help with a bit more info or a photo of your cable would be really helpful.
I posted my duel 6s to 8 on page 3 but you did not comment. It has 12 wires leaving the 8pin and each 6 pin connector has 6 wires going to them so there is not one with less wires.
Are you using XFXs cables that shipped with the card? The duel 6s to 8 and the other 6 to 6.

Any extra facts would be really appreciated.
Thanks!

Rominator (and the rest of the gang) - Following up on my MSI 3GB R9-280X.  A few questions here, as I'm still stuck in 10.9.1 for the moment.

1) I need to use both MDP ports, for a dual display setup for FCPX. Would both ports be useable in 10.9.2 if it was flashed?
2) Is the MSI card actually flashable? Just a little clueless as I haven't flashed a card in 5+ years...and I figure there's a master BIOS image that's compatible to this card...

Thanks!

You're wrong. Both chips do work.

Ok, so my problem is related to power then?
Does anyone else have a Tahiti XTL R280x working in their machine?

What do I need to do in order to get the correct power into the cards.

The machine runs the card in windows perfectly fine the way it is now.

My tower is a 4,1 with 5,1 MB flash - could that be part of the issue at all?

Pictures are welcome

Title: Re: R9 280x flashed with EFI
Post by: Rominator on March 23, 2014, 12:51:36 AM
Had a look at the dual 6 to 8 that comes in XFX box.

If you trace the wires, the side that tracks to an "L" shape is side to use for testing.

But if it boots and runs in Windows then it isn't power, the part of rom that halts boot for power sense is part of BIOS.

Once flashed, I don't believe any of these cards will have HDMI.

10.9.1 is last trouble free OS version.

I am going to discuss with Netkas making a sticky at top. We keep getting identical questions over and over and ideally you all could save us a lot of time.

10.9.2 intros the "must be flashed or MDP crashes boot" issue and so far 10.9.3 has even weirder ones related to MDP.

It is vital if people want help with GPUs that they post:

1. which exact card, ideally not just part number but also BIOS number. If you look in first 2K of rom there is frequently a RAM vendor listed like "Hynix" or "Elpida"
2. Need to know which OS. If a beta, we need to know which build.
3. If it has any 8 pins, we need to know how you are connecting. Many dual 6 to 8 adapters will NOT work if only use from one side. The other side frequently will work but isn't a good long term solution. If you use an external power supply, how are you triggering? The PSUs don't have ESP and frequently need a line to go 12v + or pin to get grounded to turn on. Don't make us ask you, best if you take a pic and attach. You may have to use PS or some other image processing app to crunch it below 250K.
4. Absolutely CRUCIAL that you tell us what display and how you are connecting. A Dell u2410 has 4 or 5 ways to connect. So, you need to say "I have a Dell U2410 and I am trying to connect from MDP out of card to VGA in on the Dell using a Startech Z1000 adapter". We need to know this, why make us a ask?
5. AMD cards right now are far more likely to have port issues related to OS, port type, personality used, etc. tell us these things, DONT MAKE US ASK, please.

Thanks for all the info Rominator, also I apologize for my redundant questions...

I gave it another shot today using the L shape of the of the duel 6 to 8 connector and a 6 to 6 which I had tried before but under 10.9.2,
I booted under 10.9.1 this time but it still chokes at the login area of the boot, I had auto login on.
I was connected via the DVI port to a Acer 22 inch 1080 monitor to the bottom black dvi port.

Hi Rominator and Blacksheep (and the rest of the gang online here),

Okay – I went back and spent a few hours studying the posts on the forum, and I think I'm ready to go. However, I want to check back with you guys before proceeding.

Requested Info:

Card: MSI R9-280x 3GB GAMING
http://www.msi.com/product/vga/R9_280X_GAMING_3G.html#overview
Mac: Genuine 2009 MacPro 4,1 with the 5,1 firmware upgrade
BIOS #: 015.042.000.003
OS: OSX v10.9.1 (10.9.2 was loop of death with dual 27” Apple Cinema Displays)
Pins: One 6-6 mini PCIe, One 6-6 mini PCIe with the 6-8 pin adapter; connected directly to motherboard. Runs fine unflashed in 10.9.1.
Displays: Two 27” Apple Cinema Displays, connected to both MDP on card.


1) Today, I set up BootCamp on my Mac on a separate drive, running Windows 8.1.  Downloaded and installed GPU-Z to dump the ROM, which was listed as “Tahiti.rom”.  Apparently, it’s the latest version for MSI, so I’m not updating it before adding the EFI.  Also installed ATI_Winflash, for when I’m ready to go.

2) Back on the Mac-side of things, I made sure to install Java and Python.  The flashing folder is at my root directory, and is ready for the script. Apparently, my device id is 6798. 

3) I have also installed HexEdit.  Which file will I edit to change the parameters for it to have it correctly show up in my system preferences? (R9-280x? 7970?) Do I use HexEdit to edit my original ROM?  If so, there was no 79xx string to change, from what I could see.

3) **** Here’s the kicker:  I spent quite a bit of time on the forum to try and find the correct EFI file for the 7970. I have the “7950mac.efi” file, but couldn’t find it’s 7970 counterpart.  The only thing I could find was “MAC7970.ROM”, which I finally found...but I doubt it’s the correct file; I’m guessing I need “7970mac.efi”. (Maybe there could be a sticky somewhere for people to find the correct files?)

4) After running the script, I will go back to Windows and run ATI_Winflash with the new file and will reboot (keeping my fingers crossed).

5) I’m fully aware about removing R17 for PCI 2.0 on the original 7950 and 7970 cards...Does this also apply for the R9-280x?  Attached is a photo of the backside...I’ve drawn a red rectangle around R17...which runs right through R18. If this correct, I’m assuming that using a low-powered soldering iron and touching the surface-mounted resistor back-and-forth should allow for easy extraction, correct?  Definitely want to double-check on this one as this didn’t seem clear in the forums for the R9-280x.

Again, I hope I’ve been diligent in doing my homework but I figure it can’t hurt to “measure twice and cut once” before proceeding.  Given that I’m using my Mac for daily work stuff, I want to make triple-sure things go smoothly before proceeding.

Many thanks to all you guys for all your help...especially netkas, rominator and blacksheep.  Cheers!

Open the 7970 Mac file in a Hexeditor.

At 65536 you will find the EFI part.

Copy and paste into your R9 280X at same point, overwriting the UEFI, done.

About the R17:

Looks like your 280x shares this board layout from 7970/7950.

R9 280x rebadged 7970 cards.

Post by: thoomp on March 25, 2014, 03:02:54 AM
@rominator - Many thanks. Did the cut-and-paste method in HexEdit and all is well; no script necessary. Now I'm just tempted to go back and make it read R9-280x. Thanks for all your hard work on this forum!

@electonic - Thanks for the photo you posted. Yes, it seemed like this MSI version the same...so I just went ahead and got rid of R17 and it rebooted just fine. (Just wonder where the resistor flew off to...as I thought I had it)

About thirty years ago, I used to do HexEdit type editing on an old Apple IIe...and it's amazing that in 2014 I'm using it once again for something ridiculously more powerful.

Confirmed working as rebooted into OSX v10.9.1 with both MDP screens.
Ran upgrade to OSX 10.9.2 without a hitch.

Thanks again for everyone's help!

@thoomp: Great work man!

If you have a moment I'm sure folks here would love to see any screenshots of benchmarks, and perhaps a screenshot of your System Information PCIe info showing 5.0 GT/s from the R17 resistor removal.

Cheers + thanks again for sharing your experiences.

PS: Anyone know if this ROM would work for the same MSI R9 280X Gaming card running 6GB RAM or would it need to be updated to utilize the additional 3GB of RAM on the card?


Title: Re: R9 280x flashed with EFI
Post by: thoomp on March 25, 2014, 02:27:41 PM
Hey stmp - Thanks!  (And again...a huge thanks to the rest of the gang here who were brave enough to tinker around with this in the first place.)  I hope that my posting will help others just as others have given me a hand here.

I ran Heaven, but it looks like the difference with the R17 removal was negligible as expected. An extra 5 FPS (a score bump of 2423 to 2557), as you can see, but I'll take it for 5 minutes with a loupe and a steady hand.

I'm a little uneasy that I lost the R17 resistor for any issues down the road, but it's running great for what I want to do and it hasn't blown up yet. ;)

However, I like that it actually shows up now as a 7970 instead of 7xxx. (If I have time, I may go back in HexEdit and reflash to have it show as R9-280x...but I'm the only one who would ever care about that cosmetic detail.)

I'm just glad that I have a Mac that runs stably in 10.9.2 with two MDP ports, boots with the Mac screen, and renders quickly in FCPX -- as I rely on this for work.  After a horrible downgrade to 10.9.1 with the unflashed card, it's really great that things seem to be resolved.

Ah, my English completely turned around what I wanted to say again :D

I wanted to say that, if it already shows a difference of 6-7% in a game benchmark, there will be a noticeable difference in Pro Apps / OpenCL Apps, too, I suppose. If you have the time, you could do the BruceX FCPX Benchmark. Remember to export to ProRes422, if you do it ;)

Have fun with you pimped cMP. Had a 4,1 once, upgraded from Quad to Six Core xeon and modded 5870 and flashed to 5,1 :D
Now I'm on a legit 12c with 680 gtx ... flashed again :D Can't break the habit, I guess.

Post by: Rominator on April 01, 2014, 07:52:26 PM
So, the guy posting that his r9 280x wasn't booting into OSX was right.

He sent it to me for an EFI and I can confirm that the cards original rom would NOT allow booting into OSX.

Tried on 3,1 and 4,1 screen stayed black. Using single slot EFI GT640 I saw boot stop as long as 280x was in.

Looked at rom in VBE and it has 4 power states that are defined differently then mac 7950 ones.

The really freaky thing is I got 2 of the same cards a week or two ago and they worked fine as both self Init  and once EFI. Their power states were more like Mac 7950.

So, I am sadly reminded of 4870 days when XFX went so far from reference that the ZWFC variants were useless to flash.

I have been able to use parts of older 7970 roms to get the card functional but lesson needs to be learned.

If you have powered properly and it won't auto unit but boots into Windows fine, you may have an incompatable rom.

Hey guys,

today i flashed my 280X with EFI rom build with the netkas script and the card show up in OS X as 79xx.
What do I need to edit to have it recognized as R9 280X?

And another question, is the power that 280X get from Logic board enough for this card? I am using 6pin to 8pin adapter (single) and another 6pin direct connected to 280X. Or do I need dual pin6 to pin8 adaptor and an SATA power to 6pin adaptor?

Thank you for your help

Using the 7970 EFI I posted, it should show up as 7970

If not, it isn't using EFI

Don't use 7950 EFI on a R9 280x, it has same device id as 7970, so use that

And really guys, you don't need a script.

Just a hex editor and a brain

I used HexEditor in Windows, and bios position whre I should start to copy EFI (65536) was not the same as where to paste in original file, and file was different size. so I tried script. Now back on Mac I copy/past'ed and everything seems to be ok (also same file size).

How about power? do I need necessary additional power from SATA ports? or is just a 6pin to 8pin adapter ok?

Don't use 7950 EFI on a R9 280x, it has same device id as 7970, so use that
...

Flashed with EFI copy/pasted to my original bios rom. Now card is detected as 7970. but how I can change it to show 280X?

Sorry if I asking stupid questions, but I I dont ask I never learn :) I tried to find anything here in forum, but only saw I need to change something (SSID or something like this) but didn't found what exactly

If you are referring to aims made by armdn, if you peruse his later posts he admits he never actually got card to show up as R9.

In any case, it will probably always show up as "Tahiti Protytpe" unless you can spoof it into being a D700.

All 3 share same device id.

SSID may hold the key but Apple has included some jiggery pokkery to keep "D700" from showing up as it did before 10.9.2

I saw some screenshots sowing R 280X cards (only in OS X "About this Mac" Info or System Report) so I assumed it's possible to change this only "cosmetic" part. I dont care if it shows up in Benchmarks as Tahiti Prototy or something else, as long it give me the performance. But since this not possible I will be happy also with 7970..

Would somebody please post Specviewperf 12 benchmark results for EFI flashed 280x? Preferably both in OS X and in Windows bootcamp mode.

The reason I'm asking is there were reports for "abnormally" high results of Specviewperf 12 in comparison with "stock" 280x ROM for some of the tests (especially SNX-02). If these reports are confirmed, then it would be possible to use 280x for CAD applications without performance hit.


Title: Major PITA for PR and AE users :(
Post by: blacksheep on April 21, 2014, 08:24:32 AM
I discovered recently that my new 280x doesn't work with AE and Premiere. Tried CS6 and CC - Premiere hangs on startup, AE crashes with GPUSniffer error code 3. In 10.8.5 and 10.9.3.
No matter what I've tried – it doesn't work. Flashed and unflashed, named as R9 and 7970, added to openCL_supported.txt and with the file removed... Always the same error.
280X isn't even on supported list for PR Win version.
Other Adobe programs (PS, AI, ID, ME, DW, FL etc.) work well, only these 2 don't want to. What left is to test CC in 10.9.3.

Would somebody please post Specviewperf 12 benchmark results for EFI flashed 280x? Preferably both in OS X

Link to OS X version (there's no such thing on their website)?

Update: same story with CC and 10.9.3
If anyone got 280X to work with PR or AE CS6/CC, please report how.

Update 2: R.e.s.o.l.v.e.d., see 2 posts below...

I can open both Premier and After Effects CS6 versions, I don't have any projects to really put them to the test but they launch fine no errors.
I have a flashed XFX R9 280x double D black addition. I do have other issues with games blacking out and the computer locks up after a few minutes and slow frame rates in heaven / valley. i bought a PSU because I think
think the card with its pre set overclocking may suck too much power when it goes into game mode. If I pre ramp my fan speeds up on the card then the card is stable in 10.9.2 still finky in 10.8.5 but frame rates are still slower than they should be compared to others. It also blacks out in Windows unless fans a pre ramped up to 2000rpm, I tried the Adobe apps out on 10.8.5 have not tried them in 10.9.2

Title: AE and PR problem resolved
Post by: blacksheep on April 21, 2014, 06:12:39 PM
I don't know how and why, but it wasn't my card... It was CUDA driver 5.5.47 :o Examined crash reports more closely and bingo!
Updated to 6 and problem is gone...
Weird shit... Few days ago I used AE and PR with CUDA 5.5.47 installed without a single hiccup, along with GTX 680 and GTX 570.
I think I'm getting old, because I have no idea what has changed during these few days. I didn't update my apps nor OS.

Have you had any overheat issues when trying games or Heaven? I have three monitors running one being apple 30 inch. Which is great, hoping external psu will solve the black out issue, if not may have to get something else. Does not black our when rendering FCPX.


Title: Re: R9 280x flashed with EFI
Post by: blacksheep on April 21, 2014, 06:23:36 PM
@MacVick - nope, no crashes or blackouts. My card is Gigabyte Windforce Rev. 2.0 - 1100/1500 MHz. Furmarked it good amount of times in OS X and Win 7 without problems. It passes all possible benches without thermal throttling. I'm powering it with internal power, using my custom power cables - 17-18 AWG.
If you have Win installed, run Heaven in window (extreme preset) and check temps and clocks with GPU-Z. You'll see thermal throttling there, if it occurs.

Works with r9 280x

Hello. I've bought the MSI R9 280X Gaming 3G for my 2010's Mac Pro. It's working well on OS X / Windows but, no boot screen…
I've already searched the forum more then an hour but, I just can't find the 7970 EFI rom to flash!

Where can I find it?
How do I change the name to "AMD Radeon R9 280X"?

Hello netkas.org !

I've been having trouble creating a rom for my new Gigabyte R9 280X (GV-R928XOC-3GD (rev. 2.0)) with my Mac Pro 5,1. I've been reading many threads here, but this is my first time flashing a graphics card so if I ask some really dumb question or made a stupid mistake don't hesitate to blast me, but I have done other hacks on my macs over the years so I'm not totally lost. I'd be grateful for any help you can give me.

I first installed the card with power and it ran fine in Mac OS 10.9.2 and Windows 7 without boot screens. Ran a few benchmarks and it responded as expected (pretty friggin' fast, great OpenCL performance).

I correctly extracted and backed up the card's original rom (r9280x.rom) via ATIWinFlash 2.6.7 from Bootcamp.

I can see that the EFI part starts at offset 65536 in Hex Fiend, but I don't get how the "padding" (correct word?) works at the end of the ROM file, so I thought it best to stick to Netkas' script.

Before getting the R9 card I had tested the script with ROM files from the web and had errors, so I started from a fresh bundle and the r9280x.rom from my actual card. No errors this time.

This gave me r9280x.rom.efi.rom.

I then tried flashing this file to the R9 card using ATIWinFlash in Bootcamp. It needed to run in admin mode, I did that, it went through it's thing then displayed:
(http://i.imgur.com/9miPJMZ.png)
I hit Start menu, restart, then Windows was blocked on the "Shutting Down" screen (waited over 15 minutes).

I hard reset the Mac Pro and the card was outputting only light grey screen, no Apple logo or anything. Mac Pro was accessible through file and screen sharing. Thinking maybe ATIWinFlash screwed up, I created a new ROM with the Netkas script (r9mac.rom), and went the FreeDOS route and a Nvidia GT 610 for video.

First I extracted the bad ROM for reference (r9bad.rom) and flashed the new r9mac.rom to the card:
(http://i.imgur.com/eQZsy0A.png)

Rebooted the Mac Pro. The card displays correctly again, but still no boot screens !

What am I screwing up ? :(

Hi wax2012!
I have the same card (Gigabyte R9 280X (GV-R928XOC-3GD (rev. 2.0))) and Mac Pro 5,1. card has two BIOS. One flashed (unsuccessfully), I use the second (Original bios). all is well, but without the loading screen!((
If you can make a good .ROM, share with me! I will be very grateful! thanks in advance ....)

@ 3mvideo & wax2012

check your PM (messages). I sent you something.
I flashed 4 of those Gigabyte Rev 2.0 cards for myself and my buddies. Everything (bootscreen, miniDP etc) is working fine so far.

Post by: wax2012 on May 15, 2014, 12:44:23 PM
Big thanks to Satrap for helping me out, his ROM works great, boot screen and all. Only tried one DVI and one MDP but both worked fine.

OS 10.9 defaults to 2560x1440 resolution, even in the recovery partition, but setting the system pref to "scaled" then 1920x1080 fixes that.

Ran a few benchmarks and only disappointment was Da Vinci but I was using 4K ProRes 4444 footage at 60fps so that was probably bottle necking my storage. I'll try it again with 2K stuff some other time.

Interestingly I tried booting to OS 10.7.5 and it sort of worked. Only the DVI port worked, and FCP 7 refused to launch saying I had less than 256 MB VRAM installed and no Quartz Extreme, but I had video out.

Avoid XFX R9 280X

I can verify that 2 separate cards like this have BIOS which is incompatible with OSX.

Stick with another brand

Probably best to find cards with Dual MDP instead of newer ones with single DP

If you want HDMI working, you need to use Reference 7950/70 and/or try different frame buffers.

This. Still the best choice by now imho. Swapped my Sapphire HD7970 for a Gigabyte R9 280X. The card is properly recognized, HDMI is working as well.

Mine is the BF4 LE (http://www.gigabyte.de/products/product-page.aspx?pid=4847#ov), basically the same as stock Rev. 2.0 (http://www.gigabyte.de/products/product-page.aspx?pid=4845#ov). Definitely a nice upgrade here in 10.9.3 / 13D65


Title: Re: R9 280x flashed with EFI
Post by: karterilla on May 28, 2014, 09:48:26 PM
I've flashed a Sapphire Toxic R9 280X (http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2023&psn=&lid=1&leg=0 (http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2023&psn=&lid=1&leg=0)) on a Mac Pro 4.1 early 2009 running 10.9.3.
The board has 2 DVI ports, 2 MDP and one HDMI.
I was unable to test both MDP working together or both DVI working at the same time, neither the HDMI since I do not have cables or displays to connect to.

I'm not really sure if everything it is working OK: for sure the upper DVI port it is not working at all in any test I've made, while the first MDP (whit a 27" LED Cinema Display connected) and the lower DVI port (with a 24" Cinema HD display connected) are working OK.
At boot I do have only the MDP port working while the DVI comes up after user login: I really do not know if this is bad or if it is OK... i.e. if I've correctly flashed the GPU!
On the original apple board both the 2 displays did come on...

Here some benchmarks. Seems OK besides OpenCL_OceanWave_Bandwidth_V161: is this bad?
On heavy load (Valley and LuxMark) the fans slowly increase the speed but it is still acceptable.

I've attached the modified rom if someone want to to give it a try. But I cannot assure it is really working.
Anyway I'm happy compared to very old original apple board I've used until now: it is like jumping to another universe

Thanks to all the people here for the help.

Hi Rominator and Blacksheep (and the rest of the gang online here),

Okay – I went back and spent a few hours studying the posts on the forum, and I think I'm ready to go. However, I want to check back with you guys before proceeding.

Requested Info:

Card: MSI R9-280x 3GB GAMING
http://www.msi.com/product/vga/R9_280X_GAMING_3G.html#overview
Mac: Genuine 2009 MacPro 4,1 with the 5,1 firmware upgrade
BIOS #: 015.042.000.003
OS: OSX v10.9.1 (10.9.2 was loop of death with dual 27” Apple Cinema Displays)
Pins: One 6-6 mini PCIe, One 6-6 mini PCIe with the 6-8 pin adapter; connected directly to motherboard. Runs fine unflashed in 10.9.1.
Displays: Two 27” Apple Cinema Displays, connected to both MDP on card.


1) Today, I set up BootCamp on my Mac on a separate drive, running Windows 8.1.  Downloaded and installed GPU-Z to dump the ROM, which was listed as “Tahiti.rom”.  Apparently, it’s the latest version for MSI, so I’m not updating it before adding the EFI.  Also installed ATI_Winflash, for when I’m ready to go.

2) Back on the Mac-side of things, I made sure to install Java and Python.  The flashing folder is at my root directory, and is ready for the script. Apparently, my device id is 6798. 

3) I have also installed HexEdit.  Which file will I edit to change the parameters for it to have it correctly show up in my system preferences? (R9-280x? 7970?) Do I use HexEdit to edit my original ROM?  If so, there was no 79xx string to change, from what I could see.

3) **** Here’s the kicker:  I spent quite a bit of time on the forum to try and find the correct EFI file for the 7970. I have the “7950mac.efi” file, but couldn’t find it’s 7970 counterpart.  The only thing I could find was “MAC7970.ROM”, which I finally found...but I doubt it’s the correct file; I’m guessing I need “7970mac.efi”. (Maybe there could be a sticky somewhere for people to find the correct files?)

4) After running the script, I will go back to Windows and run ATI_Winflash with the new file and will reboot (keeping my fingers crossed).

5) I’m fully aware about removing R17 for PCI 2.0 on the original 7950 and 7970 cards...Does this also apply for the R9-280x?  Attached is a photo of the backside...I’ve drawn a red rectangle around R17...which runs right through R18. If this correct, I’m assuming that using a low-powered soldering iron and touching the surface-mounted resistor back-and-forth should allow for easy extraction, correct?  Definitely want to double-check on this one as this didn’t seem clear in the forums for the R9-280x.

Again, I hope I’ve been diligent in doing my homework but I figure it can’t hurt to “measure twice and cut once” before proceeding.  Given that I’m using my Mac for daily work stuff, I want to make triple-sure things go smoothly before proceeding.

Many thanks to all you guys for all your help...especially netkas, rominator and blacksheep.  Cheers!


Hello to all. I've a Mac Pro from 2010. After some research in the forum, I've opted for the same card; the MSI 280X.
I've already tried to build the rom and flash the card. I was unable to do it and currently, the card is unusable!
I wanted to ask if some member that have the same card, could share a (.rom) and a (.md5) of it so, I can "reflash" and use the graphic card?
Any help would be really apreciated!

Kind regards,
Xanix

Hello,

I have a Mac Pro 3,1 running under os X 10.8.4 and my graphic card just died :-/
I need a new graphic card with 2 DVI outputs AND boot screen

I've tested 2 different 7850 and one 7950 and had the same results.
The 3 cards where recognized using the KEXT I found on the forum and both screens running fine.
I flashed the cards successfully, had the boot screen but one of the DVI output wasn't working anymore…

After having read this thread, people are experiencing more success with a 280X.
I'm in for trying to flash this one. Just in order to be clear, I can do it with the same rom made for the radeon 7XXX ?

Thx in advance and of course will keep you posted as far as the flashing goes…

I have several HIS 280X cards.  I no longer have a real Mac, but they did work in my Mac with and without EFI bios.  They work great in my hacks.  They overclock well.  As mentioned, if you flash the EFI be prepared for not all of the outputs to function properly.  I can't recall what I got working on real Macs with EFI.

Thank you all for your inputs. I have received the cards. 2 things that I would like to share, these cards have 2 x 8 pins pcie power plug, and be careful if you care about aesthetics, strangely I have received 2 type of cards, one is black with metal grill and the other one is kind of a gold colour with same design and grill as the black one. Weird thing is the product code of both cards are the same ??? Confusing...., sorry I bought bulk R9 280X so the ebay seller confirmed today that the boxes might have been mixed up as he had 12 units in all.

Anyway, I tested both cards on a PC, lowered down the GPU clock to be within 215-222W, flashed EFI. Boot screen on mac will show up on only 1 DP and DVI if you connect 4 monitors. Also there are some erratic screen flickerings that occur in Windows (bootcamp). But it does not happen on Mac...so further testing would be needed. At the moment, both cards have the same problem, even at stock voltage and clocks. Better stay away from HIS R9 280X.

THX for update Kenny. Regarding HIS cards: tomorrow I'll RMA 7870, which didn't survive a month of moderate usage (PS mostly). My last HIS card for sure. There were a few solid ones, 6870s for instance. Seems that GCN series of HIS are built with more crappier components than average.

New Guy here ... just wanted to jump in here and say:

I just got a flashed MSI R9 280x for my 3,1
From eBay vender macmotive
It's working great and it's very quiet.

But I did noticed that the Link Speed is 2.5 GT/s

1) Is it the same resistor that needs to be removed?
2) Can my old 3,1 really take advantage of a 5.0 GT/s?
3) Is one PCIx16 slot better than the other?

I'm not big on games but now that it looks like Apple is
making the video card do more & more work; I figured it's time
I understand them better ...

After reading through just this one subject
I have a better sense of how much I've yet to learn :)

I do use FCPX, Motion, Lightwave & Logic

Thanks

Hi north3d,

Your 3,1 can take advantage of 5.0GT/s but the difference between 2.5 and 5.0 is more or less negligible; the card can be placed in either Slot 1 or 2. Instead of enabling 5.0GT/s by damaging the circuit board, it is also possible to non-destructively enable 5.0 GT/s by using a conductive pen or epoxy to bypass the resistor, but I am not performing this modification currently as there is no real benefit.  I have responded to you directly with greater detail.

Thanks!

Hey guys, very new here and have an issue with a Mac Pro 5,1 running a Gigabyte 280x Rev 2.0.

Purchased it flashed with EFI (off eBay) so I get the Apple logo screen, but after that, the screen either goes black or gray and stays that way.
This happens with any version of 10.9 Mavericks or 10.8 Mountain Lion. However, it does boot into 10.7.5 Lion without any issues and the "About This Mac" section recognizes it as an R9 280X with 3GB.
I tried it in either of the 16x slots. When using the top one, I get the never-ending grey screen (after Apple boot logo). When using the bottom one, it goes to a black screen (after Apple boot logo) and keeps restarting.
I am using the supplied 6-6pin cable and 6-8pin cable.

How do I get this thing working on Mavericks?

P.S. - Also loads Windows 7 Bootcamp without any problems [edit: will no longer boot into Windows 7 Bootcamp; spits out BSOD every time and then restarts]

Hey guys, very new here and have an issue with a Mac Pro 5,1 running a Gigabyte 280x Rev 2.0.

Purchased it flashed with EFI (off eBay) ...


Which seller?

Hi Guys, i'm  thinking swap my Dual EFI Sapphire 7950 Boost by Dual Gigabyte R9 280X V2 or Dual MSI R9 280X what do you recommend me for best EFI Flash and Max Compatibility? Will i have problem with Crossfire in BootCamp? I like very much play BF4 :D at full.

Hi,

I need advice on how to flash 2 Gigabyte R9 280x Rev 2.0 cards with bootscreen, miniDP, an all the stuff. Read all the thread but didn't get a solid clue on how to do it (aside that several users succeed doing that).

Any clues?

Thanks!

Hi guys,

I flashed a Gigabyte R280X Windforce 2.0 with an self generated EFI. Under Mavericks everything is fine. However, today I wanted to install Yosemite final . When I try to boot from the external USB HDD ,prepared using Diskmaker X, I only get the strikedthrough circle and the MacPro reboots. I expect that the install disk is fine as I could use it to install Yosemite on a Mac Mini and Mac Pro running a flashed GTX680.

Does anybody have the same issue?

Did anybody succeed in installing Yosemite final on a Mac Pro running a flashed R280X?

How can I overcome the strikethrough circle issue? I've read that this sign indicates a non-signed driver but I would expect that all drivers on the install medium are signed.

Another point. Did someone managed to enable 5 GT/s on the Gigabyte R280X Windforce 2.0? The PCB layout seems to be very different from the reference design. Therefore I'm wondering whether R17 has the same function as in the reference design and can be "safely" removed to unlock 5 GT/s.

@ 3mvideo & wax2012

check your PM (messages). I sent you something.
I flashed 4 of those Gigabyte Rev 2.0 cards for myself and my buddies. Everything (bootscreen, miniDP etc) is working fine so far.

Dear Satrap. I have the exact same Gigabyte and I screw it up trying to flash it. Can you please send me the same file? I would be in gratitude. Greetings from Greece.

Hello guys,

i new here. I have a Mac Pro 2009 4,1.

I want to upgrade the CPUs and the Firmware, where I found all information.

Now I have the topic of GPU.

I looking what cards are suitable ...

for now I see the R9 280X as the best option. But after reading all of this Thread. I only learned Gigabyte R9 280X Rev2 should be the best.

But the following questions stay.

1. How Do I flash it?
2. Where do I get the Mac ROM ?
3. how you managed Power supply for the card? The Board has 2x 6 Pin. You need 8 Pin on the Card?
4. Where you got these mini PCI Kabels for the Mac Pro ?


thank you very much for help ...

Thanks everyone (especially Rominator) for this thread!

I flashed my MSI R9 280X Gaming 3GB and it works wonderfully.

However, System Information shows "AMD Radeon HD 7970". I edited that exact string in the second 64K (presumably Mac EBC firmware section) of my sewed-together ROM file to say "AMD Radeon R9 280X" but it didn't show up. Is it somewhere non-obvious?

UPDATE: figured it out. Thanks Rominator!

2. Where do I get the Mac ROM ? for the R9 280x ?
3. how you managed Power supply for the card? The Board has 2x 6 Pin. You need 8 Pin on the Card? Over 2 SATA to PCIe
4. Where you got these mini PCI Kabels for the Mac Pro ? (I GOT IT)

Is Geforce 970 or R9 280x  the better choice ?

@Rominator If it is a matter of just deleting the two kexts from /System/Library/Extensions/, then I've done that with no difference in performance.
Do I need to do more that just deleting the kexts?

After properly removing the 2 kexts, repairing permissions and rebuilding cache (important step) I know have almost as good performance as in Windows.
OSX is still 10% slower than Windows, but this is a difference I can live with...

Post by: Mr. Zarniwoop on November 17, 2014, 01:55:03 PM
For a related but different card: Mac Pro EFI firmware for an MSI R9 280 Gaming 3G (http://us.msi.com/product/vga/R9_280_GAMING_3G.html). (NOT THE R9 280X... this is the R9 280 "non-X" 2014 rebadged 7950.)

PC firmware is stock-as-shipped MSITV277MS.3E0 legacy BIOS version 015.044.000.005.000000, so if your card has this BIOS it'll probably just work. Keep the BIOS switch in the legacy position. That way the hybrid UEFI BIOS (http://event.msi.com/2014/vga/Hybrid_BIOS/) is untouched and still available with a flip of the switch if you move the card to a PC.

Mac Pro firmware is from netkas/Rominator bundle modified to identify as "AMD Radeon R9 280".

Not sure it's super-duper, but I didn't see any R9 280 firmware posted anywhere here so figured I'd share it in case it might help others in some way at some point.

Don't use Avid software so not sure what it requires. I have an R9 280X myself, I put that R9 280 firmware together for someone else.

Sorry to be that guy but can you point me towards the Netkas post you're referencing, or just list which kexts to remove?

As reported by OceanWave I've got extremely slow (maximum 45GB/second) GPU<->GPU memory bandwidth on a MacVidCards-procured 7970 running in 10.10.1 on a MacPro4,1 (flashed to 5,1) so I'm on the hunt for solutions! Thanks so much!

Hi all, just registered to share my info, cause i didn't find anything about Sapphire 280x Dual-X OC and particularly HDMI functionality.

Mac Pro 3,1 here, used mini6pin-to-8pin and 6-pin cable, card showed up unflashed of course, really slow results on benchmarks. So i flashed it, used netkas script, denisio's bundle, flashed it in win7 atiwinflash. After some gruesome dark restarts, suddenly it worked! It was still slow, so i deleted kexts, repaired permissions, rebuilt cache, and voila! Nice results, furmark 1920x1200 3751, luxmark 2236. Only bottom DVI and the HDMI works ATM, i don't have anything with DP to test it, but for me HDMI was the deal breaker so I'm relieved. During stress test with furmark, 40W on pci bus, 45W and 120W on pci boost ports, respectively.

Thanks netkas, rominator and denisio, and everyone participating in this endeavour. Hope my LB won't fry :S
Cheers!

Hello everyone,

This is probably a stupid question, but I'll take the risks.
My Asus R9 280X DC2T-3GD5 3GB card has flash type W25X20 (256 KB) according to ATIFLASH and whenever I dump my rom it produces a 256KB-sized file, which kind of make sense in my case, but all the rom files I've seen so far are 128KB.

Does it have something to do with the Dual-ROM feature?

I am ok with that, but my Blizzard games are not. WoW and Diablo now think that i have 2560x1400 resolution.

Hello Mr. Zarniwoop

I have the exact same system as you, a 2006 MacPro1,1 w/ flashed 2,1 EFI and SMC, upgraded CPU's, 32gb ram, and now I want to upgrade my video card from the venerable ATI 5870 that has served me so well all these years. 

What kind of performance are you getting, considering its still performing at PCIe 1.0 speeds?

I'll throw some numbers in, since I have swapped cards between a Mac Pro 1,1 and a Mac Pro 4,1.  Using Unigine Heaven 4.0, @ 1920 x 1080, max options, I have the Mac Sapphire Radeon 7950 running at 22 FPS on both systems, a flashed and resistor removed Radeon 7970 running 24 FPS on both systems, and an unflashed (PC) Nvidia GTX 770 running at 28 FPS on the 1,1 and 30 FPS on the 4,1, for a difference of 2 FPS.  At least from my numbers, your 280x should be close to my 7970, which shows no difference in performance with the bottleneck of the PCIe 1.0 bus.

Same thing! My flashed card also show unsupported resolutions for displays. Mine 20" and 17" displays now "support" 3200 x 2000 and 2560 x 2048 pixels, which is overkill for these displays. How to disable that excess resolutions?

What are the two kexts which need removing? I have a Mac Pro 3,1 with Yosemite 10.10.1 installed.

And is this the best way to rebuild a kernel extension cache in 10.10.1?

Think this is the post you're looking for:

http://netkas.org/?p=1325

It only mentions the Early 2008 MacPro and no other machines.

The two extensions to 'kill' are:

AppleIntelCPUPowerManagement.kext
AppleIntelCPUPowerManagementClient.kext

Somehow I have this feeling it might fuck up other models like the 4,1 and 5,1.

I discovered recently that my new 280x doesn't work with AE and Premiere. Tried CS6 and CC - Premiere hangs on startup, AE crashes with GPUSniffer error code 3. In 10.8.5 and 10.9.3.
No matter what I've tried – it doesn't work. Flashed and unflashed, named as R9 and 7970, added to openCL_supported.txt and with the file removed... Always the same error.
280X isn't even on supported list for PR Win version.
Other Adobe programs (PS, AI, ID, ME, DW, FL etc.) work well, only these 2 don't want to. What left is to test CC in 10.9.3.

Would somebody please post Specviewperf 12 benchmark results for EFI flashed 280x? Preferably both in OS X

Hello and thanks to all of you giving information and tools for flashing.

I acquired recently a R9 280X: VTX3D R9 280X 3GB GDDR5 V3 (http://www.vtx3d.com/products_features.asp?id=203), good price and working out of the box without boot screen. My computer is a Mac Pro 2006 (upgraded to 2,1 with 10GB of RAM). Both roms installed in the card are identical.

I tried with netkas script, but it gave error and after flashing it didn't work, so I had to reinstall the backup and tried modifying the EFI part with Hex Fiend as sugested from Rominator with his MAC7970.rom.

Everything works great since then, boot screen, no problems, but it is identified as HD 7970.

I tried to modify the references to 7970 in the rom file before flashing but I had not luck, and as I am not able to make the script work (I flashed previously a HD 5770 without problems but I cannot now) modifying efiromheader.rom and 7950mac.efi does not work for me , so could you please give me any advice about how to change it?. I now that it is only a cosmetic change, but I would appreciate any help.

Thanks again to all of you who support these forums and give us tools to maintain our old mac pros so powerful.

Regards

PS: I can attach the original or  modified rom if anyone is interested on it.

I acquired recently a R9 280X: VTX3D R9 280X 3GB GDDR5 V3 (http://www.vtx3d.com/products_features.asp?id=203), good price and working out of the box without boot screen. My computer is a Mac Pro 2006 (upgraded to 2,1 with 10GB of RAM). Both roms installed in the card are identical.

I tried with netkas script, but it gave error and after flashing it didn't work, so I had to reinstall the backup and tried modifying the EFI part with Hex Fiend as sugested from Rominator with his MAC7970.rom.

Everything works great since then, boot screen, no problems, but it is identified as HD 7970.

I tried to modify the references to 7970 in the rom file before flashing but I had not luck, and as I am not able to make the script work (I flashed previously a HD 5770 without problems but I cannot now) modifying efiromheader.rom and 7950mac.efi does not work for me , so could you please give me any advice about how to change it?. I now that it is only a cosmetic change, but I would appreciate any help.

Thanks again to all of you who support these forums and give us tools to maintain our old mac pros so powerful.

Regards

PS: I can attach the original or  modified rom if anyone is interested on it.

Hi Limonfrito,

I have the same card, can you post the modified rom please ?

Thanks,

Thanks Rominator.

I attach here the flashed rom for the mentioned VTX3D R9 280x v3.

This room has boot screen and is identified as R9 280x in osx.

Attached ROM is for the VTX R9 280X (http://www.vtx3d.com/products_features.asp?id=169) (not v2, not v3). Mac half by courtesy of limonfrito, first half taken from the manufacturer's ROM.

Further modifications applied:
  • Card has been limited to 224 W power consumption in order to respect the Mac supply limits
  • Fan response has been tuned to cool as much as possible - card will be almost silent in desktop use and will spin up its fans to max quickly when > 40 degrees Celsius

Thanks to everyone who contributed to this thread!

Hello everyone,

This is probably a stupid question, but I'll take the risks.
My Asus R9 280X DC2T-3GD5 3GB card has flash type W25X20 (256 KB) according to ATIFLASH and whenever I dump my rom it produces a 256KB-sized file, which kind of make sense in my case, but all the rom files I've seen so far are 128KB.

Does it have something to do with the Dual-ROM feature?

My MSI R9 280X Gaming 3G dumps a 256Kb ROM from ATIFLASH, as well.

How does this effect the patching procedure?

Hey guys.

Many of you are talking about a R17 resistor for making card goes in PCie 2 speed. I can't find a resistor with that number on my Gigabyte R9 280X Rev3.

This R17 was in the older card range. Have someone here making their Gigabyte R9 280X Rev3 Works on PCie 2 speed ?

What kind of modification was done ? Pictures ?

Hi,

I'm a complete noob, so please be patient with me!

I have a early 2008 Mac Pro (3.1) with a stock nVidia GT8800 video card. As you can imagine this is beginning to creak a bit! I also have a Sapphire R9 280X card (SKU ID: 11221-08) http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2072&psn=&lid=1&leg=0 (http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2072&psn=&lid=1&leg=0) from a BitCoin rig that was actually costing more in electricity than I was making (that's another story!).

I'm hoping that I can use the Sapphire card in the Mac Pro but am worried about frying the power. I have access to a Windows 7 machine and so can use atiflash to mod the bios but could someone please give me some (simple!) advice on what is the best thing to do (other than buy a new Mac Pro!)

Cheers,

oz.

Any progress on this? I too have an ASUS R9 280x DirectCU II TOP card with a 256k ROM. Since the UEFI part started after 64K I tried dumping only the first 128K, modifying the ROM with the 7950 EFI and flashing the modified 128K ROM. All I got was a black screen even past boot, so I had to revert to the vanilla ROM (attached if anybody can help).

I also have some strange results with the said card: Lexmark and Valley/Heaven benchmarks are in line with expectations, but Oceanwave is only 60fps (it should be 600fps!) and Lightroom CC is actually slower with GPU acceleration enabled ???

Hi all.  So I bought a Gigabyte r9 280x rev3 card to put in a 2009 4 core Mac Pro that I did the processor/ram upgrade for it to run a 6 core and 1333 ram making it show up as a 2010 machine.   

I am running boot camp with windows 7 pro.  I have read through the forum and I think I may have gone blind and stunned half way through.  I want to get a boot up screen so I can use if for both mac and pc.  This lovely computer is my mother's retirement gift so she can play the hell out of Tameriel Online, Far Cry, and Fallout.  Is there a post somewhere that is the idiot's guide?

Thanks in advance.

For proper results in Oceanwave you'd have to download Quartz Debug at Apple Dev and disable Beam Sync. Or just drag a finder window in front of the waves window to cover it.

10.11 OpenCL benchmarks are really promising. Attached below is a new all-time high I've got in OceanWave with El Cap DP3, in fps as well as GPU <-> GPU VRAM speed. Luxmark shows significant higher score too, almost 2700 in Sala

Hello,

I bought an VTX3D Radeon R9 280X Boost Edition V3, 3072 MB GDDR5 (VXR9 280X 3GBD5-2DHEV3) to put in my Mac Pro 3,1; because limonfrito was successful with that and posted his modified BIOS (thx!). But I couldn't flash it yet.

At first I got the problem that the card didn't work with 2x 6pin power cables I got from my old card. I bought an 6-to-8-pin-adapter and now the card works in OS X (without boot screen).

But the card does not work in windows. When I start the computer, press alt, right arrow, enter -> nothing happens. The screen stays black and no HDD activity. When I do this with the old card installed, it works fine (and I see of course the boot screen).

When I have both cards installed and I try to boot into windows, it flashes red on the screen: "one of your cards has not the power cable installed". Thats true because I only have enough cables for one card. But maybe this also shows up when I only installed the new card? But I can't see it because no boot screen support. But in OS X it works with these cables.

Not sure what to do. I didn't realise when ordering, that this edition is an overclocked edition (and draws more power maybe?). Could this be a problem?

UPDATE:
I managed to get another pair of 6-pin cables for my old graphics card. I booted into Win with both cards installed and flashed the new card using the BIOS provided by limonfrito (Thank you very much!) and now the card works like a charm in Win and OS X with bootscreen. I have no idea what the problem was. But now it works :)

Hi all,

I recently bought a Sapphire Vapor-X R9 280x 3GB GDDR5, but when I placed it in my mid 2012 Mac Pro / 5.1, running Yosemite 10.10.5, I expected that it would show at least the inlog screen after a full boot, but it does not show anything on whatever output port (DVI-D, HDMI and Display Port).
After reading through the various threads (wow what a lot) I more or less understood that the card is supported “Out of the Box” (?) and it only needs to be flashed when you want the start-up screens.
Is this correct?
Do I have the wrong card?

BTW, as everyone is flashing the EFI part at a certain offset in the ROM of their graphics card, I was wondering if anybody did any reverse engineering on that EFI part. Seems to me that in there might be the answer (probably be together with the Key Extensions) to which of the ports will be showing the so much appreciated start-up screens by default and perhaps also the number of monitors supported on those ports? (PCIe 1.0/2.1 support)? Just wondering.

Alla, I really am curious what your ideas are about my card and the EFI part.

Post by: Fl0r!an on September 16, 2015, 09:32:23 AM
Yes, the card is supported out of the box. Did you connect all PCIE power cables?

Regarding EFI reverse engineering, have a look here at this thread: http://forum.netkas.org/index.php/topic,10827.0.html (http://forum.netkas.org/index.php/topic,10827.0.html)

Hello Florian,

Thank you for your response and mentioning the thread about the "Radeon port mapping". As networking guy I use port mapping for something else :-)
I have just entered the Mac community (again) and now have a 5.1 Mac Pro and a 4.1 Mac Pro which has been updated to the 5.1 firmware.
When I put the Sapphire card in either machine it is not recognized. I can login remote from one Mac to the one with the Sapphire card, but notice that the Sapphire card is not recognized.

I do have two of exactly the same Sapphire Vapor-X R9 280X cards and can exchange those cards to the other Mac Pro's but the results remain the same.
And yes, I have 2 PCIe power cables connected, which I think is enough.
However, while writing this I realize that I use a 6pin wired connector on the PCIe side in stead of 8 pin.
As far as I know the 2 not connected pins are ground only and should not have any influence right?



Title: Re: R9 280x flashed with EFI
Post by: Fl0r!an on September 17, 2015, 07:59:27 AM
Those 2 pins can supply additional 75W. Some cards don't check if they're connected making them optional, but it seems your card needs them.

Apologies for the necropost - I have just recently come across a sapphire vapor-x R9-280x and am very interested in using it.  It has two 8 pin PCIe power connectors. 

I am planning to use this on a 2,1 MP - I wont need overclocking - but in its current state, can I plug it in the mini PCIe (using two 8pin pcie to 6pin mini pcie) to flash and down clock the GPU?  If down clocking, what would be the ideal parameter to set it to?

I try to falsh my card for mac with the rom creating test. I use ati win falsh on boot camp but nothing works :(

On windows the card works super and fine. On os x 10.11.1 i have gliches on mDP and on full res. of my monitor. after a while a get a blue sceen on mac (yes, dispalay shows me blue!)

the rom i attached was the original rom on the card. on widows 8 the card will shown normal like all other cards. on mac os not.

when i use a monitor on dvi with with a 1900 reseloution it works on windows. when i plug my dell 2514 with wqhd res it makes picture-glitches on win and mac and after a while it crashes into a blue picture on the screen.

the card is an gigabyte R9280X Rev. 2 Windforce OC (EDIT: GV-R928XOC-3GD/F60) - i allready tried the firmware from the post http://netkas.org/forum/index.php/topic,8757.msg28172.html#msg28172 but when installed the rom, nothing works.

Attached you'll find the EFI ROM for VTX3D R9 280X 3GB GDDR5 V2 (stock 2013 ROM treated with the script and 7950 EFI part). I made it, because the V3 ROM causes kernel panics on my 2,1.

Everything works great since then, boot screen, no problems, but it is identified as HD 7970.

Same thing here. I'd appreciate if someone would be kind enough to mod this file to R9 280x identification. I know it's cosmetic, but...

This drives me nuts!

I have the Gigabyte R9 280x, windforce 3x oc. Running 1.1 Mac PRO.

It runs perfect on standard rom, but no boot screen.

I asked if i could have the rom from some member on the board who was nice enough to hand me a rom and it works, kind of. It identifies correct in "about this mac" on capitain, but still no boot screen.

Is this related to 32 vs 64 bit boot.efi?

I would be VERY happy if someone could supply me with the ROM that works in 64 and 32 bit 1.1 Mac PRO.

ROM is EBC, it works on either.

Just sew your BIOS onto that working EFI, will be as good as it gets.

I did download the ROM from my card, another very helpful user put togheter for me a new ROM. I uploaded it to the card and it shows up and identifies properly but no boot screen. I dont know why. I am using the DisplayPort for my screen.

I dont have the tools or skills to do all this myself. And there is one million posts on several boards about this same issue. However there is no place where all the builds of the ROMs are actually collected, listed and made downloadable. It seems people keep on reinventing the wheel over and over again by spending hours to get this ROMs together. Downloading multiple programs in doing so. When all that should be needed is the correct ROM for the card and ATIWINFLASH.

Is there any place where i can just specify my kind of card (version of card), and download a working ROM? Or any post on this board where ROMs are collected?

If not so, is there a reason why this is not possible or is it just due to lack of interest from users to collect the ROMs in one single thread / post and make it really easy for newbies/noobs to just DL and flash? I am pretty sure it would save hours and hours of work, and all the people that actually does know how to do it would have less questions to answer over and over again.

This would a lot of work due to the countless number of different vendors, hardware revisions and BIOS revisions.
It's far easier the way it is, netkas' script will do all the work, no tools or skills needed.

Do you use a DP1.2 screen? I guess your card just doesn't like to give 4K boot screens...

You have a pretty good point there about the 4K boot screen, so i did remove the DP1.2 feature and try in HDMI. No success.

I used the BIOS from switchmode 1, that is towards the power cables on the card. I dont know if this was the correct BIOS to use but there was no complaints from the guy who helped me build the EFI ROM.

My card runs fine with all features working, i am connecting VGA, HDMI, DP to the same monitor and running PiP and it is very cool. Only thing missing is that bloody bootscreen. I dont know how to get it.

Is it possible that the boot screen is only showing on DVI (VGA) port? I tried Displayport and HDMI and none are working.

Would be nice if anyone had the same card and could just send a ROM that is verified working.

R9 280X 3072 MB
WindForce OC

This is some info about my card:
113-C3865000-X01 = Board ID
015.038.000.003.003435 = Original BIOS
0xF800 = Image size
0x3C00 = CRC

SN134601080607 = Serial# on the card itself

The card has dual miniDP, DVI and HDMI.

Ok!

Now i found one solution, booting from DVI-VGA adapter will give bootscreen!

This solution is good enough, but not perfect. It will help out every time that i need to swap between Windows/OSX.

Really good thing you mentioned this, because i would never have found out otherwise.

Do you think there is any way to make bootscreen from MDP or HDMI also?

Where were the R17 resistor mods on back? In nice even rows or staggered?

Staggered ones don't have working HDMI without other mods.

BTW, for many purposes HDMI = DVI. The passive adapters from one to the other are just rerouting same wires.

So a DVI to HDMI adapter might give you that.

You will never get a DP 1.2 boot screen from these cards.

Actually i didnt check the R17 resistor, because i have MacPRO 1.1 and cant get the high transfer rates anyways. But i tried the DVI-VGA and that works, also i tried the HDMI port and it works, also i tried both mDP ports and they work.

So it seems all my ports are working!

However, i hought a DVI->mDP and that one is not working at all. Seems to be some problems translating from DVI to mDP.

Seems to be a better solution like you say, to use DVI and HDMI adapter to get bootscreen. But i will not need the bootscreen except for special occations, so i can live with having it on the VGA.

Since my monitor is 4K i will never experience bootscreen anyways.

This basically means my card was Ok from the first flash all the time, but because i was running 4K mDP i was thinking it was not working and spent tens of hours looking for the answer.. Anyhow, i am happy now. I can reboot 10 times in a row just to see that bloody bootscreen ;)

Thanks guys!

Passive, i gave it back to the shop. It was simply a cable with DVI on one connector, and mDP on the other.

My monitor has DP, mDP, dual HDMI and VGA inputs. Total 5 inputs.

Ideally i would like to be able to run either 4K, or have the possibility to use PiP / 4 screen to view four different inputs at the same time.
As the screen is 4K, and has 40" of real estate (Phillips monster) its actually quite nice to run four desktops from one computer since i can then run four apps in full screen mode at the same time.

Problem with this screen size is that meny is far left top, apps ar bottom, and when new windows pop up that could be anywhere on the 40" screen giving me allot of moving around the cursor. When splliting into 4 different areas i can keep menus and everything on one screen and run apps on the other screens.

I still didnt try to run fullscreen apps in OSX. Before the other screens all turned gray but maybe they fixed it in el capitain.

Can really recommend this monitor for people who need allot of space!

Now i bought all the cables there are..

And the only boot screen i get is DVI-->VGA adapter and VGA cable, and also DVI-->DVI

I now have tried:
 DVI-->HDMI and no boot screen.
mDP-->DP no boot screen
HDMI-HDMI no boot screen
DP->DP no boot screen

DVI->VGA adapter and VGA cable Boot screen
DVI-DVI with no adapter there is ALSO BOOT SCREEN!

Why is the DVI-->HDMI not working??

My 40" monitor does not have DVI input. Only DP, HDMI and VGA.
VGA sucks, so i would like to use DVI. But DVI-->HDMI does not work.

I noticed that my DVI --> DVI cable is missing some pins in the middle (single link)
And the DVI-->HDMI does have all the pins in the DVI connector (dual link).

Will this be the source of the problem? I have now ordered some 5 different cables from ebay to get the bootscreen possibility, but non of them work. Strange enough i am experienceing HDMI port output problems when using the DVI-->HDMI cable.

And another strange thing is that the computer will not boot properly if i remove the DVI cable, it just needs to be plugged..

Anyone have some good ideas about these issues? Would be nice to know =)
Is there any solution to this or do i just have to accept this fact?

//GF

EDIT:

Just got this PM from another user, and i am updating the post with this info:

Did you ever solve your 40” monitor problem with your R9 280X ?

I’m running a flashed R9 270X and tried this and it worked  . .

Display Port Adaptor ( active ) to HDMI .. then HDMI to HDMI =  Boot screen

Hope this helps if you still have a problem.


/ ( SMIKX on Netkas).


However, i hought a DVI->mDP and that one is not working at all. Seems to be some problems translating from DVI to mDP.

Active or passive ?

Hello I have a sapphire Dual-x I'm about to try to flash. I found another a 280x rom somewhere around here and tried it. It worked. So I'm fairly confident in my ability to flash it, but I've never "modded" a rom before.

Anyway this card has dual BIOSes. I downloaded both. Looked at them. I think I used the "regular" BIOS. Then cut and paste from the 280x ROM I found. So here's what I have. Would someone mind looking at it and making sure I did it correctly before I break something haha. The "LightOff" rom is the unmodded BIOS.And the MyRom is my modded Rom.

Thanks in advance. And if I did this correctly this really is super easy to do. Which means I probably messed something up. Haha.

So it didn't work.  :-\

Can someone maybe look at them and see what I missed or did wrong? It works, I didn't brick it or anything. I just don't have a start-up screen. Back to black screen until I get to the desktop.

Thanks

Matt

I was able to get R9 280X DD from XFX working using Club3D rom.

Bootscreen works, fans are silent, performance is great, but card memory is reported incorrectly and Windows boots with BSOD.

Then checked the MSI rom for these specific Hynix memory modules, edited the clocks to match the XFX and now almost everything works but crashes on 3D apps.

So I made Sapphire ROM which works only with these Hynix modules and it does work well also in 3D ;)

Hey all.... From what I read of this thread it seems like the intent is to use the R9 280x on an actual Mac (Mac Pro), but if was to post my R9280X-DC2T-3GD5 ROM, would some one be able to flash and mod it to work on a Hackintosh?

Thanks in advance,
Shiggitay

There's no need to mod/flash anything on a Hackintosh.


Title: Re: R9 280x flashed with EFI
Post by: Shiggitay on October 14, 2016, 01:37:15 PM
Well then why won't my 280x boot up natively/directly on my Hackintosh?

Post by: Fl0r!an on October 14, 2016, 03:03:27 PM
Either it's a XFX card (which OS X doesn't like at all) or you've misconfigured Clover.

280X is still a pretty good choice as long as Polaris & Ellesmere support isn't quite there yet. Apple is still improving drivers...

Some compute benchmarks in Sierra 10.12.2 Beta 2, the numbers are getting better and better.

Attached you'll find the EFI ROM for VTX3D R9 280X 3GB GDDR5 V2 (stock 2013 ROM treated with the script and 7950 EFI part). I made it, because the V3 ROM causes kernel panics on my 2,1.

Same thing here. I'd appreciate if someone would be kind enough to mod this file to R9 280x identification. I know it's cosmetic, but...
Here you go.

I have VFX3D R9 280x 3GBD5-2DHEV2, no boot screen on this rom :( I attached the original rom, anybody can halp?

Another two R9 280X XFX cards (DD & Black Edition) which took a bit of time but both are running perfectly - only upper DVI and HDMI is inactive but all others works well.

Open the 7970 Mac file in a Hexeditor.

At 65536 you will find the EFI part.

Copy and paste into your R9 280X at same point, overwriting the UEFI, done.

For the Powercolor R9 280X (which works fine in High Sierra on a real MP5,1  the EFI part of the BIOS starts at 65412, not 65536.

What do I need to do to compensate for this?  My previous MSI card was pretty straightforward.

My original ROM attached...  Any help appreciated.



Title: Re: R9 280x flashed with EFI
Post by: vinnie1978 on February 08, 2018, 03:17:23 PM
That means the EFI part needs to start directly at that point.

Thanks.   I cut and pasted the EFI section in at 64512 and filled the space following it with FFFF and I now have bootscreens!

Here's my ROM if anyone else has the Powercolor R9 280X 3GB card.

PowerColor HD7950/HD7970/R9 280X cards all needs screws replacement to fit inside Mac Pro slot 1. Some of these also requires removal of the backplate to fit in.

Hi all. I am Sam. I have a display card which is Sapphire R9 280X. I finished to flash the rom and got pci-e 1.1 speed (2.5GT/S) showed in mac boot screen. I think I need to remove the r17 but I don't know how to do so. Please advise the method.

Thank you so much for posting this rom, I have a Powercolor R9 280X 3GB card, and I successfully flashed this, but first, it won't boot in Windows, and in MACOS, it chimes, gives me a multicolored lines screen, then doesn't complete that boot either.

Anyone have any ideas what I need to do to make this ROM work on *my* Powercolor R9 280X 3GB card ??

Hello , i am quite new to this forum but already an average MacUser (since 2004) .

I have a one-two question regarding flashing R9 280x:

- if i would buy off Ebay an unflashed Gigabyte R9 280x (used, as new they don't seem anymore available) could i be able to flash Mac EFI for Bootscreen in any case or would this be a lottery depending on which Rev. (1.0 or 2.0 or whatsoever) i would get?

- if i would be able to flash succesfully a Mac EFI Rom, would that automatically give me Full 5.0 GT Linkspeed or would i need to do further steps?


I am using a MacPro 5.1 and have a MacPro 1.1 with Bootcamp (Windows 7) also available.


Tips and Suggestions are very welcome, thanks!

Just make sure you get one with the reference card ports: One DVI, one HDMI and two mini DP. The later versions of the R9 280X have two DVI, one HDMI and one full sized DP ports and these are much less likely to work. Just skim through this thread, note the makes and models that flash without issue and concentrate on getting one of those.

With the latest EFI firmware update for the Mac Pro 5,1, you will get 5GT/s without having to do any resistor mod. The Mac Pro 1,1 is limited to PCIe 1.0, I believe, so your max throughput is 2.5GT/s regardless.

Post by: kapqa on August 17, 2018, 12:59:07 PM
Thank you for your answer,

i have looked on Youtube for a Resistor Mod to get 5.0 , it seems doable with the right tools, not too hard.

I don't know about a EFI update for 5.1 yet, if you mean that one coming for users running Mojave, read about that, would be great to be able to use any Radeon card whatsoever fully with bootscreen and 5.0 Linkspeed, but hopefully this update would not bring other limitations like impossibility to boot older OSX.

I mean this update:

http://netkas.org/forum/index.php/topic,13873.0.html

It doesn't provide bootscreens with non-flashed cards but it does allow you to update the MP's EFI without a flashed graphics card in future as well as dispensing with the resistor mod. You also don't need to actually install Mojave to install this EFI update. Just download Public Beta 6 and start the installation. It will prompt you to restart your Mac holding the power button in to put it into EFI update mode. After the bootrom is updated your MP will restart and boot to the Mojave installation screen. You can just cancel the installation.

You can still boot Snow Leopard with this bootrom.

I made this rom with the 7000 rom creation script, using a PC rom from another card. The Stock XFX rom wouldn't let the Mac boot.
This rom works, I get boot screens and it seems to perform fin in3D Benchmarks, but it reports 1182796800 MB of RAM.
I realise this is cosmetic, but I'd like to fix it if possible.


Spacedust  mentioned fixing the crazy memory but didn't go into detail about how its done.

Any help would be greatly appreciated..

Attached r9280x_ben_rom.efi.rom is the one I'm using, and xfxr9_280x_DD_Black.rom is the factory one.
