Interesting. You hold the crown for low fan speeds with your MSI R7950 Twin Frozr 3GD5/OC.

Given this card has higher clock speed than the Sapphire Mac version and due to its different cooler blows heat inside of the Mac Pro case, I would have expected the opposite. Huh

I had a similar cooler on the Sapphire 6870 OC version previously installed in the system. It´s very effective. I believe the Mac edition of the 7950 has the stock reference design. While it might "blow the air out" It still has a plastic shell emitting heat. When idling, there shouldn't be much difference between 800 and 880Mhz but the cooling effectiveness plays a bigger role. I´m using the lowest PCI-E slot so the CPU/RAM cage might soak up some of the heat behind the card.

I can upload my ROM if you´d like to try it on your card.

Hey Rom-Guys,

thanks for writing these patches.

Today I got my Sapphire 7950 Boost (Dual Fan). Now I patched my extracted ROM and flashed it back. Bootscreen works fine, but I can't boot my 10.8.3 with chameleon (yes I'm running an 1,1 MacPro).

I got the following error:

Code:
Memory allocation error! Addr: 0xdeadbeef, size: 0x0, File: ati.c, Line: 965

This is a non recoverable error! System HALTED!!!

Do they want to try kidding me? "deadbeaf"-adress? three "!!!"?


DEADBEEF   "Dead beef", Famously used on IBM systems such as the RS/6000, also used in the original Mac OS operating systems, OPENSTEP Enterprise, and the Commodore Amiga. On Sun Microsystems' Solaris, marks freed kernel memory (KMEM_FREE_PATTERN)

So basically you have some memory alloc errors in your ati.c (freed memory section access), maybe thats because of 32/64 bit issues dedicating different amounts of space for data-types.. maybe..

2. A card flashed with the pure Mac 7950 EFI & BIOS that I posted will run at the Mac speeds in both OSX and WIndows and at 2.5 GT/s on the PCIE bus.

I know in reality there is close to no difference performance wise in running the card at 2.5 GT/s vs. 5.0 GT/s.


FInally we have some indications of what this limitation means.

We sent a 7970 flashed to work at PCIE 2.0 to Barefeats to be included in his tests.

The 7970 he already had was a Ghz Edition so faster than the regular one I sent. It was completely unflashed.

I think the truly interesting thing is the places where the regular one BEAT the overclocked one.

The ONLY difference being that ours was running at 2.0

In the Civilization V benchmark, the DaVince Resolve Test, The FCPX test and the PS6 test (where our 7970 WON !!!). In all 4 tests, despite running at lower clocks on both RAM and GPU, our card was able to "come from behind" and beat the faster card running at 1.0

So we finally have conclusive proof that there are places where it makes a difference. The results would have been even more dramatic if the 2 cards being compared had been equals to begin with.

Thx @Netkas,
Thx @Rominator,

i used the patch script netkas wrote and can confirm i have no issues atm whatsoever, and i have nice boot screen(s) with 2 monitors via miniDp  Grin.

I used the Reference Design Card of Sapphire just with the twin-cooler. 11196-16-40G which seems to be harder to get at the moment because its the old Reference Design with the twin-cooler.
Super silent. abt 1490 points in furmark.  comes with 850 Mhz and 1250 Mhz and boosts to 925 Mhz what i wrote from the spec, so should even be a little faster than the Mac Edition and definitely less noisy.
Runs on my pro(08), whilst other cards seem to have troubles running smooth.

Maybe you can even flash this ROM on the original sapphire card and see if the performance increases a little..

I'll donate gladly, thx for keeping up your great work!

Cheers!

Edit:

Fan-Speeds:
Idle: 33C
CPU_MEM 499
PCI: 799
PS: 650

P.S. It is ONLY FOR MACPRO, hackint0sh doesn't need this, it will not make hackint0sh run a little bit better

OK, and what about todays hackintosh system based on uefi board and uefi bootloader ? I'm just wondering what will happen if we put Mac Edition card or flashed one to hackintosh - will be Apple boot screen there ? Any benefits ? How such card will behave?

I would also like to give my thanks to Netkas, Rominator and the team for making the EFI script available to us.

I have successfully EFI-flashed my Sapphire 7950 Flex OC With Boost (11196-17-40G). I get the boot screens and still have the GPU 925MHz, MEM 1250MHz speeds. I am very happy with my purchase and now have the confidence of knowing there are boot screens on it too.

EDIT : Fan speeds

Temp 29C
PCI 800
PS 600
Exhaust 600
Intake 600
BoostA 850

if you have a hackintosh and are using chameleon boot loader, you should already have boot screens.

I'm wondering about UEFI bootloader - Clover and UEFI boot with EFI Mac card not Chameleon...

I think most AMD 7000 series cards have a UEFI bios from the factory, but flashing the mac EFI bios on a PC wont help\make any difference. Mac EFI and PC UEFI are different.

Hi, had some guys from a local post house drop off some 7970s for EFI flash and 5.0 enable.

I have discovered that the non-reference 7950/70 cards have similar output ports, but the HDMI port isn't functional both pre & post flash.

Can everyone running a 7xxx card check their HDMI and report back?

The end result is that these cards currently only run 3 displays whereas the reference cards run 4.

It may be possible to find another personality or rom mod to enable 4 but would be good to gather info here first.

Hey Rom-Guys,

thanks for writing these patches.

Today I got my Sapphire 7950 Boost (Dual Fan). Now I patched my extracted ROM and flashed it back. Bootscreen works fine, but I can't boot my 10.8.3 with chameleon (yes I'm running an 1,1 MacPro).

I got the following error:

Code:

This is a non recoverable error! System HALTED!!!

Do they want to try kidding me? "deadbeaf"-adress? three "!!!"?


Has anyone else tried the card in an 1,1?

@Rominator: I think at macrumors you posted that you installed the original mac 7950 on an 1,1 MacPro. Did it run on 10.8.3 booted with chameleon? Did that work flawlessly?

Hope I get it running soon.


PS: Win7 is running fine.

GraphicsEnabler=No and it will go further... Not so much, though.

Drivers do not work with 1,1 in 64-bit too.

Last night I've chameleonized my 1,1.
Tried 10.7.5 first with 2 cards: flashed 7870 and unflashed 7950, Sapphire drivers (added 7870 DID to ATIX4000.kext).
With GraphicsEnabler=No, otherwise I got deadbeef.

Bootscreen, spinning gear, then after loading driver flickering, grey screen or restart, like in 32bit.
What's interesting: every time (with both cards) when driver was loaded I was getting red LEDs on logic board: CPU A and CPU B. This indicates bad PCI card.

Tested 10.8.3 next, with built-in drivers. Exactly that same as in 10.7.5 but without red LEDs.

My guess: drivers do need some hardware-specific functions (not present in 1,1), otherwise they crash com.apple.iokit extensions.
Maybe it's a matter of PCI 2.0?

Below part of KP log when I put unflashed 7950 in 10.7.5 in 32bit mode:

Rominator - you are right - no HDMI output in OSX.

Card : Sapphire 7950 Flex OC with Boost (11196-17-40G) flashed with EFI
Ports : 2x mDP, 1x Dual link DVI-I, 1x HDMI
Monitors : Apple 27" ACD on mDP, Philips TV on HDMI

OSX : ACD displays 1440p desktop but TV reports No Video Signal on that HDMI port
Win7-64 : ACD displays 1440p desktop, TV displays 1080p Win7 desktop and mouse moves across both screens as expected.

Thank you for testing this.

With release of Kepler EFIs I have been very busy.

But sooner or later we WILL get to the bottom of this.

There must be a way to get these cards working in 1,1 and 2,1.

So very tempting with EBC rom that gives lovely boot screens, just no driver afterward except in Windows. (Silly, yes?)

Happy to report this worked very well.

XFX 7950 DD 3GB
Mac Pro 4,1 original BIOS
Flashed with ati_winflash

The one minor issue is that OS X thinks my screen res are higher than normal, as others have noted, but setting to scaled at the correct res fixes the issue.

Thanks
