7xxx rom creating test.

[Beegle]

Ok so instead of the msi i got the HIS IceQ Turbo 7950 and flashed BIOS 1 to blacksheep's HIS 7950 rom and it seems to be working fine except one thing, on my up2414q monitor when i set it on dp1.2 it splits the screen into two and switching to the backup BIOS 2 (pc bios) it just seems to ignore dp1.2 and stay at 30hz atleast on the mac bios i can switch to 60hz but it splits my screen into two screens and letterboxes them. i really only wanted to do this upgrade to get 4k 60hz but it seems it's not going to work. Good new is graphics stuff seems snappier and mouse lag with the 30hz is a bit less and i can scale the res to a larger res instead of before with the 5770 i could only 4k scale to 1920x1080 now i have it set at 2048x1152

connected with a mini displayport to mini displayport adapter, mac osx mavericks 10.9.5. i haven't upgraded to Yosemite cause some plugins i use don't work with it yet (although i don't think they do) but i'd sooner wait a while.

it's obviously a MST issue but just wondering if there is a fix for it?

EDIT: further research suggests that 4k 60hz is working with a 7950 in Yosemite but with a SST 4k monitor (Samsung U28D590D) this is however a TN panel.

Has any one tried this card in Mac Pro 2,1?

Powercolor Radeon HD7750 4GB

Hoping you can help. I've read through the thread a number of times and i think i'm making the correct rom but i still don't get an EFI screen.

The card i'm using is an R9270x 2GB (sapphire Vapor-x PN 299-1E280-000SA) (sku 11217-00-20G)

The card works fine but with no efi.

I used darwindumper to extract the video bios. The resulting filename is 1002.6810 so i am assuming the deviceID is 6810.  Its a 66k file. I renamed the file r9270x.rom and moved it to the same directory as the makerom.sh script.

I use the command in terminal:

./makerom.sh --efifile=7950mac.efi --romfile=efiromheader.rom --originalrom=r9270x.rom --devid=6810

The output is :

running on 7950mac.efi, efiromheader.rom with devid 6810

RawData (size=17408)
the rom is ready at r9270x.rom.efi.rom

The resulting file is 133kb in size.

I then take this rom, boot into Windows 7 on the mac pro. I use ATIwinflash (2.6.7) to flash this file to the card. The progress bar proceeds and it tells me it is done. Restart the machine - no boot screen. (on one occasion i got not OS X graphics at all, had to reflash the original darwindumper output back which returned me to the original state - so i think that the ATIwinflash is doing something.

Could anyone please have a look at the rom file (attached) and perhaps advise me on where i've cocked it up?

Please make me a uefi rom, i try but not luck
I flash my card with 7950 Mac Edition.bin, and runs ok but i need my bios modified and funs run slow.

Hi guys, need some help.

Read the post completely and tried script & 7950Mac edition rom posted earlier but got no display on DVI or nDP. Card otherwise works as 7xxx in OS X and works fine in Win 8.

Following pretty standard procedure of GPU-Z and atiwinflash. Card is a SAPPHIRE HD 7950 3GB GDDR5 w/Boost (DualX). same as this http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1713&psn=&lid=1&leg=0#

http://gpuz.techpowerup.com/15/03/08/5tc.png

Backup rom and efi rom attached.

Unless this is the card where efi is no good, I don't know what I'm doing wrong. Help would be appreciated

Thanks for your reply. I have exhausted my ability to get my 270x to work using this forum. If i can provide an original rom from the card would someone consider making the EFI part and joining them together for me - say for $100 paypal ?

[Rominator]

does the card work without an EFI?

If it doesn't, a rom isn't going to help much

Should self init for basic function

[gavster1234]

Hi Rominator, appreciate you taking the time to reply. The card Sapphire R9 270x does work, and is stable but without a boot screen shows as a 7xxx series (for this particular machine it would be very helpful to have boot screen). So i am trying to see if it is possible to add the EFI to do this (my attempt is posted above, but resulted in no video at all). The deviceID of this card shows as 6810. My understanding is that the R9270x is a 7870 variant?. I've seen posts on this forum that elude to some people getting the EFI part to work for 270's, but i have been unable to find any combined rom/bios to download and try. I can't work out where to look (sorry) to find the list of compatible / supported deviceID's and see if 6810 is listed.

I have managed to successfully flash a R9 280x previously (another sapphire card in another machine using SATA power leads etc), (but only with a combined EFI and bios that i found, not with one i made using a similar procedure as above) so i know that my flashing procedure does work (atiwinflash) but am unsure as to whether i am using the rom creating script correctly.
So my questions are :
1. Have you had any success adding an efi to a R9 270x ?
2. Is Deviceid=6810 a valid argument in the script ? (./makerom.sh --efifile=7950mac.efi --romfile=efiromheader.rom --originalrom=r9270x.rom --devid=6810)
3. Is there a 7870mac.efi or equivalent to swap with the 7950mac.efi ?

Once again, thanks for your reply.

nop no boot screen. i not understand
please help me and i send to you a beer

[gavster1234]

Got the R9 270x 2Gb Saphhire working. It seems the the darwindumper output wasn't wasn't generating a suitable  combined EFI/bios with the script for some reasons. I used GPU-z to dump the original rom, then ran the script. Flashed using AtiWinflash. Now EFI working (not all ports but a good start). Thanks to those who were having a look.
