Hi,

I just built a new PC with a Club3D R9 295×2
However, when I disable CSM, the motherboard (Asus Z97 PRO-Gamer, flashed latest BIOS already) complains that the graphics card is not UEFI-compatible, and re-enables it.

However, when I browse the Club3D website for a newer BIOS, i just get redirected to the AMD-website.
Do you have a UEFI GOP-BIOS that I can flash to my GPU (CGAX-R9295X29) so it will work?

Regards,
Niels

Hi,
Can you send us the GPU-Z data so we can check for the UEFI BIOS?

Please send it to [email protected]
Thanks

Done!

Thanks.

Hi,
Please find the new BIOS here.

Make sure you backup your BIOS file

1. RENAME THE FILE TO 295X2.ZIP
2. EXTRACT THE FILE
3. BECAUSE THE 295X2 HAS TWO GPU’S, YOU NEED TO RUN FIRST MASTER.BAT AND THEN SLAVE.BAT
4. AFTER YOU COMPLETE FLASHING SECOND BIOS, JUST REBOOT AND CHECK UEFI VERSION.

Hi Paul,

The flashing utility seems to be made for a 32-bit OS, but I am currently running Windows 8.1 64-bit, so I cannot run it.
Could you send me a 64-bit version of the flash utility?

Thanks!

Hi,
I have to check. Will get back to you.

Any news yet?

Paul 0 on 24-04-2015

Hi,
We are awaiting to see if there is a utility for 64 bit. We sent the feedback to AMD and so far no response. From what they explain it should work for both 64 and 32 OS.

Hi,

When I try to run the program, I get an error message saying that atiflash.exe is a non-supported 16-bit application that cannot run on Windows 64-bit.

I hope that this information helps.

Niels

Hi,
Have you tried using a USB DOS boot disk and run DOS to flash the BIOS?
If you are trying to run the atiflash.exe in Windows DOS command window it will not run.

xIntenso 0 on 27-04-2015

Dear Paul,

Running the commands from a DOS USB does work.
However, the GPU now gives no image whatsoever after flashing (I tried multiple times).

When i boot with the iGPU of my CPU enabled, however, I can see the GPU in device manager.

Any idea how to fix this?

Regards,
Niels

xIntenso 0 on 27-04-2015

By the way, if I can boot with the iGPU, that means that the BIOS does not see the GPU anymore.

Paul 0 on 28-04-2015

Hi,
Where are you located? I think is best that you can send us the card so we can do the flash here.

Did you flash the BIOS in the correct way?
There is a master and slave BIOS. Please try to disable under your BIOS the UEFI to check the problem.
The R9 295X2 has a slider button on the top, this is the second BIOS of the card. If you switch the button when the system is off and when you run it goes into non UEFI mode.

xIntenso 0 on 28-04-2015

Hi Paul,

I’m located in the Netherlands.
I flashed the BIOS with the following procedure.

– Create a DOS USB with Rufus
– Put Motherboard BIOS in Lecacy mode and boot from USB
– Copy atiflash.exe, the 2 BIOS files and the .bat files to the root of the USB
– Run master.bat
– Run slave.bat
– Reboot

I’ll try the slider button and will report back soon.

Could you try to explain the flash procedure in detail?

xIntenso 0 on 28-04-2015

P.S.
I am curious as to how the master.bat and slave.bat select the correct GPU’s, because the commands listed in the .bats only differ in the name of the BIOS they have to flash.

Should I be selecting the device to flash to in some way?

xIntenso 0 on 28-04-2015

The GPU lives!

I looked up how atiflash.exe worked and discovered a (quite serious) flaw in the .bat files: They both flashed to GPU 0!

This meant that first, I would correctly flash the master BIOS to GPU 0 (the master GPU), but after that I would immediately overwrite it with the slave BIOS, while also leaving the slave BIOS at an older version.

Once I had changed slave.bat to write to GPU 1, it flashed correctly and my GPU is now running happily without CSM

Thanks for the help, I hope this will prevent future failed flashes.
Regards,
Niels

Hi,

@Paul could you please re-upload the bios?

The Dropbox link says the item was deleted.

There is a UEFI enable VBIOS in the techpowerup VGA BIOS Collection with a BIG warning :

“Warning: You are viewing an unverified BIOS file.

This upload has not been verified by us in any way (like we do for the entries listed under the ‘AMD’, ‘ATI’ and ‘NVIDIA’ sections).
Please exercise caution when flashing it to your graphics card, and always have a backup.”

While almost all other VBIOS are version 015.044.000.009.004297 , this unverified one is 015.047.000.001.000000

Did anybody try it?

Can anyone confirm it works?

Only made an account to tell you that I just tried that Bios aswell as the Slave one (Beware that your linked one is only the Master one, the Slave one is also in the database)

Anyways

UEFI works, I disabled legacy bios support in my mobos bios and it runs on W11 fine with Amermine Custom Drivers (You should get them if you run pre-polaris cards)
