R9 295×2 not working with UEFI/Secure Boot

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.

on 24-04-2015

Any news yet?

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.

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.

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

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

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.

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?

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?

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
