Заголовок сообщения:  Sapphire Nitro+ RX580 Driver Problem
Hi guys, a customer brought a Sapphire Nitro+ RX580 that did not have a picture, no fan spin. I checked and see there is no voltage on the graphic card except 5v and 3.3 from PCI express. All the fuses were ok. I replaced an AND gate on the board (you can see in the picture) and after that all the voltages are present and I have a picture, but on windows can not install the driver, it identifies as RX580 but with yellow triangle mark on device manager and not working as it should. I desoldered all the phase coils and checked with the oscilloscope, all 6 phases are working. I have not tried to reflash the BIOS as it is a dual BIOS version. Any thoughts. Can the GPU be damaged even there is picture??? is it possible?

While It can be a bad gpu, the most common reason for error in device manager with rx470/480/570/580 is non-AMD-signed custom mining-optimized VBIOS.

The simplest way to verify if it is the reason is patching amd driver:

If Card&driver is working fine after reboot - the reason is only in non-signed VBIOS.

  • Run atikmdag-patcher-bios.exe again, undo the patch.
  • Reboot computer - the yellow triangle appear again (to reproduce the issue).
  • Download VBIOS from techpowerup, and just flash it from windows
  • Reboot again.
  • If the VBIOS is signed and corresponds to the gpu - all will be working fine (if not - try another VBIOS from techpowerup)
  • After checking that found&flashed VBIOS is good - use card's mechanical switch to select another ROM chip and flash from windows again

The initial step with atikmdag-patcher-bios.exe is important stage of diagnostics: it allows to become 100% sure that the problem is reasoned ONLY by signature check before starting to trying different VBIOSes from techpowerup.

Rename it to atikmdag-patcher-bios.exe
Run, accept patching, reboot computer

Thanks for the reply. I tried what you recommended on the already installed driver (Date:01/13/2020 Version:26.20.15011.10003 beta) but after reboot, unfortunately, the same yellow triangle appeared and the result is the same. You think I should try an older version driver or try flashing different VBIOS?

https://www.monitortests.com/forum/Thre ... ck-Patcher says that atikmdag-patcher was tested only up to Adrenalin 19.11.3 Your driver looks newer...

However, even it doesn't helps - try flashing 1-2 official VBIOSes from https://www.techpowerup.com/vgabios/?di ... A2-E366-E7 , just backup the orginal. (no sense in trying more than 2, from my experience those bioses always work fine).

Also measure the resistance between L301 and ground. ~35Ohm is ok, ~2Ohm is dead gpu. (gpus burned by L301 power often are showing picture, but can't install driver)


Also, you may try booting any modern linux and try running linux verison of Furmark for example - its amdgpu driver does NOT check VBIOS signature.
If it runs furmark on linux without visual problems - then the gpu looks to be physically fine.
