Hi everyone, I am posting this because I am running out of ideas and I would love some help from people that know more than I do.
My setup:
- Ryzen 7 9800X3D
- ASUS TUF GAMING B850M-PLUS, BIOS 1681
- 2x16GB Corsair Vengeance 6000 CL30, EXPO enabled
- ASUS Radeon RX 9070 XT 16GB
- AMD Software 26.3.1 (driver 32.0.23033.1002)
- Windows 11 Pro 26H2 (build 26300.9711)
The card is under a year old.
What happens is this: the picture goes completely black, but the computer is still alive. Windows sounds keep playing, Discord keeps working, and in a call people still hear me fine, my mic is still picking me up. It is only the display that dies. Sometimes it comes back on its own after a few seconds, sometimes I have to force restart the PC, and sometimes the PC does not come back with the card at all.
That last case is the one that worries me. After a few of these, Windows comes back and the GPU is simply not there. It falls back to the Microsoft Basic Display Adapter and nothing I try brings it back, just restarting the Windows "fix" the issue.
I went through my event logs and this is not only a cosmetic stutter thing. There are LiveKernelReports WATCHDOG dumps (TDR timeouts) on 26/07, 17/09, 19/09, 05/10, 07/10 and 08/10, and on several of those dates the machine had to be reset by hand (Kernel-Power 41).
Most of the issues are DX12 related.
AMD support suggested to disable hardware acceleration from things or HAGS.
Things I have already ruled out as much as I can:
- Memtest86 overnight, 4 passes, 0 errors.
- OCCT VRAM test, completely clean.
- I have never undervolted anything, GPU and CPU are at stock (just PBO).
- Stop windows update, remove internet, perform DDU.
- I have tried several Adrenalin versions by now. 26.3.1 is the one that behaves the best for me, but it still lets one through every once in a while, so I do not think swapping drivers is the answer.
I have seen the same thing mentioned by quite a few 9070 XT owners and a lot of these "timeouts".
Two things I want to try and I would rather ask before doing it:
- Disable EXPO profile and try some settings by myself.
- A clean install of Windows with ReviOS or smthn.
Two smaller questions if anyone has an opinion:
- ReBAR is enabled on my board. Is that worth turning off to test with a 9070 XT?
- When the card is not detected after a crash and only comes back with a cold boot, does that point to the GPU being on its way out? I would like to know if I should start looking at warranty before it dies completely.
Thanks a lot in advance for reading.
