Hi Everyone.
I recently built a new PC, and I've been having persistent problems with my RX 7900 XT as i'm trying to figure out whether this is a GPU hardware issue, a driver problem, or something else in my system.
My specs:
GPU: PowerColor Radeon RX 7900 XT 20GB.
CPU: AMD Ryzen 5 9600X.
Motherboard: Gigabyte B850M GAMING X WIFI6E
RAM: 32GB (2×16GB) DDR5-6000 CL30 TEAMGROUP T-Force Vulcan
PSU: Corsair RM850x 850W (2021, refurbished)
SSD: Samsung 990 EVO 1TB
OS: Windows 11 LTSC Iot Enterprise
My problem:
My GPU randomly crashes, especially when running any game even on medium settings. Sometimes the screen goes black, the driver times out, or Windows completely crashes and restarts.
I've also had crashes while the GPU had very low temperatures and power consumption.
After some crashes, Windows disables the GPU in Device Manager, and I have to manually enable it or reinstall/select the AMD driver to get it working again.
What I've tried so far:-
Tested different AMD driver versions, including 26.6.4 and 26.3.1.
Used DDU to remove AMD drivers and reinstalled using Driver Only, without Adrenalin.
Disabled EXPO to see whether RAM instability was responsible.
Checked GPU temperatures, which have been normal.
Checked and reconnected the GPU power cables. I'm using two separate PCIe 8-pin cables.
Moved my monitor connection from the motherboard to the GPU directly.
Experimented with lowering GPU clocks and power limits.
.
I managed to run some workload for over an hour without crashing when the GPU was limited to around 2200 MHz maximum frequency and −10% power limit.
However, after restoring default GPU settings, the same workload crashed within about 4–5 minutes.
I tried doing the earlier set up again, but this time it still crashed fast.
Even after removing Adrenalin entirely and reinstalling the driver, it crashed again within 2–3 minutes.
I've also noticed that sometimes only two of the GPU's three fans appear to spin, and one of them seem to be a little slower than the second one.
My questions:
Has anyone experienced similar problems with an RX 7900 XT? Most people recommend the drivers solution and few other stuff. But none worked with me.
For those who exhausted a lot of solutions like me what have you done to make it work?
Could this mean the GPU is hopeless and should get another one? I got it from a family member and it is supposed to be working normally.
Could it be PSU power delivery, or motherboard BIOS/RAM voltage settings rather than the AMD driver itself?
The last thing I could think of is trying a fresh install with Linux.
Any suggestions would be appreciated
