This is a copy paste of the troubleshooting form I submitted to /r/amdhelp as I was having trouble getting on here.
GPU: RX 7900 XTX Sapphire reference model
CPU: RYZEN 9 7950X 16 CORE 32 THREADS
Motherboard: ASUS ROG X670E-F WIFI
BIOS Version: 0805
RAM: 2x32G Corsair Dominator PltRGB DDR5 5600
PSU: Corsair RM1000x Full Mod PSU
Case: Corsair 7000D AIRFLOW FT Black
Operating System & Version: WINDOWS 11 PRO 22621
GPU Drivers: AMD Adrenalin 22.12.1
Chipset Drivers: AMD 5.12.0.38
Background Applications: DISCORD, CHROME
Description of Original Problem: Getting irreversible corruption on my main screen upon loading into certain demanding games (see image).
In particular Warhammer total war 3, I click continue campaign and it loads up the campaign map, sometimes ending in the below screenshot, sometimes working perfectly fine. repeating the process when transitioning from the campaign map to the battle map.
Similarly had this happen when loading the superposition unigine benchmark and loading in between missions on warhammer darktide.
If I manage to get past the initial loading without incident everything runs pretty smoothly, so there's definitely something strange going on here (perhaps with VRAM?)
Troubleshooting: Have triple checked the power connectors to the card from both ends (it has two separate 8 pin connectors), have reseated the card. Have reinstalled the drivers and have reinstalled windows. I have also disabled mpo in windows as it was mentioned to have caused similar problems in the past. Have plugged my stuff into a power calculator and i'm well over the 100% usage requirement.
Looking at the performance data in adrenalin (on my second screen), the card is functioning fine during the corruption and the application that's corrupted isn't actually crashing (at least not immediately). The card was happily chugging along at around 344 watts 98% utilization with no real variation.
It is important to note that i'm running a multi monitor setup, however I can still get this issue if I turn my second monitor off.
My primary monitor is running at 120hz 4k with HDR enabled (have tried disabling HDR as well)
Second monitor is 120hz 1440p.
Both are some level of gsync/freesync compatible.
Any insights would be greatly appreciated, I might look into swapping my old 2080ti to see if it really is just a GPU issue. At which point i'll consider RMAing this brand new card
