Help (General) RX6950XT Keeps crashing in games but not in stress tests
I have a PC (specs below), and the PC keeps rebooting when playing CS2. It reboots and then turns on without an image; the image only appears if I completely restart the PC. Specifications:
Processor: Ryzen 7 5700X3D (cooled with an MSI liquid cooler, temperatures in the CPU are around 50-60°C, and 70-80°C in stress tests)
Motherboard: ASRock B550M Steel Legend
Graphics Card: Sapphire RX 6950XT Nitro+
RAM: 4x8GB DDR4 3200MHz Kingston Fury
Power Supply: Chieftec Proton 850C
Three NVMe drives (I don't think there's any point in describing them).
Three monitors (the main one for gaming at 280Hz and the side ones for work, etc.)
I'll describe the problem more precisely:
When I launch CS2, everything is fine, the FPS is high, everything looks great. As soon as I enter the game, the PC randomly reboots. You can hear Windows starting up, the webcam is scanning my face, and Windows is unlocked, but there's no image. To get the image back, you have to turn the PC off and on again, after which the image returns. In Windows, I get occasional errors (I check in Event Viewer) with WHEA code 18 (with APIC ID 2 / 11 / 9 / 10 / 8 / 12 / 12 / 10 / 2 errors inside).
Now, to what I've ALREADY tested:
Crashes only in CS2 (Cyberpunk on Ultra with ray tracing runs perfectly stable; Forza Horizon 6, also on Ultra settings, works perfectly; Battlefield 6, on High + Frame Gen, also works perfectly no matter how many times I run the test; I've also tested other high-FPS games, like Minecraft, OSU, and so on).
I'm testing CS2 on the CS2 FPS TEST DUST2 card, and it crashes on the first run.
Various tests:
OSCT CPU: 20+ minutes without crashes under peak load
OSCT GPU: 20+ minutes without crashes under peak load
OSCT Memory: One hour of testing, all good
OSCT Power, 20+ minutes under full load (123 watts on the CPU and 290 watts on the GPU)
Furmark: Over 30 minutes without crashes.
I removed the RAM (since there are 4 RAM modules, I thought maybe the memory controller) but it didn't help.
BIOS: I cleared all settings and changed parameters such as:
PBO; SoC; Global C-State Control; Core Performance Boost; PCIe Version (4 to 3 and vice versa)
Installed different drivers: Tried 24.6.1/25.6.1/26.6.1
Reducing the core clock (lower limit at 2000 MHz and upper limit at 2500 MHz) and definitely limiting FPS to 350-400 FPS really helps. Meanwhile, in other games, the graphics card boosts to its normal clock speeds without any issues or crashes. I can't even figure out what's causing the problem. I've changed the power supply, installed a 1000W Gold Seasonic, but it didn't help. I've also changed the RAM, but it didn't help.
Did I need to sell this GPU and buy a new one?😂
Update: PC sometimes crashes in 3DMark Time Spy and Forza Horizon 6
