EDIT: Tentative solution: CoreCtrl

CoreCtrl allowed me to underclock my Radeon 5600XT GPU (currently set values to GPU 800MHz and memory set to 500MHz). I say "tentative" because this problem has been persistent for years, but I've been running Cyberpunk for 1 hour at 60FPS on High settings (and mostly 60FPS on Ultra, but I had some FPS drops). Even if this solution isn't 100% perfect, I think some combination of changing the GPU values is probably going to make my rig much more functional.

I found CoreCtrl based on a Reddit thread last night but didn't have time to test it until this evening after work. Seems to have made a world of a difference.

Yeah I've tried just about every feasible kernel parameter for amdgpu module, updated my kernel, to 6.2 on Linux Mint, and I've tried several different BIOS settings. My system runs everything reasonably. Even Cyberpunk 2077 is generally at 60FPS. But after about 5minutes of gaming on Cyberpunk 2077, it crashes. Other games last longer, which is why I use Cyberpunk 2077 to stress test my system.

These are my system specs:

• PSU: 850 Watt 80 PLUS Gold Fully Modular ATX
• CPU: AMD Ryzen 7 2700 Eight-Core Processor × 8
• GPU: Radeon 5600XT
• RAM: G-SKill DDR4-3600 CL16-19-19-39 1.35V (2x16GB = 32GB total system memory)
• SSD: Samsung (MZ-V7E500BW) 970 EVO SSD 500GB - M.2 NVMe
• MOBO: Asus x470 Pro
• Other: TP-Link AC1200 PCIe WiFi Card for PC (Archer T5E) - Bluetooth 4.2, Dual Band Wireless Network Card installed in PCIEx1_3 which seems like it could be a variable I should remove, but I've tried removing it and didn't see any changes in behavior. I've tried various PCIEx1_* slots with similar results.

I don't really see where I might be going wrong here. I bought this all ~4 years ago and I've always had these intermittent crashes. It's admittedly worse on Linux, but it still occurred on Windows.

Anyways, I spent about 5 hours last night reading bug forums, testing various amdgpu mod parameters, settings in my BIOS, and even re-configuring my fans to provide (potentially) more optimal cooling. None of this really made a difference. I run two 1080p monitors (not exactly breaking the bank here). I had a lot of hope regarding one forum about ring gfx_1.0.0 errors related to how AMD reads the GPU in Linux. My graphics card is detected as: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] and apparently some machines used to accidentally use the total allocated memory for 5700XT instead of the 5600XT. This resulted in some form of corrupt memory allocation. That sort of behavior would make sense for my system since it runs well, but just fails suddenly.

Other errors I've seen are:

^ These are all errors which occurred from various tests of amdgpu module settings and/or BIOS settings. The common thread is some form of ring XXXX timeout.

These two threads seemed like my best chance, but their proposed solutions didn't help:
