Useful config data (not in the log) is as follows:
1. TUF GAMING X670E-PLUS WIFI Rev 1.xx
2. Microsoft Windows 11 Pro 10.0.26200
3. Bios Version 3854
4. RAM is 32 GB of Corsair Vengeance DDR5

Edit: FAH isn't allowing me to copy-paste my entire log. Had to copy-paste in snippets
Edit 2: Executed both a Windows Memory Test + sfc /scannow and both passed without error
Edit 3: Also reinstalled FAH 8.5.5 and completed latest windows update. No dice.

Windows memory tester isn't very reliable. Run memtest86 from a boot drive. Go from there.

[muziqaz]

Your PC is unstable.
Memtest86 for starters, of that is too hard, run y-cruncher stress test overnight

[BB63]

Passed Memtest86 during the night.
Will start ycruncher stress test while my family drags me out for the day

Also (to my knowledge) FAH is the only app that I use that results in these memory errors. I hope the stress test reveals something

[muziqaz]

It is possible you have latest AMD Drivers installed (26.5.2) installed which nuked OpenCL as well as HIP. Roll back to 26.5.1 to get back the functionality in FAH

[BB63]

… what.

I’m looking at the adrenaline driver notes and I don’t see anything like that https://www.amd.com/en/resources/suppor ... 6-5-2.html

Edit: Will give the rollback a try when I get home.
Wtf AMD

[muziqaz]

They know about this, and I think they mention Blender being messed up
