Hi all,

I updated my bios to 2412 last week, put it back on expo II and set curve optimizer per core like on old bios. (This was runnning stable on bios 1645)

It runs the cinebench23 stresstest and all 3dmark ultimate stresstests i tried no problem.

but while gaming (bg3, civ6 and starfield) i get random craches to desktop.

i tried going back to expo I, and ran my GPU at default. but the crashes continu.

Anyone got any tips on what to try next?

My system is:

MB: Asus rog strix B650-A Gaming wifi

CPU: 7600x

GPU: Sapphire Pulse 7800xt

RAM: G. Skill Flare X 32GB DDR5-6000 CL30

PSU: MSI Mag A850GL

OS: Win11pro

Update:

I fixed it.

did a DDU uninstall and reinstall... this made it much worse. civ6 crached after like 4 or 5 turns

reset the bios to default, it worked...

reset EXPII, still worked

put back my curve optimizer, didn't work

turns out for some season setting CU chances the max clock speed from 5400 to 5450..

it doesn't show the chance in bios, but in ryzen master the max clock changed

I put a negative 50 clock in bios to change it back to 5400 and now it seems stable again.
