Hello,
when i upgraded my ryzen 2400g to 3600, my system went unstable with random freezes (memory management bsod on windows). So I tinkered a lot with bios settings until i found that disabling c-states fixes the problem.

Is then the motherboard or cpu being faulty? There was also no issue when i used the cpu on an older gaming itx b350, even when c-states were set to auto.

Disabling C states help with memory compatibility. Perhaps you have a mmemory problem with the new CPU in this board.

The Fatality B450 Gaming itx/ac is sh*t in memory compatibility.

Perhaps that is the problem.

I dont mind having it disabled unless it provides some penalties to performance and stuff. What i don't like is that it was enabled by default even if it can cause stability problems
