My 2600x with PBO enabled for some reason likes to keep one core at around 4.2Ghz with voltage jumping from 0.9 to 1.48 all the time when idle.
This results in having 50-60C temp in idle which is strange to say the least. Is there a way to force-disable PBO outside of games?
With PBO completely disabled I got normal 35-40C when idle, plus in idle CPU downclocks to normal ~2.5Ghz.
I have Deepcool Gammaxx 400 btw (130TDP). Also tried different power plans.
Here are the examples:
Power saving, PBO.
Balanced, no PBO. Idle 35C.
Balanced, PBO. Idle 45-62C.
Ryzen Balanced and High Performance plans are exactly like Balanced.
