ryzen 7 2700 won't underclock while idle

Hello, i need some help to figure out why my cpu constantly running at 3.2-3.3ghz while idle, both amd balanced power plan and windows balanced plan with a minimum processor state at 5% do nothing at all, both of them behave like im using the high performance plan.

 

Wierd thing is, that when i set the minimum processor state from high performance plan down to 20% then the cpu will downclock down to 1.5ghz and 0.89V, but its completly unstable, with the cpu boosting to 3.6-4.1ghz all the time while idle, voltage spikes from 0.89v to 1.44v and temps fluctuate from ~30c to ~45c every couple seconds causing AIO fans to ramp up all the time.

 

Already tried to load optimize default settings from bios, enable / disable C-state and amd cool' n quiet and change to p0/1/2, i didnt mess with nothing else, everything is set on auto. Also cpu running at stock speeds.

Bios (f51), windows and chipset (2.01.15.2138) drivers are all updated to latest. Tried also to reinstall chipset drivers.

 

ryzen 7 2700, 16gb ram 3000mhz, b450 aorus elite, 750w psu.

Why are you so concerned about 2w~3w more consumption due to the higher clock? it really changes nothing.

Because it completely looses the ability of boosting to 4.1ghz single core if all of them running at 3.3ghz, with the maximum core boost dropping to 3.5ghz.

It only matters while playing some really old games which they use a single thread of the cpu.
