CPU power settings

[Exarkun631]

I for the life of me cannot remember how to configure CPU in UEFI to draw minumal power when idle or low power tasks like web, youtube, etc and max/OC when utilizing more demanding programs or playing games.  Right now I am running an AMD Ryzen 7 5800X on a ASUS B550 ROG wifi II.  I think it has something to do with the offset values +/- in UEFI but I recenlty fried by X370 MB and I'm a little leary to mess about.  In windows I changed the minimum power state to 10% and max to 100% but it didn't result and any change as per task mtg.  At 1-5% usage the CPU clocks remain at or above base speeds 3.8 ghz.  Advise?

Ryzen has a "race to halt" approach to power savings, so it will always appear to be above base clock even at idle.

 

Any manual OC on AM4 chips disable downclocking in my experience, so your best bet is just to ensure C-states are enabled and turbo mode is configured correctly.
