under-clock... setting cpu maximum processor state to 10% ryzen 3600

[killster1]

So no issues with browsing / downloading / playback of h265 uhd, power plan to use maximum 10% frequency, so it runs 2.2ghz @.9v temps are nice and low @30c doesn't get past 35c usually. When i want to do something more extreme i set it to 100% and if it was winter i wouldn't mind setting it to 100% but seems weird to have all this boosting / volts jumping around.

So my question is, whats the best way to go about this? bios setting or is just using the power plan settings to change it inside windows is fine? (i like not having to go into bios to change it back to normal silly boosting 4ghz. Maybe i should just disable the boosting in the bios? x470 tachi ultimate.

At that voltage, you should be running more like 3.0Ghz. I'm at 2.8ghz @ .894v with a max package wattage pull of 38.15w and cores at only 24.14w. Can run 3.0ghz with 1v even.
In the realm of passive cooing. Let me mention that I do have SMT turned off to help lower current draw.

I set mine up manually in bios with ROG B450-I gaming and LLC set to level 1. If you need any screen shots, let me know.

yes sure id take a look at the bios settings you got going, see how good my silicon is on my chip and if i can match it. I guess i can save the diff bios profiles to make switching them easier. Thanks

Just switch to the power save profile in windows to cut power use and ryzen performance mode while gaming.

well the other guy already said his bios settings will give me a better volt/ghz ratio then windows is giving me. (thats what im doing already is changing power save options.................)

Cool , you have options then I go easy none reboot personally but another way is using profiles manually set and saved in ryzen master, it would reboot if switching between PBO off/on, if it were used.

Ok no problem. At work so later today Ill take some screen shots of the bios.
You actually dont have to change much. When setting the multi to manual setting, it shuts off boosting automatically.

I have the option to manually set the volatage (without offset). When using offset, you are going to subtract from the highest pstate voltage.
To find out your processor pstate voltage, go to cpuz about tab and save txt. Open the txt and scroll down to listed pstates.
This will give you an approximate idea of where your voltage and clocks should could be at.

You should be able to run a lower voltage than my 2700x, this chip leaks a little bit.

OK here's those screen shots I promised ya!
I do have PBO disabled because I simply just don't ever use it.
