[AB350 Pro4] Overclocking via Pstates

Hello,

I don't understand what you mean with " lower power by default ".

SiX-P4cK, I have the ASRock X370 Killer SLI/ac board, and I was able to get a lower P-State working. Our boards have different UEFI/BIOS, so I cannot guarantee this will work on your board.

You seem to be using the standard Windows Balanced Power Plan, and not the Ryzen Balanced Power Plan, right? When I used the Ryzen Balanced Power Plan, my method did NOT work.

I just got the multiple PState levels to work for the first time, so I'm still learning how to use them.

This is using the Windows Balanced Power Plan, default Processor settings.

Questions:

Do you have Cool N Quiet enabled? Do you have Global C States enabled?

I have both of those options enabled.

I have my CPU OC to 3.925GHz configured in the OC Tweaker screen, not just in the Custom Pstates screen. CPU Frequency and Voltage Change is set to Manual.

Here's a screenshot of the Custom Core Pstates screen:



Custom Pstate0 is my OC. I have the same frequency and VCore set in the OC Tweaker screen. I'm using Offset Voltage mode, Offset Voltage value set to Auto.

Notice that Custom Pstate1 is set to Auto.

Custom Pstate2, set to Custom, is really the default/automatic Pstate2 that the UEFI provides.

Task Manager is not the best way to monitor the changes in processor speed, but since you used it in your example, I will too:



Notice my Maximum speed is 3.92 GHz. This is a better example of the processor cores at different speeds:



As I said, this is my first success experimenting with Pstates. I have much more experimenting and testing to do. I suggest you try a lower frequency than 3.8GHz for the lower Pstate, at least as a test until you can control it as you want it to work.

Did you have any success?
