Verify that 1usmus powerplan is working.

[AndersWSP]

Running Asrock x570 Phantom Gaming 4 motherboard.

R5 3600 cpu.

 

I've been in BIOS tweaking some stuff.

Global C-state control = Enabled

Power Supply Idle Control = Low Current Idle

 

I also read somewhere that AMD PBO should be disabled, so I did that.

I can't find any other settings (CPPC, CPPC Preferred Cores, AMD Cool'n'Quiet or PPC Adjustments) anywhere in the BIOS. Certain they were present in earlier versions but not in BIOS 3.2.

 

A single thread CB R20 has the cpu boosting to 4,1~ish ghz. Not terribly impressive.

 

Is there an easy way to verify the power plan is working as intended, or am I missing something here?

Umm PBO gives more performance so you should enable it.

This tool is intended to be used on CPUs with multiple CCX like 3900X or 3950X and Threadrippers. Your CPU only has one CCX so I don't think the tool will do anything at all. You are better of with tuning the CPU manually.

turning PBO back on did nothing.

Ohh, not really evident by how much it's been hyped up but I guess it makes sense. I guess I'm going back to a manual tune.

Tried cranking the fans (still letting the CPU do it's own thing), slightly colder, but no change in clocks.
