Check if 1usmus power plan is functioning correctly.
Using Asrock x570 Phantom Gaming 4 with a 3600 CPU in BIOS settings. Enabled power supply idle control and low current idle are active. AMD PBO is disabled per recent notes. Some earlier options like CPPC, preferred cores, or cooling tweaks seem missing now. One R20 thread shows boost to around 4.1 GHz. It might help to check the power plan status directly in BIOS or via system tools.
Turning PBO back on didn't help much. It's not clear from how much attention it's received, but it probably makes sense. I think I'll switch to a manual tuning method.
