PBO 2 exhibits varying higher and lower frequencies based on the load.
PBO 2 exhibits varying higher and lower frequencies based on the load.
I had an unusual idea about combining PBO and frequency tuning. Could PBO raise my core frequency to 4850Mhz while simultaneously reducing it below 2000Mhz during light usage? Right now 'low' only reaches around 3.8GHz, so I'm curious about the limits when using all the advantages of PBO.
PBO remains stable because of its "Precision Boost Overdrive" feature, which ensures the CPU runs at maximum speed for the least effort to complete tasks quickly. It’s best to disable PBO if you prefer quieter idle clocks and fewer performance jumps.
PBO enhances performance, it's separate from clock-based methods. C states focus on saving power, you can turn them on if needed. I'm not certain if PBO functions well with C states.
Your chip handles this on its own. When you depend on Task Manager to check idle clocks, it won't work. Check HWiNFO's Sensors panel and examine the "Effective Clockspeed" area, or simply run Ryzen Master. Both will provide precise idle clock readings.
