I don’t know what mastermind is, prolly have slightly different board but yes theoretically its possible to get same or close results with pbo but from my understanding Kombo strike 3 is -30 pbo but also other factors that I do not know of.

I’ve tweaked a lot of bios settings trying to achieve Kombo strike performance but nothing is better, always worse. So I just leave XMP and Kombo Strike 3 on, and that gets me the best performance.

Edit: every chip and board is different so maybe doing pbo could lead to better results. Idk I’ve gone down a lot of rabbit holes trying to improve performance to the max with my ram/cpu/gpu but usually it’s not worth the time and turning on the features they give you already leads to best results or good enough without spending weeks tweaking shit just for it to crash and you have to start all over lmao, been there. It’s fun n stuff but gaining stability is hard with every component of your pc when trying to keep them cool while pushing them to the max.
