I mainly use AI tweaker. I'm old school, don't use Ryzen Master or anything from OS to overclock.
AMD CBS, rarely need to use. (turn on virtualisation, think it was here)
AMD overclocking, very rarely use.
PBO is AMD overclocking thing and is the oldest method.
PCO is AMD overclocking thing, similar in function to Ryzen Clock Tuner.
Best off searching for few articles on PBO & PCO and learning what use it for.
PBO
