Looking to overclock my CPU. can i get any help with it? (like program and what to oc it to) thanks
PBO is enabled through either RyzenMaster program (available on AMD website) or BIOS of your motherboard. BIOS is preferred, but RM is a good way to experiment.
The general method with 2nd gen is to turn PBO on, set to manual, slide the EDC, TDC and PPT sliders to max and undervolt the core voltage as much as possible (until it becomes unstable, then back up a notch) using negative offsets. That's the general method, tweaking of course often helps.
While PBO is reputed to work well on 2700X CPU's, 2700's aren't graced with as much boosting margin and don't usually benefit as well. You're often better off fixing an overclock...
