Hello,
I hope someone can help me out...my brain is burning right now.
I have a 2700x on an ASrock x470 taichi and I was wondering if Precision Boost Overdrive is active or not. After I googled for 2 Days now I want ask u guys directly.
As far as I understood...PB is a feature which is used by default. PBO is a feature which you can activate via Ryzen Master. XFR is a feature which you can activate in BIOS to support your PB.
Am I right? 
I did not find any PBO settings in BIOS (2.0) only XFR.
I hope somebody can explain this to me.

One thing I don't know, though - how it is done in ASRock BIOS? Brrrr, I still got the chills each time I hear these words. You'll have to rely on another brother to clarify this for you. Or you know, YT or Google it.
