ASUS, Gigabyte and MSI forums are playing with Ryzen+ & PBO/XFR2 on X370 mobos.

Do we have any official statement from ASRock or AMD?

Atleast that is not AsRock fault.

Ok, PBO works on beta 4.71, it even allows to set manual wats and amps but EDC limited by 168A

Hello, i have ryzen 2700x and Asrock x370 killer sli.

When i activate XFR (PBO) in AMD CBS section of bios - the computer no longer boots.
It reboots, slows down coolers and that's it. No image on monitor. The bios is 4.8.
Does anyone have the same problem?
