" rel="nofollow - 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?

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

PBO has been dropped by AMD for AM4 so you will needto stick with 4.71 forever. Atleast that is not AsRock fault.

ASUS, Gigabyte and MSI forums are playing with Ryzen+ & PBO/XFR2 on X370 mobos. Do we have any official statement from ASRock or AMD?
