    [SOLVED] Which is more "healthy" for Ryzen: manual vs PBO OC?

    So i have an R5 3600 and i've read in a few threads that ~1.3V isn't that healthy for Ryzen CPUs in terms of longevity. So here is 2 option: Manual: 4.2GHz all-core (12 threads) at 1.315V PBO: +200MHz Based on my tests the 4.2GHz all-core performs better in most of the games(+raw performance)...

    Hi! I recently got new mobo and CPU, Asus TUF B450-PRO GAMING + Ryzen 7 2700. So I wanted to improve on perfomance, but I can't find anywhere in BIOS how to enable Precision Boost. All I could find was PBO, but the PB technology itself no. I have the newest BIOS (1807 - 09/12/2019). All I...
