After some advice, I understood that over 1.325v on all cores full load for zen 2 is not safe. I have manually override to 1.325 and set the clock speed at 4.1GHZ. I have played a couple of hours of BFV and it is stable. I have ran the AIDA64 Extreme stability test on CPU/FPU/CACHE for 20 minutes and no problem. I am running an ARCTIC freezer 34 DUO (Temp max 83C). However prime95 small fft crashes instantly at start. I have researched that real life usage will never reach P95 loads anyway so just ignore it? Maybe some gaming on BFV, some other AAA titles and some video encoding/rendering.
