Just avoid the manual OC and use PBO with an offset. Little to be gained these days with OCing a CPU, other than more money on electricity
You try telling DCS VR that
PBO will only get it to 4.05-4.1 at best, compared to 4.3 that equates to a substantial drop in performance.
that must have been a bug, no way you got max temps of 66c in summer with an OC, a stock 3600 would be over 66c in prime
It was the AVX instructions in prime95, disable them and it's rock solid at peaks at about 58-60°C on normal workloads, prime95 got it up to 66°C I think.
