It goes the cpu go from 3.9 or (4.0 with oc)to 600mhz for about 1or 2 seconds completing killing the fps in dayz (I could not reproduce outside the game I think)
It only happens when I oc the gpu past 1250mhz (even in 1300mhz) (I tried to rise the voltage as well)
I have a b350 gigabyte gaming (the normal one not the 3)
Memória Corsair Vengeance LPX 8GB (2x4GB) 3200Mhz cl 16
using the latest bios f22
I could not find anything about anywhere(maybe because dayz is so low in popularity)
