I have a ryzen 5 1600x running on a asus crosshair 6 hero motherboad and when playing games like bf1 i have a sudden freeze of game and after few seconds its all ok again. When i look at the hwmonitor after the freeze i see that the vcore was down to 0.628v... the same is when ysing cinebench. It freezes totaly then unfreezes ant the vcore drop is there then... i have the cpu oc'ed to 4ghz on 1.35v and until few days back everything was fine. And the hwmonitor and cpu z show at idle 1.33v sometimes it shows max 1.352v. What could be the problem of theae massive vcore drops?
