Yep i went back to auto and i guess it's suppose to be :
1 active core : 47
2 cores: 46
and all is fine, i don't see any difference in fps.. temps dropped a little but not that much actually, 60 to 62c in game
Well i came back to stock profile not OC and no issues anymore, runs fine and no crash :) Not even a difference in FPS actually.. but i'm gaming at 1440p so i guess going from stock to 4.8 is negligeable in terms of FPS right?
