man, this thing is freaking me out, from f3 bios i flashed to f4k, got it stable @ 4ghz @ 1.375v vcore and qpi/vtt 1.315v, also got 4.1ghz stable , 4.137ghz stable, and then 4.2ghz crashed after 8 hours 38 mins of prime, then i flashed to f4n , and i couldnt get it stable , or it needed more vcore then with f4k,

now i went back to f4k and it needs more vcore than before to get stable , wtf is going on

so now ive come back to f3 just running this again and then i might go back to f4k again

is it posible i stufft up my cpu ?
