hey guys, i got a question, first i got 4ghz 14 hours prime stable with 1.375v vcore , qpi/vtt 1.315v

then i flashed to f4n and i needed more vcore so i flashed back to f4k and i still needed more vcore so i ended up doing 21 hours of prime @ 4ghz @ 1.395v vcore

anyway i was folding with 2 smp clients and when i got up this morning the pc had crashed, but when it crashes it doesnt just restart , it kinda just hangs and my gpu fan revs flat out until i push the restart button,

anyone else getting that when it crashes ?

and why is it crashing after 21 hours of prime small ftt, i also ran memtest86 ver 2.10 to test memory and that was ok
