why would you need to push it past 1.5 v ??
i'm at 4.1 @1.39v happy there for a while but 1.44 gets it stable at 4.3 but have to run fans at 50-60% sounds like case is taking off ..
whats your temps at 1.55 and above ?
some times they just wont do it ..
had a q6600 run at 3.85 could never get it past 4ghz no matter how much i tried ...
AMD FX 8350 5.1ghz 221x23
CROSSHAIR V bios 1703
g-skill sniper 1600@1800
What does it matter now if men believe or no?
What is to come will come. And soon you too will stand aside,
To murmur in pity that my words were true
(Cassandra, in Agamemnon by Aeschylus)
