But no one else might. ::Grins.:: q6600 rated at 1.5000 volts. Cranked it to 1.81250, drooped in windows to 1.78, booted vista fine. I'm sure it would have been really stable had I wanted to test it with the cores idle at over 80... that would easily equal melt down. (Since 1.64 drooped to 1.56 fully loaded went from 58-60c idle to over 91c in 30 seconds under primes 4 core small ftts.
Going over 1.5 is safe if you pay attention to everything else as well, especially those temps!
I am the new guy, and slightly crazy... listen to me at your computers risk! Hehehe, have fun!!
