Too many volts?

ShadowFold · Feb 22, 2009, 09:47 PM

Can too many volts make an OC unstable? I've never tried this myself, just wondering.

Yes, on my Q6600 too much voltage would make the machine not even POST, even at completely stable clock speeds.

Anything over 1.8v for my best Q6600 would render the rig a hunk a metal. It could do 4.3 at 1.75v & it was rock solid even for gaming. It wasn't stable at any clk over that no matter how high I pushed the volt until 1.8 where it wouldn't POST anymore.

when i set my CPU over 1.7v it won't boot it BSOD when loading to windows ever at stock speeds even with temps being around 40c.So yes i would think it is possible

A hundred-million year old Vapochill. I had to make a custom bracket for it & seal the DFI board. I don't feel like do all of that crap with the i7, not that it needs it anyway. I can max it out on water. I just need the power to do it. My 1000W'er can't take it above 4.4 with all the junk I have in the rig.
