Thanks for all the answers guys! It could probably be the chip, but we know that 4ways are the best overclockers so far. And the E760 is getting pretty old, and I can sell it with good benefit without loosing too much on it.
Yes, I always set the board ready for sub zero cooling with bios options and X-cool.
But is there any new 4 way board on its way from EVGA? Cause I don't want to buy a brand new Mobo for a lot of $$$ and they release a new one two weeks after.
