What is safe voltage for 45nm Dual core on DICE?
I want to know if there is a limit to how high I should push these 45nm Dual Core's on DICE. I know I see 1.8v+ on some, but thats usually LN2.
I want the chips to last for a little bit at least, like 20 hours of benching at a minimum.

Max on air is usually ~1.36v
I would not pump more then 1.6v on DICE

I believe it's safe up to 1,8v, the same as when using LN2. On 1,6v some people are benching on air/water
 My e8400 does 4,7ghz <1,5v on air and that's safe if temps are below <70C. But if chip is scalling well I usually pump more voltage...

I did several runs on a E8600 at around 1.8, when I went much over that it died on me after a few day.
A E7200 died on me at only around 1.7 - 1.8 v-core after several runs. So I don't really know if it was just the v-core or doing multiple runs on them that killed them.
