Edit my last post i hve booted and ran prime stable @ 5ghz for 30min but @ 78 - 80c and 1.55v im not staying here
Where do Intel say 1.52v? Because I spoke to an Intel rep and they said Intel do not support voltage changes at all, let alone 1.52v and the rep would not comment on the 1.52v number.
I used their LiveChat customer support.
You can't use the tech sheet as a gauge for the maximum safe
voltages. That's like reading the tech sheet for, say, a car and figuring out that the top speed of the car is 100MPH, that doesn't mean running the car at 100MPH 24/7 is good for it. The car would probably fall to bits.
The websites I talk about are places like HardOCP, Anandtech and OverclockersUK, the last one actually sell these CPU's professionally, and they don't recommend going over 1.38v, at all, for any length of time (though, awesomely, they'll still honour warranties for burnt out chips! =D)
You also have to remember that voltage resistance decreases with clockspeed AND that yeah, you could be using LN2 and keeping temps super cool and still damage and burn out the CPU with overvoltage.
Protip: try the LinX with AVX extensions =D they really stress out SB CPU'sEdited by Viridian - 4/30/11 at 5:10am
