scrooge · 05-03-2011

hello i'm realy lost on this can anyone please gave me some help with the (imc voltage)? i checked some other sites but each site gaves me a different answer.
one site says don't go over 1.22 another says you can go to 1.40 and another says it's like the north bridge on the socket 775 boards/bios.....
so whats the deal with it?

is it safe to go past 1.22 and is it just like the north bridge ?
thanks

With the i7-870, Intel's manual says that the maximum is 1.4V (above that damage), but the DC operating spec is a maximum of 1.155V, though many people run it above that.

so if i put it at say 1.34/1.36 i should be fine?

That seems kind of high. Intel says between the operating max and the absolute max, the processor lifetime will decrease, presumably from electromigration. Electromigration has an exponential dependency on heat but a square on voltage. So make sure you have good cooling and keep the voltage as low as possible. You may want to back off on the overclock a bit.

btw, I have the I5-760 which has the same Intel spec. I have mine overclocked to 3.8 GHz and my IMC is at 1.16875V and I am comfortable with that for 24x7 overclock.
