    Can I expect my chip to live another couple of years @ 4ghz with 1.4v in BIOS? CPU-Z reads 1.382v at full load and 1.376v idle.

    Is it gonna fry? My temps seem nice 38-40ºC idle - 58-60ºC load.

    I know that overvolting always reduces a chip's life. But if we're talking of a life expectancy reduction from 10 to 5 years, I can live with that :)

    My chip shouldn't fail or anytime soon with these volts, right?

    BTW, other volts are:

    CPU PLL: 1.56v

    FSB Termination volt (VTT): 1.28v

    GTL Ref: 0.63x (no matter how much i read, i can't understand what this does lol. But hey, Science is not my field! :p)

    NB: 1.26v

    Should be fine, iirc 1.45v is the max you want to go with for 45nm

    Over 1.4 is where Intel's 45nm seem to get sensitive. You are below that, so you should be just fine.

    My E8400 C0 is very voltage hungry as well and very similar to your chip. CPU-Z says 1.384 volts at idle and 1.400 volts at full load for Prime stability. My second motherboard pencil mod was excessive but the results are perfect. Much better than vdroop. :D

    It's been very stable at this setting with no noticeable change in performance for months. It needed slightly less voltage when I first got it but after lots of abuse, it seems to have settled in at the above settings and has been stable ever since. This seems to be normal sort of break in of these chips. I think as long as you keep the core voltage under 1.40 volts that you'll be OK for a while.
