    As soon as I overclock higher with increased voltage the temps go above 80C and I get booted out of windows. also if I set the memory to run at its correct speed of 1600 MHz that increases the temps, I have tried several different settings at 3.8GHz but none seem to work with lower temps, I keep the voltage low I have boot problems or memory dump blue screens, or booting out of windows, any suggestions would be appreciated, oh I have just read several posts about it being a nightmare to overclock the i7 920 bloomfield CO/C1 revision, is this true? thanks guys

    what cooler are you using? it depends on your chip ive had three 920's two were average and one was a golden cpu just 1.23v for 4.2ghz and 79c

    tell me your cpu voltage in the bios at stock cpu speeds

    EDIT: what i meant was set the cpu voltage to the normal setting and see how much cpu voltage is being used in the system info page

    you could try setting cpu voltage to normal

    180x21 bclk
    12x spd memory multi
    24x uncore freq
    dram 1.55v-1.65v
    qpi/vtt 1.35-1.38v
    system performance enhance to standard

    see if you have anyluck for 3.8ghz with those settings,it will be difficult with 12gb of ram compared to 6gb
