  • 2500k overclock

    System is as below in sig.

    To cut it short.

    Asrock p67 auto overclocks.
    4.0-4.4 nps 1.2-1.33v
    4.6 works all the time under tests.base 1.37,turbo up to 1.44v
    4.8 works all the time with 1.39-1.4v base and turbo up to 1.48v. IT DOES NEED llc 3 for 100% stability.

    5.0 needs manual input of 1.43v and offset +.10v and pll overvolt enable..+ all fans running full on for testing ,ie getting to intel max v of 1.52V.
    Temps on air are reaching 80-85 so its not really viable.

    The above is about what ive seen for most p67 boards,asus,mfi and gigabyte included.
    An exception is "raider" a some time poster here who seems to have a very good chip .

    Has anyone achieved better results(maintaining full multiplier in testing) at lower temps/different bios /uefi settings?(on air)?.

    nb Ive been using base clock for multiplier of 100.2 or 100.5.
