    vvt @ 1.34
    ref 1 @ .85
    ref 2 @ .88

    mch up to 1.34
    and the gflops are up to where they should be but still failed on second run
    is mobo temp tmpin2 a problem? ( would that be north bridge )

    Are those reference values at 1.2v VTT or for the targer 1.34v?
    Doesn't this board has a massive HS for the NB and everything else?
    Try some more vcore.

    Try MCH Reference first.
    To adjust reference voltage:
    1. Set VTT to 1.3v.
    2. Set the reference to it's desired value.
    3. Set VTT back to it's original value (reference voltages will scale with VTT)

    Try 1 to 4 ticks above and below the default reference value (the value on the left)
    He ment set vtt to 1.2 default then make the adjustment then set vtt back to where it was.

    those refs were 60% and 64% of vtt as per bios template.... and were within 4 clicks up from stock so thought i'd give them a shot...
    played bfbc2 all night then a bsod in the last round ( 0x00000124 ) made me reset back to 4ghz.. then had a giggle and with the 4ghz settings clicked pci up to 102 and set ram at 5-7-5-16 @ 1583mhz, not only did it boot but pulled 22023 on 3dmark before bsod ( ram timings )

    anyway on the refs i'm a little confused:-
    set vtt mobo stock
    set refs mobo stock
    then up vtt ???

    is that right so when i change vtt the refs change but stay within x%?

    yes this mobo has the big nb heatsink and whole system is watercooled. am i being too soft with the voltages?

    Precisly. Some motherboards has it as percent so you don't need to change VTT to know what you are doing.

    0x00000124 means more Vtt, but that could be skewed by your changing of the ref values.

    If you are not over 450-500 FSB you should need to adjust CPU ref's

    I keep having issues with memory speeds while oc'ing this board, is there something magical about the 1600mhz memory speed? Is it the point that sends too much info down the bus and it cries enough?
