    hey thanks alot!!
    just an update... i just ran memtest for one hour with no errors with my previous settings. thats at two instances of 2045 mb.
    ill try your recommendations now to see if prime will go for an hour..
    wish me luck!!

    btw ... theres alot or recommendations you got there. you think i should change them all at once and then try it. or should i do one at a time?

    Anytime man, I am here to help!

    I suggest setting them all at once, then you can lower/tweak later on. Good luck with the tweaking and testing, it can take some time just don't let it frustrate you!

    progress report....
    since memtest ran good for an hour im thinking its not to do with the ram. so im leaving dram and all the timings as is and focusing on the other voltages.
    first i started with your suggestion about the qpivtt being too high and strangely enough i was getting 00000124 bsods meaning incorrect qpivtt!!
    i did lower it a bit to 1.435 and got 30 mins prime however any more lowering resulted in less prime.
    so with 1.435 ive been trying the other voltages one at a time and it looks like so far even the slightest increase gives a no go. heres where im at so far...
    ioh core 1.2............9 mins
    cpu pll 1.84............<9 mins
    pcie 1.54 .............. <7mins

    now trying qpipll 1.18

    dont give up on me k..... out of 5 different websites ive posted this on youre the only person willing to give me a hand. youre the bomb dooood thanks so much wish i could buy you a beer to say thanks...

    thanks for the help bud...
    my post there with all my settings is what im using as my baseline.
    it took me 3 months to figure out that overclock and finally i found that it was the ioh core that was being set way too high on auto and that 1.18 was the magic number to get it going.
    my i7 965 will not run prime with any less than 1.46875 on the vcore for an overclock of 4.2 with HT.

    So how are you coming along? You may need a higher QPI/Vtt, I likely just asked and/or suggested you may be able to lower it a bit with more IOH (1.20-1.24)

    I use a lot of QPI/Vtt myself, often 1.4-1.5+ so it is fine
