    Evening.

    I've just bumped the QPI/Vtt to 1.3950v and I will try to run Prime95 again.

    If I start bumping up the Vcore, what QPI/Vtt value should I start with?

    Right, have been testing further by putting the QPI/Vtt settings back to 1.3150v and started slowly increasing the Vcore settings up to 1.30625v so far.

    Haven't had any luck as I am still getting errors not long after starting Prime95 (never consistent as it's either almost straight away or 10 minutes later).

    what cpu clock are you running again? 4ghz? are you setting the uncore freq to twice what your ram multiplier is then add one to it?? try with around 1.34-1.36 qpi/vtt what ram timings are you using?

    Just started another test with the following:

    3.8ghz (21 x 180 Blk)
    CPU Vcore = 1.3125v
    QPI/Vtt = 1.3150v
    Uncore = 17 (8x memory +1)

    Ram voltage = 1.66v
    Timings are 9-9-9-24 (manual)

    wouldnt it run with setting cpu voltage on normal setting?? you could try with looser timings like 9-9-9-26 or 9-9-9-28 that will help use less qpi/vtt voltage

    The system boots fine with all of the previous settings (apart from when I set the CPU Vcore to 1.18v when it BSOD within a minute of loading Windows).

    I thought that with the ram running 1440mhz @ 9-9-9-24 things wouldn't need to be lowered. Stock for the ram should be 1600mhz @ 9-9-9-24

    Still having no luck.

    Testing:
    CPU Vcore = 1.3125v
    QPI/Vtt = 1.3350v

    No worries. I'm grateful for the help.

    I'm wondering if I can't get things ok with Prime95 at 3.8ghz without going to far on the settings, maybe I should just try lowering the clock to 3.7ghz.

    were you at stock clocks before?? 3.2ghz would be a good place to start from because it will let you use 1600mhz ram speed then you can go from there
