    my mate has been able to get his pc fully stable @ 4.0ghz using all voltage settings as auto, is this bad? I didnt think it was even possible..

    GB UD5
    i7-930
    2000mhz ddr3 @ 1600mhz

    Very possible but not good, I'd ;ike to see what voltages the mobo is setting as auto, they will be way too high, set them manually and lower them till you lose stability and then increase one notch and stress test for stability, the temps should lower dramatically:thumbup: and life expectancy will increase

    weird thing is he currently only gets 49 degrees on prime95 WTF i get higher idle temps @ 3.8ghz and I hit 78 degrees on prime95 :S

    He has a h70 stock fans, I got h50 push/pull with noctuas

    edit: he is running 1.38 volts on auto :S and his cpu actually hits mid 70's he was reading me wrong temp

    edit 2: he only seems to have 2 cores??? hw mon and prime95 r only showing 2 cores not 4???

    Certain that he using a motherboard utility like easy tune to look at the temps, normally the temps are around 15-20 degrees higher than what easy tune says.

    his temps are actually 70 ish during prime95.. so thats good considering its @ 1.39 volts jeeeeeez is that fry territory?

    for some reason msconfig>boot>advanced has only 4 processors selected instead of 8 (or even better not being selected) weird....

    told him to try a manual vcore @ 1.32

    i7 950
    2000mhz patriot viper ddr3 @1700mhz
    All auto except for CPU which is on normal, ram on 1.64. temps are low 70s in prime.

    He wont be running HT then, that produces a ton of heat.

    I've overclocked my PC to 3.8GHz but only reaches up to 2.54GHz underload. What the?

    Cant be turbo, have you disabled all of the energy saver technologies? Thats a start I guess.

    Seems to be a good way to make lots of heat and to see the Gflops.

    Though you do need longer in Prime too - I got about 6 hours into it and a worker stopped due to incorrect rounding.

    I thought... bahhh that's long enough but then I had BSOD the same day a few hours later! Time for more testing.

    I've been using the 3 step overcocking guide - it's really good.

    Those voltages look pretty sweet mate, very similar to mine.
    as for your Prime shitting it self after 6 hours, notice your QPI/VTT was at 1.19v, Try raising it a few volts and see how you go.

    I've been told that the 950 have an older intergraded memory controller and is a little more voltage hungry then the 930/960 range

    With mine, i needed atleast 1.325vtt to get a long term stable o/c.

    Yeah cheers that was it. I went up two notches to 1.235 OPI/VTT.

    24/7 OC is both cool and stable :)

    I have had my 920 running at 4.08GHz but that ended up being a bit too toasty as the volts required were around 1.3-1.35+ on the Vcore. So I lowered it to 3.8GHz which can run at 1.168-1.184 (1.2 in BIOS) and at about 10-15 deg lower at load :). Very happy with this OC at very low volts :leet:. (Specs in sig).
