    on a side note, always keep an eye on the temps...it's obvious that when you OC a CPU chip, naturally the temps go up.
    So very true. And It's one thing to OC to 4gig and get good temps on idle.... What about them at load?

    And when you check the load temps, run the program for more than a minute.... unless the CPU is already calling the fire department


    :)
    If i remember correctly, idle at 29-32 degrees (depends on room temps), never goes above 40 degrees at full load (3.6GHz).
    When I OC the chip to 4.05GHz, it idles at 35-40 degrees, seen it at 45-50 degrees max at full load.
    Pretty damn good I think (got to love the cooler).

    Yes, those are good temps. Mine idles between 30c and 34c. Highest temp during 6 hours of OCCT was I think 67, with 62 being about average. More than adequate since I don't do anything that remotely approaches 100% CPU usage. A Guy

    My Overclock:

    i7-930 @ 4GHz.
    vCore: 1.29
    Multipliers: 19x211 (got lower temps this way, used to have 21x but the temps was higher and required higher vCore to run stable.
    Turbo: Off
    Temps: 60-67 degrees max load under stress, rarely goes over 63-64 in gaming, which for me is ok.
    Idle: 39-43 degrees with fan on 50%
    I don't see the point in going higher, and it's not really smart either. The performance over 4GHz in games are very small. I would maybe get 5-10 fps more with 4.2GHz, and when in most games I have over 100fps what's the point?

    For a friend


    I overclocked a friend's rig. He was using a Core i7-920 in a system he built himself.

    Got it up to 4.4 GHZ on air cooling alone (using the Cooler Master Hyper 212 Plus).

    At idle, it lingers at 40-50 Celsius. Under load, it reaches 70-80 degrees celsius (under Prime95), though I got it to hit 91 one time.

    Hmm. If you want your cpu to last a bit it's not recommended to go over 80.

    What's your memory running at? Just curious.

    BTW I'm at 3.5GHz and happy with that.

    Multi 21x160 (turbo 22x160)
    Turbo on
    Vcore 1.1875
    QPI/Vtt 1.215
    Memory 8-8-8-20-1T @1600MHz @1.640v

    Idle temps 42 (CPU fan running at a quiet 890 RPM idle)
    Prime 95 Load temps 72 (CPU fan running at a quiet 1200 RPM load)

    Memory @ 1678MHz.
    But I had to raise my vCore again "sight", cause my games kept crashing to desktop with my current config, for some unknown reason.

    I lowered my OC to 3.85 GHz. Seems more stable, and vcore is much lower.
    It's weird you need so much more vcore with just 150MHz more.
    My temps are now better too.

    What QPI/Vtt voltage did/do you have?

    BTW 4gig+ is nice, if it's stable. It one thing to hit 4gig, it's another to be stable across all applications

    I have the QPI to auto.

    Yes. For some reason 4GHz runs stable with a 21 multiplier in everything, but then it gets too hot because of the voltage: 80+ degrees
    And with a 19 multiplier 4GHz runs stable with lower voltage, but then I get these game crashes after 20 minutes.
