    Re: core i7 920 oc question

    Your actual speed is variable, since you left Intel SpeedStep on in BIOS. When idle, your multiplier is automatically throttled down to save power.
    RAWR!

    Another wise turn off the SpeedStep and your CPU will stay at fullspeed and use the power it requires to maintain your OC at 4.0ghz.

    So....

     

    I take it you should turn of SpeedStep and run a lengthy overnight OC stability test, right?  (like pi95 followed by the Intel Thermal Management tool...)

     

    And, once you are sure it is stable at 4 ghz, turn SpeedStep back on to save on power when you are not playing games.

    Yep, you're right.

     You don't have to take on the speedstep, that's totally up to you though.
