    @Lsdmeasap,

    Thanks for the clarification. I'm going to go ahead and make the changes and see what happens.

    Quick question: I didn't see any reference to "Load-Line Calibration" in your original suggested settings.

    My BIOS shows the following:

    ********* Motherboard Voltage Control *********
    >>>>>> CPU
    Load-Line Calibration.................: [Disabled] - Default setting

    [Disabled] is noted as "Follow Intel spec"
    [Enabled] is noted as "Improve VDroop directly"

    Should I leave this or enable it when overclocking?

    Thanks again!

    You may/should be able to lower your voltage with it enabled if you was stable before. Check with CPU-z you should now have little to none vdroop

    Hello, I am a newbie when it comes to over clocking so I began doing some research which led me to this link. Micz- has the same specs as I do so I copied his exact settings. For some reason windows will not boot for me. I don't know what to do. Can someone help me ?

    Stock voltage probably won't do, so does DRAM Voltage 1.84.
    Set clock Sckews to 0.
    Set DRAM Voltage according to manufacturer specs for DDR-1066.
    Set Advanced timings auto.
    tRD(Static tRead Value) 6 should be OK but set it to 7 for now.
    Try MCH Core 1.2-1.24v.
    Increase vcore, probably somewhere between 1.3-1.4v.
    What cooler do you have for the CPU?

    Thank You for answering, I didn't think anyone would respond after I saw what date this thread was active.
    Cooler for CPU - XIGMATEK Intel Core i7 compatible Dark Knight-S1283V REV.W with ACK-I5361 120mm Long Life Bearing CPU Cooler I7 i5 775 1155 and AMD compatible

    So this is what I changed from what I originally posted and now Windows boots but when using Prime95 for stress testing pc crashes.
    CPU Vcore 1.32500V
    MHC Core 1.240V
    DRAM Voltage 2.000V

    Do I still need to set clock skew to 0 ?
    Do I still need to Set Advanced timings auto ?
    tRD(Static tRead Value) 6 should I set it to 7 ?

    This might be a stupid question , after windows boots what should clock speed be at idle ?

    Once again I appreciate taking your time helping me.

    Yes set tRD to 7 for now, and advanced timings auto.
    More vcore try 1.4v.
    A good indication if there is enough vcore is, IBT or LinX, what core temperatures you get running prime?.
    Start with Prime95 small FFT for an hour or two then the same with larg FFT.
    Can you post screen capture for CPU-Z CPU, Motherboard, and SPD tabs?
