    Exclamation My 2nd attempt with E6400 OC :(

    Hey all,

    At this point I'm not sure what to do or if there is even a problem. I set my overclock from the stock 2.13ghz to 3.2ghz. The multiplier is 8 x 400 which should put me at 3.2ghz. Anyways to help figure out things here is what the MB Intelligent Tweaker (M.I.T.) is set for on my Gigabyte GA-965G-DSE motherboard, I also have Mushkin DDR2 PC2-6400 800mhz memory (2 1gb sticks).

    Robust Graphics Booster (Auto)
    CPU Clock Ratio (8x)
    CPU Host Clock Control (Disabled)
    CPU Host Frequency (400mhz)
    PCI Express Frequency (100mhz)
    C.I.A.2 (Disabled)
    System Memory Mulitplier (2.00)
    Memory Frequency *this is what confuses me it shows 800mhz and 533mhz in that order

    High speed DRAM DLL Settings (Option 1)
    DRAM Timing Selectable (Manual)
    CAS (5)
    RAS to CAS (5)
    RAS Precharge (5)
    Precharge Dleay tRAS ** it shows two different numbers on the left kind of greyed out it shows 18 on the right 15 (15 is what I had set for the OC)

    ACT to ACT Delay tRRD (3)
    Write to Read Delay (3)
    Write to Precharge Delay (6)
    Refresh to ACT Delay (28)
    Read to Precharge Delay (3)

    Then a big Red warning which looks like this ****System Voltage NOT Optimized*** which pops up when System Voltage Control is set to Manual

    DDR2 OverVoltage (+.3V)
    PCI-E OverVoltage (Normal)
    FSB OverVoltage (Normal)
    CPU Voltage (Increased from 1.31250v to 1.42500v)

    This is my bios I know its alot to look at. Now when I boot into Windows and go to my computer > properties and it shows my E6400 still at 2.13ghz instead of 3.2ghz I'm confused. When I launch Prime95 and it shows my CPU at 2.13ghz instead of 3.2ghz I'm just baffled.

    Can anyone figure out what my issue is so I can fix it cause I haven't a clue.

    Sorry for the wall of text and I thank you for any info you can share.

    You'll find that the reason you're getting a lowered cpu GHz is Intel Speed Step, it kicks in when the processor is idle to reduce power consumption and heat. Start a programme like Orthos or whatever you use for stability testing then check the cpu speed, it should be reading 3.2GHz

    EDIT: That voltage seems awfully high for that oc, try lowering it and running Orthos (or similar) to check for stability if all is good lower it one more setting etc until Orthos fails to run, when you have the bottom voltage increase it up one and you should be stable.

    Anything above 2.4ghz overclock and my pc freaks out and resets the BIOS. In POST It will show 2.13ghz @ 8 x 233mhz

    I must have read your op before my morning coffee, I misread it horribly.

    Try asking in the Gigabyte forum, I'm not too familiar with their bioses.

    As to the ram, I assume you selected 800MHz?

    You are hitting F10 (or whatever your bios uses) to save changes and exit yeah?

    I'm looking for overclock settings to make my goal of 3.2ghz not 2.4ghz I'm not sure what the mobo forum will do for that.
