    Default UD3P and E8400 need help

    I need some suggestion on my system

    E8400 + UD3P running best on overclock at 4GHz (800x5) with original cooler

    It look like need some optimized and fine tune for stable.

    Do you think CPU Vcore and CPU Termination is too high?

    If I set lower it could not enter Windows :(

    Setting in BIOS

    Motherboard Voltage Control
    CPU
    Load-Line Calibration..................: [Disabled]
    CPU Vcore..............................: 1.400V
    CPU Termination........................: 1.580V
    CPU PLL................................: 1.500V
    CPU Reference..........................: 0.760V [AUTO]

    Your VTT(CPU termination) is way too high!!!!!

    Take it off of Auto

    If you have an E0 E8400 you likely can get away with much less Vcore for that same 4Ghz.

    On mine it runs 3780Mhz(420x9) on stock 1.25 Vcore in bios w/ LLC enabled.


    A starting point would be to take those settings from ET6, and put them in bios, except for that VTT as that is way too high, 1.30v is prob even high for that clock speed.

    Remember that ET6 shows the reference voltage a little strange till you understand how it works. How it works is it is showing you the reference voltages as if VTT was set to default 1.20v, then change the VTT and it will adjust the references.

    For a stock cooler I think your temps are going to be too high also when under 100% load, since your idling at 46C.

    You really should shoot for 3.6Ghz 1st on stock voltages and see your load temps. Then go a little higher at a time and make sure they dont go over 70C max. Personally I dont like going over 60C as I plan to keep my CPU for a couple years
