    Question My First Overclock

    Hello Everyone, I just performed my first oc and was wondering if you guys can lend a hand. I been at this for two days now off and on, and i just cant seem to get the setting correct two get this chip stable at 4.3Ghz or 4.2.

    Here is a screenshot when i had it at 4.1Ghz, but was getting an error from orthos that read "FATAL ERROR: Rounding was 0.5, expected less than 0.4"

    The chip is an E8500 and the board is a GIGABYTE GA-EP45-UD3R

    Now im try for 4.22 with the following setting and the machine will either bsod, or just reboot. Any help would be great, thank you.

    Try For 4.22Ghz Here:

    CPU clock ratio: 9x
    Fine CPU Clock Ratio [+0.5]
    CPU Host Frequency (Mhz) [445]
    PCI Express Frequency (Mhz) [100]

    Performance Enhance [Standard]
    System Memory Multiplier [2.00D]
    MCH Frequency Latch [Auto]

    Advance Clock Chip Control
    CPU Clock Drive [800mV]
    PCI Express Clock Drive [900mV]
    CPU Clock Skew [0ps]
    MCH Clock Skew [0ps]

    [Voltage]
    CPU Vcore=1.3625 Volts [Manual]
    CPU Termination=1.34 Volts [Manual]
    CPU PLL=1.50 Volts [Auto]
    CPU Reference=0.760 Volts [Auto]

    [MCH/ICH]
    MCH Core=1.260 Volts [Manual]
    MCH Reference=0.760 Volts [Auto]
    MCH/DRAM Reference=0.900000 Volts [Auto]

    Thumbs up Re: My First Overclock

    Thanks, after messing with this for a few days, i finally got a good test with good temps. If anyone else has an E8500 with a Gigabyte P45 UD3R board, and need a reference. This is what i used.

    Thanks for the replies, a few of the volts were way to high. I brought them down a bit, and its all good, thank you again.
