    Default How can I overclock my system?

    Hello, i have never made overclock before, i would want to try it now with my new rig :)

    My system is:
    Gigabyte GA-EP45-UD3P (bios F5)
    Corsair Dominator PC8500 (2x2Gb)
    Intel Core2Duo E8500
    Powercolor HD4870 1Gb PCS+
    Thermalright 120 Ultra Extreme
    Corsair TX-750W
    Samsung 750Gb 32Mb 7.200rpm
    Coolermaster CM690

    How can i setup my bios to get a decent overclock with my system??? (i would like to get about 4Ghz for a 24/7 use of the pc)

    Thanks in advance :)

    U can use the same settings as i do, only lower your memory multiplier to 2.0 in stead of 2.4.
    And your processor being of better quality than mine you should be able to reach it with lower voltage.

    thanks for the reply.

    my only concern is that our motherboards are not the same...

    If your motherboard doesn't like 500 fsb, try a lower fsb with a higer multiplier, like 470 x 8.5 or 444 x 9 or even 421 x 9.5
    The highest fsb should give you the fastest system tho, at even processor speeds
