  1. Hi guys,I have this system:
    Cpu - core 2 Quad Q 9550 2.83 Ghz.(stock)
    M/B - Asus P5Q SE2 Chipset p45
    Graphic card Nvidia Geforce 9800GT 1024 MB
    Memory - OSZ 2048 Mb PC2 6400 (400 mhz) Nvidia SLI redy 2 -2GB (total 4 gb)
    Watercooler -Corsair H50
    Hard drive - WD 750Gb
    Ok now the setting I,ve trying:

    FSB 426
    Cpu clock 3.43 Ghz ,
    Voltage 1.336 V
    memory voltage 2.1 V, mem timing 5:4:4:15 ,so i got 1:1 FSB:Dram
    And all rest is Auto.

    It works kind of unstable,and sometimes i got crashes, it's just throw me to the windows with some funy pixel (a lot of Colors) screen ,when i playing the online game such as ModernWarefare 2.
    Is any one know the best setting for this Hardware ? and How Far I can go with that?

    make sure you have CPU and PCIE spead spectrums disabled in your bios it helps with overclocking also turn of intel speedstep and anything that throttles your cpu. next you need more voltage my good sir try 1.375 that is a good round voltage for that overclock.
