    Default Trying To get 4.3Ghz Stable in 3DMark

    Hey guys....just trying to get a 4.3Ghz run stable for 3Dmark as i am chasing 27,000 3DMark Pts

    My Setup

    i7 920
    Gigabyte X58-UD5 w/ F5d bios
    3x1GB G.Skill 1600Mhz 9-9-9-24-2T
    HD4870X2
    1000W Antec Quattro

    Plenty of cooling (HSF is TRUE 120 w/ 3 Fans)

    BIOS Settings

    CPU - 4100Mhz (w/ 21x Multi = 4300Mhz)
    BCLK - 205
    RAM Clock - 1640Mhz
    HT - On
    Turbo - On
    RAM Timings - 9-9-9-24 2T (all set manually)
    QPI Multi - x36
    RAM Multi - x8
    Uncore Multi - x17

    Voltages

    CPU - 1.55V (pencil modded so 1.525 REAL)
    QPI - 1.455V
    IOH - 1.2V
    RAM - 1.7V
    CPU PLL - 1.92V
    QPI PLL - 1.3V

    everything else auto.

    Almost gets into Windows but crash this

    Machine Check Exception - Wikipedia, the free encyclopedia

    Any input on getting it stable enough for just a 3DMark run would be awesome :)

    After that i will go back to 4.0Ghz :)

    Did you try Performance enhance on standard? Turbo off I think it what you have set on now right?

    Performance enhance on standard as per normal. Turbo off for 4.00ghz clock, but enabled for 4.3ghz run, as bclk @215 is pushing limits of the board.
