    What settings are you trying to use? Please fill this out and I can better help. If you want, post it back twice, once with settings you used that work, and second time with settings you tried that fail >>>

    This is Just a template I use to ask people there settings, pay no attention to the numbers in it, replace with yours

    I will take it this is the settings that fail correct? OK Will post you some setting to try

    MB Intelligent Tweaker(M.I.T.)

    CPU Host Clock Control..................: [Enabled]
    CPU Host Frequency (Mhz) ............: 467Mhz
    PCI Express Frequency (Mhz) .........:102 << Sometimes helps 100-105


    Advanced Clock Control [Press Enter]
    CPU Clock Drive...........................: <<< 800
    PCI Express Clock Drive.................: <<< 900
    CPU Clock Skew (ps)....................: <<< Try 50-150ps << I'd start at 100
    MCH Clock Skew (ps)...................: <<< Try 50-250ps << I'd start with 200

    Test the above last after you try all other suggestions. I think the MCH latch and will help you for now


    DRAM Performance Control
    Performance Enhance...................: [STANDARD]
    Extreme Memory Profile (X.M.P.).....: Disabled
    (G)MCH Frequency Latch...............: [333] << if this fails try 400, but try 333 first as it works better on 1:1 Multi's
    System Memory Multiplier ..............: 2.00b
    Memory Frequency (Mhz) ..............: ??? 934 for 2.00 above

    You will need higher FSB to use a multi that will give you 1066 ^^

    Did you try the above? If not that should work when you find the right ranges from what I have set. If your cooling/CPU is stable

    That is lower then spec for the ram, so you should not have a issue with ram settings as posted above

    i set bios to defults and then set at 8.5 x 497 vcore 1.43750
    dram 2.1v cpu pll to 1.590 ram timing 5 5 5 15 Static tRead Value on chanel A and B is set to 11 ram multi is 2.00b and is at 990 - 1000 running stable

    also i h ave a 120ultra heatsink with 120mm fan so temps are around 38c underload on prime
