    So nice to see you are now stable!!

    So what are you asking? You want some ram timings or .....?

    I see you are overclocking your CPU already so I just was not sure what you meant you wanted suggestions for

    I would try these for what you are running now >>>

    Robust Graphics Booster___________ [Auto]
    CPU Clock Ratio ____________ [8]
    CPU Host Clock Control_ [Enabled]
    CPU Host Frequency (MHz)__________ [444] << I think that is what you are using?
    PCI Express Frequency (Mhz)_______ [100]
    C.I.A. 2__________________________ [Disabled]
    System Memory Multiplier (SPD)____ [2.40]
    DRAM Timing Selectable_______ SPD __ [Manual]

    Performance Enhance = [Standard]

    CAS Latency Time________________ 5
    Dram RAS# to CAS# Delay_________ 5
    Dram RAS# Precharge Delay________5
    Precharge Delay (tRAS)__________ 15

    These are ranges, use the higher first then move lower one at a time while testing between each move with Memtest86+

    ACT to ACT Delay (tRRD)_________ 3-4
    Rank Write to READ Delay________ 9-11
    Write to Precharge Delay_________ 11-14
    Refresh to ACT Delay______________ 48-50 (52-62)
    Read to Precharge Delay__________ 3-6
    Static tRead Value_______________ 7-10
    Static tRead Phase Adjust________ 1-31 << Do not adjust, leave at Auto or Zero or 1-31

    System Voltage Control____ [Manual]

    CPU/PCIEX Clock Driving Control [800mV]
    CPU Clock Skew Control [150ps]
    GMCH Clock Skew Control [250ps]

    DDR2 OverVoltage Control__ [+0.300V] = 2.1v You may have good/better luck with using 2.0V actually with these sticks

    FSB OverVoltage Control___ [+0.1V]
    (G)MCH OverVoltage Control [+0.1V - +0.15V]
