    Well here, then later you can decide about an overclock.

    Stock suggested settings per your setup, Speedstep is enabled though (C1E and EIST), you can disable if you like so your CPU always runs at full speed

    Hey, I got dual channel working with 800mhz! :)

    Here's what I used to get there:
    Performance Enhance: Standard
    Extreme Memory Profile (X.M.P): Disabled
    (G)MCH Frequency Latch: 333
    System Memory Multiplier(SPD): 2.40B
    CAS Latency Time: 5
    tRCD: 5
    tRP: 5
    tRAS: 15

    >Advanced Timing Control
    tRRD: 4(3-5)
    tWTR: 5(2-5)
    tWR: 6(4-6)
    tRFC: 60(50-60)
    tRTP: 6(4-6)
    Command Rate(CMD): 2T
    >>>>>> Channel A
    Static tRead Value: 8(7-9)
    tRD Phase(0-3) Adjustment: Auto
    Trd2rd(Different Rank): Auto
    >>>>>> Channel B
    Static tRead Value: 8(7-9)
    tRD Phase(0-3) Adjustment: Auto
    Trd2rd(Different Rank): Auto

    DRAM Voltage: 2.1V
    MCH voltage: 1.050V
    What do you think is necessary to get them both working at 1066?

    If you ad to decrease MCH to 1.05v to get them stable at 800 perheps 1.00v or 0.95v will get them stable at 1066.

    Okay, I'll give that a try later today.

    Post back if you need more help, and include the settings used that failed if that is the case.

    Okay, I got them working under Chike's suggestion. I didn't change anything but the MCH to 0.95V and the multiplier to 3.20B.
