    the 2x2gb are rev. 2.1 and the 2x1gb are rev. 5.1

    i want 6gb because im using flight simulator X. and this game use until 4gb so 2gb for the O.S. and 4gb for fsx....and also for modelling

    ok...so i sell the 2x1 and i but another 2x2gb with also the same revision

    ps. this motherboard support 8gb ram at 1066 with timing 5-5-5-15?

    Don't eush to sell or buy anything until you exchusted settings options, you might end with the same exact problems even with all sticks being the same model & revision.

    It supports "up to" 16GB of ram, again no one will guarantee you'd be able to use the memory at 1066 or at all.

    for me running with the p35-ds3r with 6gb at 1000 mhz is already a big result. anyway which gigabyte motherboard socket 775 can run 8gb ram at 1066 mhz?

    ill try to make some more test tomorrow morning..its 01.00 oclock here in italy and im go to bed soon.

    If MCH OverVoltage +0.1 does not boot try +0.2, but remember too much is not good as same as too little.
    If all fail, boot with the 4GB kit and DDR OverVoltage +0.3, go to PC Health Status and see what value is reported for DDR Voltage.

    hi...ive tried all the test but nothing....with 6gb is alien for this motherboard....

    how can i understand if MCH OverVoltage is too much or not?
    in my last test:

    - ive modified HPET mode to 64-bit mode
    - ddr2 overvoltage control: +0.3V
    - Mch overvoltage control: +0.2V

    on pc health status (with the setting above):
    Vcore: 1.220V
    DDR18V: 2.032V
    +3.3V: 3.328V
    +12V: 12.048V


    can i damage my pc with MCH overvoltage at +0.2 or +0.3?

    Wgen I said too much I meant that there is no need to use +0.2 if +0.1 is enough.
    MCH value cannot be monitored, +0.2 should be safe, and you don't need to use +0.3.

    All that you have tried was with memory at 800MHz and default timings?
