    Set SMM to 2.66D and see then. Possibly you will be able to lower tRD(Static tRead) to 7.

    Here's what happened: I changed the SMM to 2.66D, now the ram is running ~1045Mhz, AND in the BIOS menu (both channels):
    - BEFORE setting SMM: Static tRead Value -----------------default 8---- : [8]
    - AFTER setting to 2.66D: Static tRead Value -----------------default 10---- : [8]

    So I changed it to 7, but the linx failed after the 2nd test, then with that value on 6 the machine became unstable and the hdd began to stop and spin up again, and then restarted right after boot up into the windows.

    As I set the tRead value to 10 the linx did run fine, but it failed to pass the 3rd run. Although GFlops are still around ~45.xxxx, I guess these settings are not OK.

    Maybe the memory needs a bit more voltage, what is max voltage according to the sticker on it? Kingston site says 2.2-2.3 but don't set above 2.2 if max printed on the sticker is 2.2.
    Try one click up MCH Reference (0.84 @ 1.2v VTT, about 0.868 @ 1.24v VTT).
    If this not better set MCH Reference as before and try one click below max for CPU Reference.

    Nothing is written about the voltage on the sticker, I already checked. Everything I have found about my memory sticks (timings and voltages) are from the kingston webpage.

    OK, I will try to set the MCH ref one click up!

    And what about the tReads value ? After changing the SMM to 2.66D the default for that is 10. Should I stay on 10 with that for the first tests ?

    If tRD 7 and 10 both fail the same leave it 8 untill it's stable then try 7, no point to try 6.

    The tRD depends on FSB DDR and CAS value, higher RAM:FSB ratio, and/or lower CAS enable lower tRD.
    For example , on my P43 board, at 266MHz FSB DDR-800 CAS 4 tRD 2 booted, DDR-1066 CAS 3 booted, at 333MHz FSB they had to be 4 and 5 respectively (didn't test stability at any of those settings).

    You just increased RAM:FSB ratio, so 8 or lower should be OK.

    If the SMM is set to 2.66D (ram@1045mhz) the linx fails, no matter what....

    Did you try increasing DRAM Voltage, and change the references?
    You can also try to increase MCH Core one step up, and VTT 1-2 steps up.

    Umm, I increased the ram voltage up to 2.28 and set the tReads to 10 (default), this is what happens:



    Doest this matter too much (in complete system speed)? I mean to set the ram speed up to 1045mhz (smm 2.66d) ?
    Coz if it doesn't, then I would maybe rather stay with Auto setting (941mhz) and leave the ram-voltage@2.2, maybe it is safer/healthier to the rams too, isn't it ?!

    Up to you of course, ram don't make that much of a difference anyway.
