    Try what profJim suggested, the 2.00B multiplier.
    See if forcing 800K FFT speeds the failure.
    Select custom, and set min and max FFT to 800.

    I have set the 2.00B multiplier, and set min and max FFT to 800.

    Ah, good no need to wait too long.
    <s>Have you tried the 2,00B multiplier?</s>
    LOL I must stop doing it.
    Try a higher VTT.

    Should I set back the 2.00D multiplier, because for B-multiplier the RAm fsb is 333? Higher VTT then try all the combinations with MCH reference?

    No, it's the bus frequency that makes the difference.
    Try with VTT 1.22, then a bit more vcore just to make sure it's not it.

    Setting the VTT to 1.22 caused boot failure, so I raised Vcore and just passed prime95 custom test with FFT 800K without errors or warnings. Is it normal for screen to flicker during boot? My current Bios settings are:

    Try the same the 1.2VTT. The references are tide to VTT so they may need to be changed at different VTT values.
    Flicker how?

    I will try mch reference from 1-4 below default and 1-4 above default, then the same with cpu reference. The only difference will be higher vcore? I restart , bios read ok, but when it starts showing the windows logo the screen flickers twice-once upon showing the logo, and second time just before log on. I will try to film it then upload.

    Try just more vcore with the same settings u had before (as you posted).
    Then try the same reference procedure with 1.22v VTT and so on. Just remember to make the changes at 1.2v VTT.
    also list the values of references for 1.2v VTT (eg. 0.72 @ 1.2 VTT), it's more clear and easy to understand.
    For better understand of what they actually do you can read Understanding GTL Reference Voltage.

    I have run a lot of combinations concerning MCH and CPU references but didnīt come up with a stable system. Can I try combinations of MCH and CPU references with a little bit higher Vcore? Here are the tabs of what Iīve been doing:

    Vcore / VTT / PLL / CPU REF. / MCH CORE / MCH REF. / Prime95 Blend Test


    -1 [1.39375V] / [1.200V] / [1.570V] / [0.760V] / [1.200V] / [0.740V] / 1h.4min. fails on 960K

    The -2 tab had the best result, so I left all the values only worked with CPU Reference:
    Vcore / VTT / PLL / CPU REF. / MCH CORE / MCH REF. / Prime95 Blend Test

    That wasnīt succesfull so I repeated the tests with VTT 1.22
