    OK, so what did you set it to when Vtt is at 1.2?

    B multi's are For FSB 333-400, and D multi's are for 400+ FSB. These are internal NB timings and speeds, set MCH Strap to Auto and then you can choose memory multipliers from either strap

    i dont think my vtt has ever been 1.2, or do you mean when i was setting it? i put like .880 cause .863 wasnt wasnt available, but once i put it to 1.3 .863(i think it is) was available so i picked that(after researching of course). vtt is 1.3 now...

    About the mch, either way its going to be 2.00B or 2.00D.. nothing is different other than the letter? (at 2.00.. 2.40D is obviously different)

    Ahh so you are setting MCH Ref wrong then possibly, but yes I meant when setting MCH Ref. To set MCH Ref you need to put Vtt to 1.2, then adjust MCH Ref, then raise Vtt back to what you want to use.

    See the MCH GTL link in my signature for more on how you are supposed to adjust this value.

    A lot is different between 2.00B and 2.00D, those are internal NB timings and speeds. Above 400 FSB using D will be better
