    All your volts look ok. Auto for the ram may be a issue though

    So what now 333 MCH is stable and 400 is not?? Thats odd, oh well 333 is better anyway

    these rams are definitely not like others that i use (reaper, ballistix).

    On the stick its written to work between 2.1v~2.3v. it works with 5-5-5-15 timings in only 2.1v, but wont in 2.2v even not in 2.3v =D if i give 2.2v, i can only get it work with 5-5-6-15 =) , not much different but it keeps exciting me though.

    but this, can't even pass memtest no:2, maybe the values of advanced timing control are too tight for it.. any suggestions?

    Another thing is,at 4.00ghz, i cant get the cpu stable w/ 1.36, 1.40, 1.45, 1.50... the values differ from bios to cpu-z about 0.05v and the v-droop is is around 0.045v.Now i'm trying 1.53v which is actually 1.456v and 1.408v on the go. Maybe an higher value of VTT would help in lowering VID ?

    p.s: i tried 2.66D w/ all advanced timing settings sest to auto, 5-5-5-15 @ 2.1v @ 1066 w/ memtest no:5 for 6 hours. 165 total loops, 16 errors, all errors are big chunks like 3gigz. Is that ok? or are we looking for flawless results?

    Thanks.

    Try this for your 400 Settings (Again though 333 is better)

    Ya that is way to much actual Vcore for 4Ghz, people use 1.4+ actual for 4ghz+, most get 4Ghz at 1.28-1.32 actual.

    What Vtt are you using and MCH, Ref voltages all Auto or not?

    well, it's all about the sticks. it can only pass memtest #2 w/ 5-5-5-15 @1056 , on the good side, i can use them w/ 2.0v.. i think of adjusting them 5-5-6-15 w/ better bandwidth.

    i'll write down tne conclusion later =)

    This is what i got stable for now. No errors for 250+ loops of memtest #5 about 10 hours & prime for 2 h.

    now i'll try for 5-4-4-15 or so..

    And what about the dimm skew controls? In an other topic, it was mentioned that +100ps for channel 1 and +300ps for channel 2.

    Skew is trial and error, try this >>>

    MCH Clock Skew (ps)...................: 50-150ps

    The below settings are if you use slots 1 + 3, if you use 2 + 4 adjust accordingly

    Channel A
    Dimm1 Clock Skew Control...............:200
    Dimm2 Clock Skew Control...............:auto

    Channel B
    Dimm1 Clock Skew Control...............:500
    Dimm2 Clock Skew Control...............:auto
