    You have said new IBT failes with 3.77GHz settings also.
    A simple experiment:
    Try CPU Clock Skew 50ps, if it improve things or make no change try 100ps, if it make no change or worse, set ot back to 0 and try MCH Clock Skew 50ps then 100ps.

    it did the first time i tried it. since i have just bumped up the mch up to 1.30v and that fixed that.. right now it is fine at 3.77ghz with the new IBT. i will go in and try 3.83 again with CPU clock scew should i do both the cpu and mch or just one at a time?

    I am not sure, but since this is to synchrinize them it seems to make sense that only one of them should be changed.

    makes since,

    so here we go.
    yes im happy so you know what that means..lol

    well at first i tried the CPU clock scew at both settings wouldnt even boot up
    so i set it back to 0. then changed the MCH scew to 50ps fired up and passed the old IBT but not the new one. so i went and changed it to 100ps it failed the new one but passed 4 out of 5. so i went back and bumped the mch volts 1 notch to 1.32v and it now passed the new IBT. oh dont let me forget i did put hte mem back to a 1:1 ratio underclocking it again to 902mhz. but im happy with that for the time being. let it run here stable fora few days and i will work on getting it up to 1066 again well it would be like 1080 at this setting now.





    ok i got it here changing some things ive never messed with before. no could you explain why and what i just did? and should i ever go any higher on these settings i just worked with??

    you guys are awesome thanks alot. keep on teaching cause im still learning

    Have no idea, may have to up or lower them, depend on changes that effects them such as vp;tages, frequency, and temps.

    EDIT: I don't understand where else can you change MCH Clock Skew?

    ok update. twice friday the system shut down amd restarted on its own. BSOD. i left it at 3.83ghz but backed down the mem from 2.40B to 2.00B did it again. so this last time it did it i went back to 3.6ghz with mem at 2.00B strap.. havent had the problem so id say i need to tweak something a little more. the only thing i could think of is the clock scew again taking it up to 150ps from 100ps. mch is at 1.32v and mem volts are at 2.12v dont want to take that any higher..... and ideas????

    VTT, CPU/MCH Reference, all that good stuff, vcore is always an option though not the first I'd look into.
    I don't think it's the ram itself which is only at 900 with fairly loose timings.

    where do i find the VTT? i have found the CPU/MCH ref havent tried those yet.
    it doesnt seem to want to run on the 400mhz strap. 2.00D?? i did just take the MCH clock scew up to 150ps and have the mem running with the 2.00B strap. here is what i have now.


    i did loosen the mem up from its stock settings of 5-5-5-15, it is now running at 5-6-6-18

    as for the CPU/MCH Ref. start by takeing it up i notch above default settings? should i do both or just one at a time?

    as above it passed the new IBT but after 1 hr and 6 mins of prime95 1 worker failed.
    so i went in and changed some of the settings. CPU/MCH Ref and put the mem back to 2.00D once again passed IBT and im running PRIME95 now.

    VTT = CPU Termination.

    So I hear that the D strap is good up to the mid 400s.

    The timings were already loose. The 5-5-5-15 timings are for DDR-1066 and you were running only DDR-900.

    I really don't like your IBT results. At 3.8GHz and 1536MB I get 24.8GFlops. Just ran 700MB(to match MB per core) with other programs running ib the background and had got 21.9GFlops, I'd expect your system to do 44GFlops+ at this OC. Could be that you need more vcore.

    Try more VTT first, 1.22-1.26v.
    The Reference are a bit more complicated. First set them to default with VTT set to 1.2v, then increase VTT to the desired value, remember the default value for each of them for the new VTT, and then try to change it below or above the default value.

    The Clock Skew can just help as much when it's needed, too much of it is as bad as not enough.

    Which FFT size failed? Run small FFT first for a couple of hours, only then the blend.
