    Smile intel q9550 and gigabyte p35 dq6

    Hello all! if u got the time to spare just a little help needed: i have gigabyte p35 dq6(bios vers. f9b), intel q9550(e0 stepping), 4x1 gig ocz pc6400(ddr2 800mhz) platinum revision 2(ocz2p800R21G)> http://www.ocztechnology.com/product...2_dual_channel.....
    i have question about loadline calibration(sholud i enable it? its on auto now)
    i oc'ed cpu to 3.6ghz-and vcore is set to 1.2875v, ddr2 to 2.1v, fsb +0.1v, gmch +0.1v, pci e to +0.1v, and my ddr2 is oced to 850 usin 4-4-4-12 turbo mode....yet i can't have stable overclock at 3.8ghz i think ram timings are the problem(if i use mem multip.1:2 its about 872mhz)so i just need the correct timings(i think)or what other bios tweak??? also i enabled c1estate? should i disable it?
    thx in advance, best regards&RESPECT!!!!!! DarkStalker

    The link you provided leads to a not found page, I believe this is your ram.

    Using LLC is realy up to you. It may help decreasing vcore but it is a desputed feature.

    Set Performance enhance standard and timing to 5-5-15/18.
    Try increasing MCH OverVoltage up to +0.25 and FSB OverVoltage up to +0.2.
    More vcore may also be required.

    Which strap memory multiplier are you using and what straps are vailable?

    If you can post a screen capture of MemSet main and spd(click spd) windows it may help.

    Pressing Ctrl+F1 in main BISO screen will reveal 2 more optons in MIT, GTLREF1 & GTLREF2. Tweaking those 2 may be needed at high FSB.

    Please use the template in this post to post full settings that are in question.

    What kind of stress tests do you run?

    The memory is rated 1.9-2.1v and has EVP 2.2v. +.05 is low even for DDR-800, don't be afraid yo give it more.
    Are the timings below tRAS auto or manually set?
    Ignore the Clock Driving/Skew.
    You may want to disable C1E while you looking for a stable OC.
