    Default EX58 UD5 Memtest86+ errors - where to go next?

    Hey all, first time poster here that just put together an i7 build three days ago and am in the midst of stability testing at stock settings before tackling some overclocking.

    I have run into a bit of a problem when testing RAM (always seems to be RAM for me) and was wondering if I could get some opinions on where to go next. Motherboard is Gigabyte EX58 UD5 using F9M bios with a i7 920 c0 at stock speeds and 6GB of Corsair Dominator 1600mhz DD3 RAM (TR3X6G1600C8D).

    My initial testing was done using Prime95's blend test with all settings at stock, my memory was running at 1066mhz and I was able to get through a night of testing (9 or so hours) without any problems. I went into the bios and enable XMP which bumped my RAM up to 1600mhz and booted up a copy of Memtest86+ 4.00. Leaving this running over night I woke to find a slew of errors. I dropped the RAM back down to 1066mhz and ran one of the tests that caused a lot of errors (#7) which caused the same set of errors to crop up.

    At 1066mhz at the desktop or playing games (Fallout 3, Torchlight, World of Warcraft, Left 4 Dead 2) I experienced no stability problems. At 1600mhz I played some World of Warcraft last night and experienced no stability issues. The time played was on the scale of only a couple hours so I would be hesitant to say that my system feels stable. So now I am wondering if I should bother playing around with voltages and manual timings or going ahead and testing one stick at a time to see if I can isolate the problematic memory.

    disable xmp as its not as reliable as setting the ram yourself,all you have to do is select quick timings and enter your rams spec timings,then select mem multiplier and up it to 1600mhz,then set dram voltage to your rams spec usually 1.64-1.66 in the bios,also i would manually set cpu voltage to normal setting as auto will always overvolt and set qpi voltage to 1.30000....then test with memtest

    Went into the bios and set timings as 8-8-8-24 2T. Set DRAM voltage at 1.64 and CPU voltage at Normal, QPI voltage at 1.31.

    Fired up test #7 in memtest86+ and I had errors within 8 minutes.

    Bumped up the DRAM voltage to 1.65 and the test made it to 18 minutes and failed. Should I bother with bumping up the QPI or touch anything else or would it be a better idea to start testing each stick by itself?

    with a c0 chip you might need more qpi try with 1.350000 your safe to go upto 1.50000 no higher tho,you might need anything from 1.30000-1.400000 just keep testing and raise a few clicks and test untill theres no errors,also you should be able to set ram command rate to 1t not 2t

    What address you get the errors? Is it always the same?
    Try each stick individually, maybe one of them is faulty.

    Always the same address (2 of them) and the same Error Bit if that makes any difference. I plan to test individual sticks if I get the error after bumping my QPI voltage all the way up to 1.4 in increments.

    try with memtest 4 aswell as it might be software related,just to see if you get the same errors with memtest4

    With DRAM voltage at 1.66 and QPI voltage at ~ 1.33 I just completed one pass of test #7 that was generating errors before. I am crossing my fingers and hope that this QPI voltage will do it for me but want to let it run through a couple more passes before I feel good about it.

    I should be ok with 1.66V DRAM correct? I thought I read that Intel recommends not going over 1.65V.

    yes if you look in easytune it only uses 1.64 but im set at 1.66 in the bios so its safe to use,there isnt an option for 1.65 in bios anyway,and yeah being a c0 chip youll need slightly more qpi than a d0 no big deal...hope it works for you

    With my QPI at 1.335V and my DRAM at 1.64V I was able to complete 5 passes of the memtest86+ test that was generating errors fine. I boot into Windows and now I get random restarts. Any ideas as to what could be causing this? I looked at my temperatures and I was idling at 34C - 35C so it doesn't seem to be heat causing it.
