    Default Stable 6GB at 1866MHz with GA-EX58-UD5

    Hi there to all.

    I am having trouble getting the 6GB triple channel 1866MHz OCZ memory (OCZ3P1866C9LV6GK) running stable at rated timings (or even at 1600MHz) on a GA-EX58-UD5 motherboard.

    I've done some steps so far. I won't bore you with details but after a lot of reading I managed to log into windows trouble free while at 1866MHz. Unfortunately though, the minute I run Everest system stability test, the computer either froze or did a restart without a BSOD and without an event log error either.

    I decided to lower the mem frequency to 1600MHz and that seemed to do the trick with the system stability test, but although the lockups did not appear so often, they did not disappear completely either. I still had a lockup or two a day, usually when doing something CPU demanding.

    Now I am at 1200MHz and so far (almost two days) I didn't have a lockup or restart, but I can't say that I am very happy running at 1200 instead of 1866.

    I always had mem voltage at 1.66V and qpi/vtt at 1.35, as it is suggested in the OCZ forum. I even tried a little bit higher too while at 1866, but in vain. Of course the main timings where set manually at 9-9-9-28 and I also had tRFC at 88 and command rate set at 2 (also suggested by OCZ). Turbo mode off and Performance Enhance Standard.

    My system specs are on my signature. I am running at 3.2GHz at the moment, but please have in mind that the exact same things happened at stock CPU speed too. I think I may have also tried it with the CPU underclocked.

    Memtest pass ok both at 1866 and 1600.

    So any suggestions? Any advanced memory manual settings that could help with the stability? Maybe some voltage increase somewhere that doesn't work very well at auto?

    Thank you in advance.

    Can you please give me your settings in full you are trying for 1866, template is in my signature. There shouldn't be any need to run your memory at 2T either.

    Please do add a link to your ram if you dont mind. I guess I can look it up though since you added it in your signature. I assume it can run 1T no problems. You just need to find the right voltages and uncore/QPI Settings likely.

    Thank you for the quick response.

    My ram is this one. The 6GB kit.

    Now for my settings. This is what I have now, running stable at 1200ΜΗz and not so stable (2-3 totally random lockups or restarts per day) at 1600Mhz.

    If I leave the BCLK at 133 and set the CPU Multi at x20 (2.66GHz), the Mem multi at x14 (1862MHz), the Uncore Multi at x28 and the QPI Multi at x48, the computer boots but it freezes at the windows logon screen, probably because the Uncore frequency is bigger that the QPI one.

    Where do you optimally want to run your CPU at before I advise back? I mean in regards to temp and total freq.

    I wouldn't mind to run at 3.2GHz if possible. Now with 1.2V CPU Vcore, I am at 44 C idle and around 64 C at load, with stock cooler, which I believe is fine.

    Ya that sounds fine, I just wondered since you had not mentioned what you wanted or what cooler you are using.

    Try this for 3.2 with ram at 1700 then >>

    To try 1600Mhz with the below settings, change CPU multi back to x16, uncore to x18, and ram multi to x8

    Thank you very much!!!

    Will try, stress, test for a day or two (unless there's a lockup earlier) and report back.

    The only setting that worries me a bit is the QPI/VTT over 1.35V, because I've read that it may "hurt" to have such voltage for long periods (I think intel specs, max this one at 1.35 too). But will certainly try and see how the stability and temps go.

    K, good luck with things. I know 1866 and above can be tricky if you are not fully used to x58 yet, so if you continue to have issues see if you can get 1600 stable and then we can work on more.

    QPI/Vtt voltage is fine high, many packages require this at stock settings and are programmed as such in the XMP settings. See more of my thoughts here about high QPI/Vtt voltage it has links to a few sites showing how this is normal for high speed kits >>
