    Default GA-X58A-UD3R rev. 1 - Errors running Prime95 or LinX tests

    I am building a new PC:
    Motherboard: GA-X58A-UD3R (rev. 1.0)
    BIOS-Version: F5
    Graphic: Zotac GeForce GTX 470 1280MB DDR5
    CPU: Intel Core i7 930 @2800MHz (default)
    OS: Win 7 64-bit
    RAM: OCZ3G1333LV4G, 3 sticks of 4GB
    PSU: Corsair HX850W 850W
    SSD: OCZ Vertex 2 60GB

    I am not overclocking, but I did have to manually set the RAM to 1333 and the timings to 9-9-9-20-1T according to the manufacturer.

    The rest of the settings in the bios are default.

    If I have all three RAM sticks in slots 1,3, 5, I can run Memtest86 overnight without errors.

    However, when I boot windows 7 64bit and run Prime95, I get an error almost right away: "FATAL ERROR: Rounding was 0.5, expected less than 0.4" on multiple threads.

    I have tried tweaking the RAM voltages and timings, but I always get this error.

    Or I can only get LinX test to run for 5 to 10 minutes before getting an error.

    If I install one RAM stick at a time in slot 1, I can run either Prime95 or LinX without any problems. I get no errors with any of the 3 sticks installed by themselves in slot-1.

    So, I am pretty sure it's not the RAM or the timings since everything works with one stick.

    Do I have a defective motherboard? Can you think of any other reason why I would be getting errors?

    Thanks in advance for your help.

    P.S. Sorry about the cross post on the Gigabyte Forum, but I wasn't sure if this forum has more readers.

    its probably due to voltages being left on auto, 3 main voltages to set manually are dram,cpu and qpi/vtt......if your at stock clocks then set dram to either 1.5v or 1.66 in bios according to ram,set cpu voltage to normal setting if unstable then set to 1.25v,set qpi/vtt voltage to 1.30000v then test with prime95

    Thanks for the quick response.

    I forgot to say that i already set the DRAM voltage to 1.66 since the RAM spec says 1.65. Do you think it matters if I set it to 1.66 or 1.64? In any case, I get the same errors.

    My QPI/vtt I tried at default, 1.15V. I also tried at 1.20, 1.28, and 1.300V. Still the same errors.

    The CPU voltage is set to 1.29v.

    With my previous settings, I tried one RAM stick at a time in slot 1, then slot 3 , then slot 5. I got no errors on any test.

    As per your suggestions, I used your settings:
    CPU Core: 1.25V
    QPI/vtt: 1.300V
    RAM: 1.66V

    If I have all three sticks in slot 1,3,5, then I get errors almost immediately after starting the Prime95 test.

    With those settings and only one RAM stick, I get no errors.

    I feel like I have ruled out bad RAM since Memtest86 has no errors with all sticks installed.

    I think I have ruled out a bad RAM socket since I get no errors if I use each socket by itself.

    The main issue is with all three sticks at once.

    I will try two sticks at a time next.


    Any other ideas?

    Thanks,
    -Darin

    its normal to set 1.66 for 1.65,it will only use 1.648v in windows,you might need more qpi/vtt voltage try from 1.3 to 1.38v,ahhhhhh 3 sticks of 4gb? so 12gb of ram? you will need alot more qpi/vtt with 12gb try with 1.4v for qpi/vtt

    Sorry about being a noob...

    I had no idea that QPI/vtt had anything to do with the AMOUNT of RAM I have.

    Yes, 12GB total.

    I tried setting QPI/vtt to 1.40v, unfortunately sames as before, errors right away and a BSOD once in a while.

    Should I keep raising the QPI/vtt until it works?

    Is there an upper limit at which point I would damage something?

    I get scared when I start using values that are "pink" in the bios. Makes me think I am risking burning something up...

    Thanks again for your help,

    -Darin

    your safe to go up to 1.5v,personally i wouldnt go higher than 1.45v but its up to you,are you using the latest bios?

    Thanks for the input.

    I have tried everything with no luck. Using Easy Tune 6, I found that I had fewer errors with QPI/vtt set to 1.34V than if I had it up at 1.40V. Regardless, by fewer errors I was only able to get Prime95 to run for 6 minutes before getting errors.

    There are no settings I can find that will run Prime95 for longer than 6 minutes.

    I tried running with just two sticks of RAM last night and Prime95 ran for about 3.5 hours before getting errors, to even with two sticks I am getting errors.

    I am thinking I should try different RAM even though Memtest 86 gives me no errors.

    I have no idea what else to try.

    Do you get BSOD's or just errors?

    Try using 1.14-1.24 IOH voltage, and yes with 12GB you may need 1.3-1.5+ QPI/Vtt, even though you see less errors at 1.4 that may not mean above that wont help so be sure to try it out.

    Another reason could be this memory just is not fully compatible with this board/BIOS yet, so you may need to try different memory or see if you can get Gigabyte or OCZ to validate this memory for this board

    Thanks for helping.

    I do get BSOD's. If I leave the system idle overnight, in the morning it will be BSOD. The Prime95 test is just a lot quicker to check for errors. I can run programs on the PC, but it can take a while for a BSOD. But eventually it always does crash.

    I tried changing IOH from 1.14 to 1.24 and most values in between. Still the same problem.

    I also tried changing QPI/vtt from 1.15 all the way up to 1.5. Still errors.

    I am assuming that setting the values in Easy Tune 6 is a reliable way of changing voltages for testing? If not, then it's going to take a LOT longer to have to reboot every time I change a setting.

    I am thinking I am just going to have to try different RAM.

    What is the BSOD code when you restart the machine?

    The last 4 digits are what matters, it will be shown on the 2-3 line in the window that comes up after a reboot from BSOD

    BSOD Error codes and what they mean:
    0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
    0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
    0X00000101 << Not enough Vcore Voltage

    Yes you can use easytune to test these voltages, it might just be the memory is not compatible is all.

    If you get new memory I'd suggest only 6GB, unless you absolutely have to have 12GB for work or something
