    Default Gigabyte Overclock ram question

    Hi I have a ep45-ud3l mobo and had 2 Gskill F2-8000CL5-2GBPQ 2of 2 ,in slot 1 and 3. My system is overclocked. I had these ram running at 2.1 volts. I was giver 2 other Gskill ram 2 of 2gig to put in slots 2 and 4, these 2 are F2-6400CL5-2GBPQ.My question is, are these 2 new ones being overclock or are not touched just running to give me extra memory? Thkds

    You're mixing your 1066MHz CL5 memory with 800MHz CL5 memory.
    All four memory modules need to run at the same speed with the same memory timings.
    Post a screen-shot of your current setup by following step #4 in http://forums.tweaktown.com/gigabyte...tml#post295784, post #5. Depending on your current overclock settings, you'll probably need to make some bios changes and perform stress testing using Prime95.

    We can best help you after you create a detailed hardware list in the PC Specs portion of your

    Your memory is running at 755MHz and the memory timings are OK for 4 x 2GB ram.
    MCH Core = 1.10 might not be stable for 8GB.
    You need to do some stress testing to ensure that your system is stable.
    Download and install Prime95 Free Software - GIMPS.
    There are three different Prime95 tests; small FFT, large FFT and Blend.
    You do not need to join GIMPS in order to run Prime95.
    There is a link to a Prime95 tutorial in my forum signature.

    You did not provide a detailed hardware list and I don't know which operating system you're running.
    You need to download the 32-bit or 64-bit Prime95 version that matches your operating system.
    Before you run any Prime95 tests, you need to manually enable "round off checking".
    Each test should run for at least 6 - 10 hours without errors.
    If there are any worker errors, create a screen-shot of the Prime95 window and post the picture.
    If one or both worker threads have any errors, your system is not stable and you should stop the test and report the results.
    With no errors, run Prime95 Blend test next, followed by the Prime95 small FFT test.

    It's important that you post detailed results when any errors occur.
    Failing to perform these extended stress tests can lead to instability that can cause BSOD's, system freezes and data file corruption.
    A system that doesn't crash does not mean that it is stable!
    Any questions?

    Hi Thks for the help. I will do testing as soon as I can.If needed the mch core might need to be changed?
    Is there anything else you see thta would need to be changed?

    With 8GB of ram, MCH Core often needs to be set to 1.24 - 1.28 or slightly higher.
    GSkill memory seems to require lower MCH Core settings than most other brands of memory.
    MCH Core that is too high or too low can cause stability problems or boot loops while posting.
    I suggest booting to Memtest86+ - Advanced Memory Diagnostic Tool and running at least 4 full test loops before booting to windows.
    You can download versions for bootable floppies, usb, or optical disks.

    MemTest86+ errors can be caused by incorrect bios settings or faulty memory modules.
    Even one error indicates that there is a problem.
    Most errors are due to incorrect bios settings.

    THks for reply, so should I still do the prime95 stress test first and post results .I then do the memtest if needed? Thks

    I consider Memtest86+ to be a useful preliminary test.
    Do the Memtest86+ test first, because it might help to prevent possible data file corruption in windows.
    It's a very thorough test that often will detect serious bios setting errors.
    Unlike Prime95, Memtest86+ is not a thorough stress test.
    On your system, the first Memtest86+ test loop will probably take about 25 minutes to complete, and all of the following test loops will take twice as long to complete.
    If you want to save some time, run Memtest86+ for two full test loops and then boot into windows for the Prime95 large FFT test.

    If there are no Memtest86+ errors, start your Prime95 test.
    If there are Memtest86+ errors, increase MCH Core one click higher and retest.
    Be sure to post the test number and loop number of the first error.
    If you get hundreds of errors very quickly, your bios settings are seriously wrong.
