    Default Re: Gigabyte EP45-UD3P - memory issues

    So after 3 months of normal operations, the BSODs started suddenly again. Fired up Memtest86+ and lo and behold, RAM errors...

    Increased the MCH voltage to 1.26v, then to 1.28v and was still getting RAM errors in Memtest, so stopped. Then I did the following:
    1) Pull out a set of RAM (2x2GB)
    2) Reset MCH voltage back to 1.10v
    3) Ran memtest on the remaining set on the first set of RAM slots

    12 passes of test 5 and 5 passes of the full memtest tests were successful. Now moved the same set to the 2nd set of RAM slots. 21 passes of test 5 were successful, so reset memtest to start from the beginning to do all of the tests.

    And then when the tests were running, I noticed something strange with the RAM type and settings being displayed by Memtest86+. They were:
    Type: DDR3
    Speed: 333 MHz (DDR666)
    Timings: 57-15-15-63
    Channel: Dual

    So is this a known issue with Memtest86+ sometimes misreading RAM timings or do I have a problem with this set of RAM slots which could be the cause of the RAM issues I've experienced the past few months?

    A reboot later and the RAM type and settings were back to normal in Memtest86+.

    Thanks.

    I don't recall seeing strange Memtest86+ readings like you reported. Are you using the latest 4.20 version?
    So after 3 months of normal operations, the BSODs started suddenly again.
    Not including specific information is like calling up a doctor and saying "I've got a bad headache, what's wrong".
    You should configure windows so that it doesn't automatically reboot when a BSOD occurs. It's best if you include the BSOD error code which will be a hexadecimal number like 0x0000001E and the specific error message. See the attached picture.
    It might help if you tell us what you were doing with your system when each BSOD occurred and if there is a pattern to when each of the errors happened.

    Post your current settings using the bios template at the end of http://forums.tweaktown.com/gigabyte...tml#post295784, post #5.
    It will also help if you include the screen-shot described in step #4 in the linked-to post.

    FWIW, about every 3 - 4 months, I give my system a thorough interior cleaning and re-seat all plug-in hardware and cable/wire connections.
    I always first power off my power supply and disconnect the psu from the wall socket or the back of the psu.

    Thank you for your help profJim, much appreciated.

    Yes, that's the version I'm using.

    Sorry, I know but didn't have that info on hand as I didn't want to start Windows again until the mem errors had been sorted.

    You should configure windows so that it doesn't automatically reboot when a BSOD occurs.
    Have done so now.

    if there is a pattern to when each of the errors happened.
    FWIW, for the small amount of time I could see the error before the auto-reboot, it was a different stop error. Last time I opened up the minidump with windbg, a different driver was the issue each time. Symbols were properly loaded.

    Went through your instructions in the linked thread but still couldn't get 8GB stable even at 1.28v MCH, so switched back to 4GB and no issues after 8 runs of Memtest86+. Am now back in Windows with that amount of RAM.

    I'll capture the BIOS settings and post them.

    Beginning to think the board is the issue though as one of the USB ports is no longer working properly - it wouldn't report my keyboard to Windows properly. Swapping to another USB port solved the issue.

    With 8GB of memory:
    • Performance Enhance = Turbo might be part of the problem
    • XMP = Disabled and manually setting memory timings is usually a better approach
    • 1066MHz might not be stable, somewhat lower memory speeds might be needed
    We need to see your current bios settings and screen-shot (step #4) to make specific recommendations.

    Default Re: Gigabyte EP45-UD3P - memory issues

    From post #41, your motherboard memory slots are fine when you tested one set (2x2GB) in slots 1 & 3 and also using slots 2 & 4.
    You should test your remaining memory in slots 1 & 3 to verify that there aren't any Memtest86+ errors.
    With no errors, try the following settings for 8GB of memory:
    Code:
    Performance Enhance ------------ : [Standard] <-- set to STANDARD when overclocking
    Extreme Memory Profile - (XMP) - : [Disabled] <-- Leave this Disabled
    (G)MCH Frequency Latch --------- : [Auto]
    System Memory Multiplier ------- : [2.40B]
    Memory Frequency (Mhz) ---1066-- : 800 MHz
    
    Static tRead Value ------------- : [7] <-- same setting for memory channels A & B
    
    MCH Core ------------- 1.100V -- : [1.22] <-- 1.24 - 1.26 might be needed, try 1.16 if there are Memtest86+ errors
    
    Limit CPUID Max. to 3 ---------- : [Disabled]
    No-Execute Memory Protect ------ : [Enabled]
    CPU Enhanced Halt (C1E) -------- : [Disabled] **
    C2/C2E State Support ----------- : [Disabled] **
    x C4/C4E State Support --------- : [Disabled] **
    CPU Thermal Monitor 2 (TM2) ---- : [Enabled]
    CPU EIST Function  ------------- : [Disabled] **
    Virtualization Technology ------ : [Disabled] **
    Integrated Peripherals
    Legacy USB Storage Detect  ----- : [Disabled] **
    
    ** temporarily disabled for now
    If the Memtest86+ tests complete without any errors, boot into windows and run IBT (Intel Burn Test) or LinX for 5 loops using 2048 MB of memory. If this test completes without errors, run Prime95 Blend test for 3 hours. If you're not familiar with Prime95, click on the Prime95 tutorial link in my signature.

    I have since tested both sets (set one in 1 & 3, 2 & 4 and set two in 1 & 3, 2 & 4) without any errors in Memtest86+ when only each set is in there (so 4GB). If I put all of the sets together (8GB), Memtest86+ errors about 6 runs into test 5.

    Will implement your settings and post back the results.

    Hi profJim,

    Implemented your settings and Memtest86+ failed within a minute into test 5. After I took the picture, the error count was up to 117.

    Lower DRAM Voltage to 2.00 - 2.04 and see if the results are better or worse.
    If you are using MCH Core = 1.22, increase it in steps up to 1.30 and note if the results are better or worse.
    If there are no improvements, try MCH Core settings between 1.05 and 1.20.
    See if there is any pattern in the #5 test results.

    Hi profJim,

    Here are the test results:
    MCH Core = 1.22V
    DRAM Voltage 2.00V = 4m 36s
    DRAM Voltage 2.02V = 52s
    DRAM Voltage 2.04V = 50s

    DRAM voltage = 2.100V
    MCH Core 1.22 = 54s
    MCH Core 1.24 = 49s
    MCH Core 1.26 = 50s
    MCH Core 1.28 = 50s
    MCH Core 1.30 = 49s

    MCH Core 1.05 = 49s
    MCH Core 1.10 = 54s
    MCH Core 1.16 = 49s
    MCH Core 1.18 = 50s
    MCH Core 1.20 = 49s

    So since MCH Core 1.22V and DRAM 2.00V provided the best results, I tested DRAM 1.98V with MCH Core 1.22V and it's 11:10 into Test 5 runs and no errors yet.

    I find this a bit strange as the RAM is rated at 2.1V, as per the stickers on them. Is it an MB unable to supply that much power to the RAM slots issue?
