    Default Memory Stability Issues EP43-UD3L

    Hello all.

    So early last week I decided to upgrade my computer to play ARMA II, which is ridiculously demanding for no particular reason.

    My new system components are listed in my signature.

    As soon as I got the board I had issues.

    My first setup included the stock BIOS settings and my memory setup in dual channel mode in slots 1 and 3. I was able to get the Windows 7 RC installed, but had a BSOD near the end of the installation and configuration process. Windows was completely unstable. I was also getting boot loops where eventually the computer would start or I would pull the power cable for a bit and then it would start.

    I got online and started looking for answers and found this place. So I did the following:

    - Loaded optimized defaults
    - Then setup the BIOS as follows per some recommendations around here:

    Code:
    Motherboard: Model:  Rev#:  Bios Version:
    Cpu: E8400 VID 1.3V
    Ram: OCZ Technologies, OCZ2G8004GK, OCZ Technology | Products | Memory | OCZ DDR2 PC2-6400 Vista Performance Gold 4GB Dual Channel
    Power Supply Unit: Offbrand, ??, 600W voltages appear stable

    </pre>
    With the above settings, I was able to sucessfully install Windows 7.

    Once installed, I ran Orthos, but it eventually fails running a blended test. CPU temps are fine at about 50 *C under full load with the case closed.

    So I moved to running memtest86+.

    With the RAM in slots 1 and 3 I get about 105 errors in the upper address ranges (4000 MB - 4800 MB) in Test #4. I reversed the sticks and got similar errors in a similar range.

    I uppded the MCH voltage to 1.3V and ran the same test again with similar results.

    I down clocked the RAM to 6-6-6-18 and put the MCH at 1.2V and ran the same test with similar results.

    I put the RAM slots 1 and 2 at stock timings and MCH of 1.2V and ran the test and received fewer errors, but still some across the address range.

    With only one stick in slot 1 I don't get any errors.

    I have ran this RAM in another mobo/CPU combination with the same harddrive and power supply and it functioned within Windows 7 without issue.

    I'm nearing my wits end with this motherboard. I've never had to adjust BIOS settings JUST to get my equipment to boot and operate properly before. I've had to modify the BIOS to push the system beyond its defined limits, but not to just have it work. Very dissapointed in my first forey into the Gigabyte world so far.

    Both sticks individually give no errors?
    I wouldn't lower vcore below default.
    As default BIOS usually sets DRAM Voltage to 1.9v so you may want to try that. IMO XMP should be left auto or set to profile1/2.
    If I am not misteken I've read in one of Lsdmeasap latest posts that 4890 may need aome ICH increase, try to search that.
    The latest F5 BIOS suppose to have more memory compatibility, you may want to flush it.

    I only tested one stick individually, but I'm pretty convinced that it's the board not the memory. It always errors in the high address ranges regardless of which stick is in the second channel.

    I've increased the Static tRead value to 10 and the Vcore to 1.3V, with the exact same results. I'm going to try some other RAM I have, but it's only 2 x 1GB.

    The F5 bios doesn't list memory compatibility as a change feature on Gigabyte's website.

    I'm seriously doubting the 2 x 2 GB is going to work with this board.

    Maybe we see different sites?
    F5 2009/08/13 1. Improve memory compatibilities.
    Also test 1 stick in slot 3 alone, if the problem is with the board it may show errors there.
    Dual channel should also work wit slots 2 & 4, another thing you may test.

    You're definitely correct about the F5 BIOS, sorry about that I'm not sure what I read. I'm going to go ahead and install it now.

    No dice with the new BIOS either.

    I went ahead and returned my memory locally and I picked up a different brand. Going to see if it makes a difference.

    2x2GB should be ok if you can set MCH Voltage in your BIOS.

    Once you update post your full settings you are trying that fail and we can advise back

    Well, I can now pass the Memtest86+ tests I was failing before with the new Corsair XMS2 memory.

    I still feel the other memory was functional. I just think it wasn't playing nice with this board. I didn't finish the Memtest just yet as I wanted to jump on some Orthos first. That and I'd actually like to USE my computer.

    I'll be back if I have anymore issues.

    Thanks to everyone who contributed.

    It could have just been settings, so if you want me to have a look with your old memory to be sure before you sell or RMA it let me know and we can look into it.

    Of course once you have time to play and USE your system, I know how that can be!

    I outlined the settings I started with and what I worked through in my first post.

    I had followed your memory guide about setting the MCH voltage (tried 1.2 - 1.3 with 1.2 being required to boot with both sticks), the Static tRead and the tRFC. No dice on any of it. I even tried relaxing the memory timings at the standard clock speed with nothing.

    I had completed a fairly rigorous set of testing and always errored in a similar fashion regardless of the memory stick locations. I was to the point where I don't think a couple of nanoseconds or a tenth of a volt here and there were going to fix it.

    Thanks for the offer though. I'll be back for overclocking once I verify that I'm stable at the standard clock speed.
