    Default GA-EP45-DS3R and Memtest86+ Issue

    Hello,

    I recently built a new system and my current setup can pass 24 hours of Prime95 (small FFT). It also seems to work fine when using my other applications like games, media players, and anti-virus. However, my friend told me to make sure I test out my memory as well with Memtest86+. I tried it out and discovered that I can't pass a single run-through of Memtest86+ while using dual channel memory with either slots 1&3 or 2&4 (usually fails test #5). Has anyone else come across a similar situation?

    Here is my current setup:
    CPU: Intel E8500 oc to 3.8Ghz
    Memory: Corsair 2GB (2X1GB) DDR2 PC2 8500
    Mobo: GA-EP45-DS3R w/ F9 BIOS

    You may want to use 402 or so FSB as 400 is right on the 400/1600 strap line.

    And I would advise you to update the BIOS if you are not using the latest. See here for sure, and DO NOT USE @BIOS >>>
    http://forums.tweaktown.com/f69/bios...h-guide-27576/

    Be SURE you load optimized defaults after you flash, set your ram voltage again and save and apply and then reboot back the the BIOS to set your disk settings again and all other changes you want to make. If you are using RAID and you do not do this you will corrupt your Array if you let windows try to load without setting your disk settings again

    Are you using the latest Memtest86+ 2.01? If not you need to as older versions can cause false errors >>>
    Memtest86+ - Advanced Memory Diagnostic Tool

    I say update the BIOS, because often older or certain versions may always be prone to errors.

    And in the end, you may have a dead stick of ram. You should test each one separately with manually set stock speed, main timings and voltages to be sure if one is dying or not. DOA Ram happens all the time and you should always do this test on day one.


    tRAS..........................................15 << is your ram rated at 555-15 or 555-18? If 555-18 set 18 here

    Below is optimal ranges for your ram at that speed. Set to all highest first, then slowly lower and test as you go.

    Advanced Timing Control
    tRRD...........................................3-5
    tWTR..........................................3-6
    tWR............................................4-6
    tRFC..........................................42-44
    tRTP...........................................2-5
    Command Rate (CMD) ....................:2


    Driving Strength Profiles
    Driving Strength ...........................I couldn't find this 1066-1200 << Maybe because of older BIOS. Please try Control + F1 on the MAIN page of the BIOS and the screen will flash then go into MIT and look again

    Channel A & B
    Static tRead Value.........................:8-10

    What you have looks fine, I just posted you some optimal ranges. So you may have a dying stick in the mix.

    Oh hey, sorry. I see you have a newer BIOS. When you flashed to it did you load and apply optimized defaults as suggested above? If not you must. F10 is the latest though, but F9 should be up to snuff as far as working with your ram and having the above Driving strengths. So you board may just not offer them or you did not load optimized after your last flash. Here is your BIOS page if you do want to update (Fixes S3 Sleep) >>>

    Hey, thanks for looking into this. This was driving me crazy!

    You may want to use 402 or so FSB as 400 is right on the 400/1600 strap line.
    I'm pretty new to overclocking. Should I set this in the CPU Host Frequency or the MCH Frequency Latch?

    Are you using the latest Memtest86+ 2.01?

    Yes

    is your ram rated at 555-15 or 555-18?
    It's 555-15

    You should test each one separately with manually set stock speed, main timings and voltages to be sure if one is dying or not.
    Eariler today, I tried each stick in each memory slot and let memtest run 5 passes each using all 8 tests. Both sticks passed slots 1 and 2. Both sticks failed test 5 in slot 3. Both sticks fail on test 5 in slot 4 on the first 1-2 passes, but then seem ok afterwards. I don't know what that means.

    Driving Strength ...........................I couldn't find this 1066-1200 << Maybe because of older BIOS. Please try Control + F1 on the MAIN page of the BIOS and the screen will flash then go into MIT and look again
    Oh! I didn't know about doing ctrl+F1. I finally found it and set it to 1066

    I see you have a newer BIOS. When you flashed to it did you load and apply optimized defaults as suggested above?
    When I bought the board (1 week ago), it had F9 BIOS installed. Should I redo the optimized defaults? Also, I'm using XP Pro for my OS so should I update to F10 BIOS?

    MCH latch you can leave at 400, I mean to use 402 CPU freq (FSB) or so 398/402, ect so you are not right on 400

    Hmm, you may have a bad slot 3 or 4 then. I would do further testing on that for sure and be thinking about a RMA

    As for driving strength, often the next one up from the speed you are using is best

    Well when you installed your CPU did you load optimized? If not yeah, you should always do this when you change major hardware such as install a CPU and you must when you flash as well.


    F10 may be better for you, maybe not that is all up to you. If you want to use S3 sleep then you will need to for sure

    I tried flashing to F10 BIOS and did the optimize defaults/redo my settings, but I still get errors on slots 3 and 4. I'll probably try rma-ing and see if the replacement works. Thanks for all your help Lsdmeasap!

    Ya, sounds like you may have some bad slots on the board. Good luck with your RMA, I would do it if I was sure the slots were bad
