    Default Ep35c-ds3r mobo with 4x2gb ocz reaper 8500 @1066

    Hi to everyone....!
    I have a system with:
    gigabyte ep35c-ds3r mobo rev 2.1 bios ver f3
    ocz memory hpc reaper 8500 4x2gb @1066mhz timings 5-5-5-18 @2.2 volts and core 2 duo 8300 @ 2.83 (not overclocked).I have read lots of posts but I didn't find any solution. I would like you to inform me about the settings i could use at bios because with the default settings and memtest86 ver. 2.11 after 3 passes I get some errors... thanks a lot!

    Can you please give me a link to your memory so I can be sure of a few things.

    And then give me the settings you are using and I will advise back >>>

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

    First of all thanks again for your help...
    Now I'll give you all the information you need! I have two sets of this memory: OCZ Technology | Products | End of Life | OCZ DDR2 PC2-8500 Reaper HPC 4GB Edition . Each set has 2 modules of 2gb ddr2 @1066 2.2v timings 5-5-5-18. So I have 4 modules of this memory. Yesterday I tested each pair separetely to find out whether I had any bad module or not. So I cleared the cmos by removing the battery and putting a jumper on my mobo. Then I run memtest 2.11 with the default settings for hours with 0 errors. So I thought that each module is OK. The deafault settings I use:

    <o:p></o:p>
    <o:p></o:p>
    With these settings, each pair of memories can run memtest for hours and 0 erorrs. Now I would like you to inform me what settings to use to run memtest with 4 modules. thanks again!

    After 6 and a half hours of testing with memtest 86+ v 2.11 here are the results:
    pass 1-->0 errors
    pass 2-->0 errors
    pass 3-->2 errors at test #5

    I also tried the same setings but:
    Ddr2 over voltage control +0.4
    (G)MCH overvoltage control +0.3

    and I run only test #5. I get errors.... thanks again for your time... what else should I try;

    3.20 is 3.20B sorry, some boards have letters/symbols for the straps and some do not

    Try tRRD of 4 with all the same except use +0.3 Ram, and +0.3-0.35 MCH

    Test 5 is the one that will fail if something is wrong, since you pass the others then you are almost there. How hot is your NB during testing? Can you touch it for more then 10 seconds? If not heat may be a issue and you may need to add a 40MM fan on there

    I put this cooler on my northbridge chipset:
    Thermaltake Global > Product > Cooler > Chipset/Memory/VGA > ChipsetCooler > ExtremeSpiritII > CL-C0034
    I also tried the settings you just sent me... I get errors again. Thanks for helping me.
    Is there anything information I can give you to help you heping me?

    Hmm..

    Ya that is a nice cooler, I have used it several times!

    Let me see your full settings you are using now, and before you give them to me can you please run orthos Small and large FFt, but not blend. Run them for about a hour and see if all is well, if not you may have some issues other then ram itself.

    Just trying to see if it is RAM only, or a combination of ram and something else.
