    Default GA-EP45-DS3L stable with 2GB, not post with 4GB?

    Hi all, new to this forum with my new build. Currently have this new gigabyte board, but having trouble with my ram memory settings. Current set-up: GA-EP45-DS3L w/ bios v.9, Q9550 quad, 2 gb corair dominator (2 x 1GB), HD 4870, and velociraptor 300 GB. I'm stable running 2 GB sticks in dual mode, however, when inserted 4 GB, would not even post. Left in 2 sticks in 1 and 3 slot, stable, then change up with other two stick at 3 and 4, stable. So I dont think it my ram stick since all four works when running two sticks. CPU temp idle at 41 C and VGA temp idle at 79 C. I bought 4 sticks so planning to use all 4 sticks.

    Memory brand:
    Corsair dominator XMS2-8500
    model: CM2X1024-8500C5D
    1024MB
    1066MHz
    5-5-5-15
    2.10V ver5.1

    Stabe at 2 GB with the following settings:

    When insert all 4 sticks, it would not even post. However, when drops the Ram speed down to 800Mhz, it would post and runs, but not stable. What other settings could I do to make it stable with 4 GB, instead of two. I would like all 4 sticks to be at 1066 MHz if possible. Thanks.

    Thats hot idle temp for your GFX Card, just thinking out loud there. It has no effect on your stability

    For 4GB stable with your above settings, here is what you should change >>>

    Thanks for the response. I will try setting and post back. I'm waiting for my aftermarket cooler to come in. Ordered a thermalright T-rad, hopefully that would lowered my temp.

    Tried setting with 4 sticks, system just continually restart itself and wouldnt even POST. However, still post and run with 2 sticks of ram.

    What exact settings did you set for 4 sticks? And this is 4x1 of matching pairs correct? Just have to ask to be sure

    I used the setting that you have suggested in previous post. This is 4 sticks (4 x 1 GB). Ran memtest86 last night with ur setting for 2 sticks, no errors. Still will not post with 4 sticks at 1066mhz.

    Please post the table back, with the exact settings you use to try to get 4 sticks to post and I will advise

    And please test this ram, one by one in slot one. I know you said you thought you ruled this out in post one, but simply booting with each set is not a definitive answer as to whether each stick is 100% working order >>>
    Memtest86+ - Advanced Memory Diagnostic Tool

    Must be that version of Memtest86+. Please test each stick in slot one, at stock speed and timings, and manually set voltage to be sure you do not have a DOA Stick in there

    This the exact settings as suggested by you to try booting up with 4 GB at 1066mhz. Will not post with this settings.

    Jus finished testing each sticks in slot one with memtest86+. all sticks passed with no errors. I am able to post with all four sticks when lowered the memory speed to 800mhz. It now running stable, but not at the advertised speed of 1066mhz with the above settings.
