    Post Another GA-EP45-UD3R and G-Skill 4x2GB 1066 Ram Question.

    I'm new to gigabyte and to ram/bios settings/timings. I've been combing these threads for the past two days, but I'm such a rookie. I'm trying to get my system to boot with 8gbs of ram. It boots fine with 4gbs( 2x2gb sticks), but when I try to use 4 x 2gb sticks I get the blue screen.

    What I have:

    GA-EP45-UD3R
    Q9550
    (2) G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

    Could someone please explain in detail what I need to do to get my system to run these 4 x 2gb sticks?

    Thank you in advance

    I changed Performance Enhance...................: [Turbo] to Performance Enhance...................: [Standard]
    and

    DRAM Voltage ……....1.800V............: Auto to DRAM Voltage ……....1.800V............: 2.1V

    My pc now just reboots continuously, no blue screen though.

    Have you added MCH Voltage, if not try 1.24-1.34. If that does not help, try 1.0-1.05

    You are sure all ram is good, just checking. If you are not sure, please set the above suggestions by me and mattlyall06 and test one stick at a time in slot one with memtest86+ >>>

    Your suggestion cured my problem as well. I had set the DRAM voltage to 2.1 and upped the MCH to 1.24 which didn't help at all. However, lowering it to 1.05 got everything working.

    1.24-1.34 and 1.05 was not successful. I didn't have a 1.0. I tried .95 and vista did load, but restarted after 30 seconds. It reset and instantly rebooted.

    Have you tried running the RAM at DDR2 800? We should see if that works before you try running it at 1066Mhz.

    What would I need to change to do that?


    I tried to boot from cd/dvd memtest86+, but my pc would not boot the iso. It would revert back to booting from HDD.

    I used nero burning rom to burn the image "MEMTEST"

    What I tested:

    2 x 2gb sticks in sockets DDR2_2 and DDR2_4 have worked with my original settings from my first post on this thread.

    I then removed these sticks from DDR2_2 and DDR2_4 and used the other 2 x 2gb sticks in sockets DDR2_1 and DDR2_3. The system would not boot to the OS.

    I then put the second set of 2 x 2gb sticks in sockets DDR2_2 and DDR2_4 and my system booted fine into the OS.

    Does this leave me to believe something is wrong with sockets DDR2_1 and DDR2_3 on my motherboard??
