    Default EP45-UD3R & G.Skill SDRAM

    I was having random BSOD with Windows 7 and a new Gigabyte EP45-ud3r motherboard.

    I've recently purchased the EP45-UD3R(1.1) with G.Skill F2-8500CL5D-4GBPK SDRAMS 2pcs for a total of 4GB, and a E6300(R) 2.8 ghz Pentium.

    CPUZ was reporting that I was running at 1.8v DRAM Voltage. The ram sticks clearly says 2.0v-2.1v. So I changed the BIOS DRAM voltage from AUTO (1.8v) to 2.1v. Now I no longer get the BSOD several times per hour. But I get a few randoms program crashes even after reloading Windows 7.

    Is this the right memory for the EP45-UD3R motherboard ?

    Any thoughts?

    BTW: Using BIOS F11

    Attached a CPU-Z report

    If you have not began with optimized defaults, please do so and reaplly DRAM Voltage.
    For stock settings:
    Set Performance Enhance to standard.
    Set MCH Core 1.2, increase up to 1.24v if needed. If more MCH Core does not help try 1.05v down to 0.95v.
    A screen capture of MemSet main(click >>) and SPD(click spd) windows would be helpful.
    After everything is stable some tweaks can be applied for optimal memory performance.

    Don't leave things for random crashes. Run 6+ passes of memtest86+ first, then 8+ hours of Prime95/Orthos blend torture.
    Watch core temps with RealTemp or CoreTemp, they should be below 60c iof there is not problem with CPU/case cooling.
    You can find the programs mentioned above in http://forums.tweaktown.com/f69/late...30/#post284762

    Ok I've made the BIOS changes that you suggested. Ran memtest+ for many passes with no errors. Now I'm reloading Win 7 since it's been unstable. Next I'll run prime95 and see how it goes. Thanks for your help.
