    Default GA-EP45-DS3L causing system lock-ups

    I'm putting together a new system and am getting random system lock-ups, sometimes in BIOS, but usually 30 seconds or so after booting Windows XP. My system specs are listed below:

    GA-EP45-DS3L with newest BIOS
    Intel Core 2 Duo E8400 3.0GHz
    Corsair XMS2 2x2GB DDR2 800 (PC2 6400)
    HIS Radeon 4870 512MB
    Coolmaster 650W power supply
    Windows XP SP3

    I managed to get Windows XP installed (after 1 or 2 tries) and have since been treated to my system freezing up shortly after booting. Memtest86 will lock up on step 3 every time with one or both memory sticks in any slot combination. BIOS will lock up if I play with any of the memory settings. I've been wrestling with this for a week and I'm really at wits end. If I can't get this fixed up in another dy or so, I'm probably going to suck it up and buy another motherboard.

    EDIT: I fixed the problem. Dropping MCH core voltage to 1.05V allowed a single RAM stick to pass Memtest and further reducing to 0.95V has allowed me to run the system with dual channel RAM reliably.

    Maybe faulty ram modules. Can you borrow one or two to try? Or even just buy a couple more and return them if they don't help.

    I tested my RAM in another computer and it passed with flying colors. I've read the GA-EP45-DS3L is very picky about what RAM it works with, but I don't know what to alter in BIOS to fix the problem. I've seen someone with the exact same set-up as mine, so I know it's possible.

    Also, if RAM compatability really is the issue, what reliable RAM could I replace mine with to ensure smooth sailing?

    Would you mind posting your complete memory timing settings?
