  1. Will DDR 400 RAM work in a DDR2 800 standard motherboard?
    Just curious if those new DD2 motherboard are backwards compatible for that older type of memory.

    Thanks

    Welcome to Techspot!

    It won't work @ all, because DDR400 RAM has 184 pins, and DDR2 RAM has 240 pins, and uses less voltage than DDR.

    Regards :)

    NO. Read the installing RAM and upgrading guide in the guides forum.
