    Did you have to raise MCH Core for one stick to work?

    for 1 stick

    or 2 gig single channel,

    i could even just boot with default setting. load optimized.

    so no tweaking was nessary to boot with 1.8v at default setting.

    Try lowering your MCH Core then, 1.05 or below see how this goes.

    i never had this problem with ep43... i might return ep45 and get that..... only thing i didn't like about ep43 was lack of raid.. and the temp of norht bridge..

    Try 1v and 0.95v if no go. It's not the P45 some boards need more some less, might be compatibility issue with the memory.
    I didn't understand, does dual channel work with default settings or does not work at all?

    Seems to be a problem with the board.
    Befor you going to get an RMA try the long version of clearing CMOS described in the second part of this post.

    I agree with Chike.
    It appears that your mobo is defective.
    Definitely try the long version of CMOS clearing in the bios flashing guide.

    Let us know how it turns out.
