    To be honest, I don't think you can do that. Most newer boards will be setup for Dual Channel which requires matched pairs of RAM to work properly.

    I might be wrong (and I'm sure someone will correct me if I am wrong)..

    Dual channel RAM does require essentially identical sticks of RAM to work, though you can run non-identical RAM sticks so long as they're not in the dual channel setup.

    However, many motherboards and chipsets just don't like mixing sizes of RAM at all and you may well continue to get problems from this.

    Best use RAM sticks of the same size. If possible use the same spec too, if you want dual channel to work, which is recommended.
