Identical memory in both slots of a bank (sometimes the slots of the bank aren't the same color, check the manual) will enable dual channel operation. 2x1 GB is preferable over 4x512MB as it creates less of a strain on the memory controller and you can avoid many issues by doing it that way, as well as having room for an upgrade later.
