    I understand that when installing ram in the new 2008 mac pro. You can achieve a slight increase in speed. By installing your modules in sets of four, of the same size.

    Does this mean that once I have my first set of four. That all additional sets of for have to be the same type of the first. Or can I mix and match sets of four.

    Will 4 1-gig chips, and a second set consisting of 4 2-gig chips. Still allow me to take advantage of the speed increase of 256-bit access.

    4 x 2 GB and 4 x 1 GB will have 256 bit access across all modules -- as long as they are installed in the correct slots

    A1 A2 B1 B2 for the 2 GB
    A3 A4 B3 B4 for the 1 GB
