    Have a quick ram question.

    I currently have 4gb in my 2008 mac pro 4x1gb sticks. I have just been given another 2 1gb sticks, is it ok to add these as well so I have 6x1GB sticks?

    I ask as I don't see this config on the apple website only 4/8/16 etc...

    Many thanks

    If they are the same type of memory and installed in pairs, it should work. The web site combinations are because they just stick to the same kind rather than mixing sizes to go halfway between. You'll be fine. I have 1GB and 2GB sticks in my Mac Pro.

    I agree, I think you should be fine.

    For further information in general, please check out our RAM Guides. :cool:

    Thanks very much for the advice :)

    Just to confirm i would put

    1gb(module 1) top riser 1 - 1gb(module 1) bottom riser 1
    1gb(module 2) top riser 2 - 1gb(module 2) bottom riser 2

    as they are already.

    and then the new ones in

    1gb(module 3) top riser 3 - 1gb(module 2) bottom riser 3

    Correct?

    Check the manual. I think there is a insertion order diagram inside of the door panel too.

    The Guides I linked to above will tell you.

    Page 46 of the Apple Manual...
    Which describes the same configuration as seen at OWC, which is in better detail;
    Memory Location Quick-Sheet

    Matched pairs are installed ON THE SAME RISER in a CERTAIN Order.
