    I have a riser A/B question. I have installed an extra 4g (2x2G) memory to my factory installed 1G. Does it matter that the 1G (2x512) pair is on Riser A and the second pair on riser b?

    Do you have the 2008 Mac Pro? These come with 2GB factory installed (2 x 1GB). In any case, you should have the factory installed pair in one riser, and the new pair in another riser (slots 1 & 2 on each). It sounds as though you have installed it correctly.

    As far as I'm aware, the memory installation is the same for the older and new Mac Pro's with 2 exceptions: when only 1 pair of modules are installed they should be in slots 1 of risers A & B on the new Mac Pro but in slots 1 & 2 of Riser A on the old Mac Pro; the other difference is that the new Mac Pro supports 4GB modules.

    Thanks
    It is a 2007 MacPro. I am awaiting Aperture to arrive this week to see if there is a detectable slowing. Everyone seems to praise its speed.

    Hi!

    I have a Mac Pro (october 2006) with 2GB RAM (4x512).

    I want to add 2x1GB, do you think this configuration is correct?:

    Riser A 1: 1 GB (crucial)
    Riser A 2: 1 GB (crucial)
    Riser A 3: 512 MB (apple)
    Riser A 4: 512 MB (apple)

    Riser B 1: 512 MB (apple)
    Riser B 2: 512 MB (apple)
    Riser B 3: empty
    Riser B 4: empty

    Or would be better this other (as recomends this document and does not reccomend this other document)?:

    Riser A 1: 1 GB
    Riser A 2: 1 GB
    Riser A 3: empty
    Riser A 4: empty

    Riser B 1: 512 MB
    Riser B 2: 512 MB
    Riser B 3: 512 MB
    Riser B 4: 512 MB

    I'm lost. Thanks in advance!

    Either, it doesn't matter. What matters the most is to fill up all 8 DIMM slots though.
