    Hi, I’m thinking of buying the 3.33GHz 6-Core Intel Xeon “Westmere” Mac pro but I'm confused as to how much Ram I can put in it.

    According to Apple it supports 16GB of Ram . I quote:

    • The single-processor Mac Pro supports up to 16GB of DDR3 ECC SDRAM memory in four slots. Choose more memory to improve overall system performance.


    However on the crucial website it says:

    Apple Mac Pro Quad-Core MC250LL/A Mid 2010 Desktop/PC.

    • “External Drive Bays: 2 x 5.25"
    • Internal Drive Bays: 4 x 3.5"
    • Maximum Memory: 32768MB
    • Slots: 4 (4 banks of 1)
    • Standard Memory: 3072MB removable
    • USB Support: 2.x Compliant

    So how much RAM can I put in 16GB or 32GB?

    Apologies if this has been posted before but I’m really confused!

    The maximum is 16GB if you go through Apple because they only sell 4gb sticks.

    If the 2010 Mac Pro is the same as the 2009 which it most likely is, it'll accept 8gb sticks with is available from places like OWC.

    So the "true" maximum is 32gb.

    However, the technical maximum is probably 96gb's :p

    This is all with 4 sticks.

    Thanks! So I should be able to fit 4 x 8GB sticks then.

    Is it possible to add 2x 8GB sticks to begin with and then and the other 2 at a later date so I can spread the cost?

    You can replace the 3x1GB with 2x8GB. Can't mix them.
