Memory suggestions that is compatible with my machine? (Kingston 4GB DDR3 1333 ECC Memory for Mac Pro Model KTA-MP1333/4G)

Mac Pro, Mac OS X (10.6.5), 8 GB 1066 MHz DDR3

    How much do you have now, 4 x 2GB?

    do you need 24GB to handle work in CS5?

    2009 model year? MacPro4,1?


    Mac Pro Memory 1066


    Crucial and Kingston are excellent choices especially for UK.


    Kits of three triple channel - use to be that you couldn't mix 4GB and smaller, same holds true for 8's, and you might want a pair of 2 x 8GB


    OWC has a rebate / buy back of Apple memory


    RAM timing is determined by the processor's memory controller and Apple firmware, and you may be able to use 1333 but it may not run @ that speed (check OWC page)

    Thanks for the response.

    I have a MacPro 5,1 bought late last year.

    I have 4x2GB now.

    Painter and Photoshop running slow. Especially Painter.

    Then I assume you have a single processor and 4 DIMM slots, 3 x 8GB would be ideal but won't mix with what you have.


    I wouldn't bother with 4GB DIMMs, even if you go with 2 x 8GB for now.


    SSD for boot drive is a nice. And look at scratch, disable Spotlight for scratch, all the usual tips and tricks optimizing photoshop.  A fast boot drive is one upgrade most feel returns a great overall improvement in performance.

    Sorry, no, I have the dual so it looks like I should have 8 slots but I haven't looked yet. I'm thinking just 4 more 2GB may be enough of a boost for now.

    I am in the same page as Dareell, I am planning on upgrading my memory from 6GB. I have a Mid 2010 Mac Pro 5,1, and I am curious if its good to max it at 16GB of RAM. I am a recording engineer (and PC gamer [bootcamp with Win 7 x64 and Radeon HD 5870]) and I am curious if maxing it out WILL NOT make a performance issue.


    What is your suggestion?
