My new Mac Pro tech specs state 1066Mhz speed RAM but the only RAM Apple sells is 1333Mhz.

Hi,
I recently purchased a Mac Pro Quad Core 2.8 Ghz with 1Gb RAM but know realize I need more RAM. The Mac Pro tech specs state 1066Mhz speed RAM but the only RAM Apple sells is 1333Mhz. Can this model benefit from the speed increase?

Thanks,
Bob

    Hi,

    I just want to share my experience with you:

    I did upgrade my Mid2010 Macbook Pro from 4GB RAM DDR 1066Mhz to 8 GBRAM DDR 1333Mhz. It does work but just at 1066Mhz speed.

  • It seems that for Mid 2010 Mac Pros, some of them have 1066MHz RAM instead of 1333MHz. While I don't have enough information to guarantee that your computer supports the faster RAM, it is likely. I'd advise contacting Apple at 1-800-MY-APPLE (1-800-692-7753) and asking a tech as they should have that information. The faster RAM should work in your computer, it will just run slower. DIMMS must be purchased in even numbers to work properly. One module goes in riser A while the other one goes in the same number slot on riser B.

    FYI: The Mac Pro 5,1 uses 240-Pin PC3-10600E (DDR3 ECC SDRAM). This is not standard desktop memory but workstation/server memory.
