If your Mid 2012 Mac Pro shipped with 1333Hz RAM it will be fully compatible with the computer. Note that some Mid 2012 models shipped with 1066MHz RAM. You can verify which your system uses by opening the System Information application in the Utilities folder.

question

Is it compatible with 2009 Mac Pro?
Asked by: Anonymous
To find the right type of Memory for your Computer go to Google and type Memory selector, Memory finder without quotes. Make a note of the specs come back here and select the Megabytes you need. Would be a good idea if B&H implement a Memory Selector Tool in near future. Note : Some Memory tools would tell you the Max of megabytes you Computer would accept or you can check your Computer Manufacture specs.
