Additionally, this memory module is equipped with an Apple Specified Thermal Sensor, which ensures that the RAM maintains a safe thermal operating range.

OS X versions prior to 10.9 Mavericks are unable to utilize more than 96GB of RAM due to an operating system limitation. 128GB can be fully utilized by a 2009-2012 Mac Pro if running OS X 10.9 Mavericks or later, or if running Bootcamp with 64-bit versions of Windows XP and later, as well as with 64-bit versions of Linux
OWC p/n OWC1333D3MPE8GB (8GB modules) and OWC1333D3MPE16G (16GB modules) require that all installed modules be of the same p/n OWC 8GB and/or 16GB modules. Other existing Apple or 3rd party 1GB, 2GB, and 4GB modules are not supported for use with these kits and need to be removed when these modules are added
To utilize over 32GB of memory in your Mac Pro using 10.6.x or greater, you must boot into 64-bit mode. In 32-bit mode, all installed memory will show in the system profiler, but only up to 32GB will be actively used by the computer

will these work in a Mac Pro mid-2012 5.1 6-core machine?
Asked by: Anonymous
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.
