IMPORTANT OWC NOTE:
OS X versions prior to 10.9 Mavericks are unable to utilize more then 96GB 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 system profiler but only up to 32GB will be actively used by the computer.
