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.
This kit is compatible with a dual processor (8-core) Mac Pro models ONLY. While single processor (Quad-core) Mac Pro models do have 4 memory slots available, This kit is not compatible due to an OS system limitation.
OS X versions prior to 10.9 Mavericks are unable to utilize more than 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.
