- Current Mac OS X versions are unable to utilize more then 96GB RAM due to an operating system limitation. 128GB can be fully utilized by a 2009-2010 Mac Pro if running Boot Camp with 64-bit versions of Windows XP and later as well as with 64-bit versions of Linux.
- Although limited to physically utilizing a maximum of 3GB, there is a performance benefit due to 128 Bit addressing when 4GB (2GB x 2 Matched set) is installed.
