I found this information from Everymac.com site - Apple officially supports 64 GB of RAM in this model, but as first noted by OWC, it actually can support 96 GB running Mac OS X 10.6 or 10.7, and up to 128 GB. When running OS X 10.9 "Mavericks" or later, this model is capable of using 128 GB of RAM, but this is limited to 96 GB of usable RAM when running earlier versions of the operating system.
