Can I use memory modules with 128GB capacity on Apple's Mac Pro late 2013? Category : Setup / Operation The late 2013 Apple Mac Pro supports up to 128GB of RAM. We suggest using Transcend JetMemory upgrade kit: TS128GJMA534P.Note that due to Intel's Xeon CPU limitation, the system will run at 1066Mhz when installed a quad rank memory module. Is the answer helpful? Related DRAM Installation Procedures Why does Transcend include the Proposition 65 warning? Can I use 4GB FB-DIMM on Apple Mac Pro MA356LL/A (2006)?
