Out of the factory the Mac Pro comes with a max configuration of 64GB of RAM, and according to Apple that’s as far as you will be able to go with the machine, however Transcend have recently unproven that with the release of a new set of 32GB memory stick,s which when combined into the four sections of the Mac Pro’s RAM compactly, the user can get a total of 128GB of RAM.
Transcend say that these new DDRM3 RIDMM modules are “100 per cent compatible” with the new Mac Pro despite the maximum amount that Apple claim in their spec sheet.
“The new Mac Pro 2013 is advertised to support up to 64GB of memory, and we understand that pro users running applications that place high demands on RAM have a need to meet and most likely exceed this threshold,” said Transcend’s Director of R&D Angus Wu.
“For this reason, we have developed and fully tested higher density modules to give users the option of raising their Mac Pro system memory to the advertised 64GB right up to 128GB.”
Transcend are yet to announce any information for the pricing or availability of the modules, but you can probably expect them to be quite costly when purchased in multiples.
