Rating: 4/5 Best third party memory for Mac Pro out there. July 3, 2016 I would definitely recommend OWC RAM modules. In fact I would recommend not buying the Apple's OEM RAM just based on value and expansion capacity. Order the least amount of default RAM possible then swap out for OWC RAM. That's what I did and I am pleased with the product and decision.

I would recommend this item to a friend!
