Rating: 5/5 All is well. November 6, 2014 so I purchased a 12 core mac pro from Apple but didn't want to pay their exorbitant rates for RAM (the machine was already expensive enough!).

So I purchased after market RAM from OWC. Their shipment was prompt, the RAM was easy to install, and I shipped my old RAM back to OWC for a small rebate.

All in all it went smoothly and so far so good around 5 weeks after purchase.

Would recommend.

Rating: 4/5 Room to work! June 28, 2014 Coming from a MacBook Pro to a new MacPro I jumped at the option to load up the machine with 64 gigs of RAM. I don't even think about having the Adobe suite open with FCPX apps open along side email and web browser and iTunes... it all has plenty of room to live and things have been great so far after about 3 weeks. Installation was easy and quick.

Rating: 4/5 great RAM, less expensive than OEM June 22, 2014 Purchased this HUGE set of RAM, it arrived on time. It took a couple of tries to get it seated properly before the new Mac Pro saw all 64GB, though it's not at all clear that it's the RAM or the computer. As of now, a month in, it runs flawlessly. I chose NOT to send the OEM RAM for a rebate since should there be a problem, the OEM might not be willing to deal with it. If I have the original RAM, I can just pop it back in. Excellent instructions for installation.

Rating: 5/5 Reliable RAM At A Great Price June 20, 2014 I purchased the 64GB RAM package for my new late-2013 Mac Pro. OWC's price and their standing behind their product made this an easy decision. Installation was quick and without any hassle..
