    Rating: 5/5 Computer memory works flawlessly (wish mine did) August 25, 2018 I doubled the memory in my 2013 MacPro by getting two 16GB sticks from OWC. They work like a charm. OWC's buyback program for the old memory (4 4GB sticks) made it even better. I'm doing some heavy computations in a program that stores all the data in memory, for speed. No fear now that I'll run out if I get a bigger dataset. Thanks OWC! (I've been a customer for years)

    Rating: 5/5 A great deal December 17, 2017 Glad to find an option for upgrading the RAM in my Mac Pro that was cheaper than the Apple option.

It was easy to fine and buy, easy to see how to install it using the MacSales video, and the price was right. It arrived quickly and I installed it in a few minutes.

    Rating: 5/5 Totally worth it !!! June 20, 2017 No more complains that Mac Pro 2013 is slow. I have decided to upgrade memory after reading a lot from users confirming significant performance boost after the upgrade. So, decided on 64GB package from mac sales site. OWC proven to be great components supplier for Macs and price wise its much better deal. The whole buying experience was excellent and I got follow up call from mac sales as well to check on things from delivery and procedure point of view. 5* service, MacSales ! I have put step by step upgrade process. If you had similar experience, please let me know. If in questions or thinking about upgrading or buying new one, ask and you shall receive. I see that machine is way faster and move dynamic now. Should have thought about this earlier :) !

    Rating: 5/5 Great decision. November 8, 2016 I make music running a Mac Pro as the brains of the system and it was running ok on the 16GB of ram. I decided to move from 16GB to 64GB and what a difference. This product was easy to install and was a solid piece of equipment. Just looking at my memory usage now, and my system is currently using 15 GB of ram with just the web browser open? This tells me that I no longer have to purge the ram as there is plenty to spare ram available. I'm ready for any updates these DAW companies are ready to come up with and it one less thing that I have to worry about in the near future.

    Rating: 5/5 The only option and they work July 28, 2016 I looked around and everybody on the internet seem to think that apple charges a lot for ram upgrades and that you can buy cheaper options elsewhere. Partially true.

    Even tho there are cheaper options for ECC ram, none other have the thermal sensors. So why spend 3.5k+ for a mac designed to use 1 fan to control the temperature and then put RAM that the computer can't monitor.

    I might be wrong on this but this for me were the only logical option and I'm pleased that they worked as expected.

    Rating: 4/5 For months my Mac Pro crashed, RAM scans didn't show any issues January 17, 2016 A couple months after I bought this RAM my Mac Pro crashed, crashed and crashed constantly for months. I took it in to Apple thinking it was something else, they checked it in, tested it, everything pass with flying colors, even the RAM. It was excruciating working on my Mac with so many constant crashes. Then one day I decided to call OWC to ask to replace the RAM, they did, and my Mac Pro stopped crashing. I was torn to give it 3 or 4 stars, because I like OWC, but never had something given me so many crashes like this on any of my Macs for over 10 years, and I couldn't believe that it would even pass RAM tests, until I decided to get it replaced. I guess this was a quality issue at the end, but it caused me a lot of headaches and wasted time thinking it was my Mac Pro with the issues.
