Rating: 5/5 Well sorted selector, quality product. January 28, 2016 I've been ordering from OWC for years, across three different Macs, and always have been happy with the products and more happy with the website, its Mac orientation makes it easy to select the right products for the machine being repaired. This time, in the selection of Ram to boost my latest Mac Pro, it was just a matter of pulling the trigger as the website took me straight to correct size and the price point I was comfortable with. Well done, all around!

Rating: 5/5 Breathing New Life Into A Mid-2010 Mac Pro September 27, 2015 My mid-2010 Mac Pro quad core that I use for HD video editing started experiencing stability issues recently. I decided to have a processor upgrade (dual 3.6 GHz six core processors), bump the RAM up from 24 GB to 32 GB, pull the two original graphics cards and upgrade to a modded MacVidCard Nvidia GTX-780 6 GB card, add dual Solid State internal drives and upgrade from OS Lion to OS Mavericks. The result? A super fast, very stable and reliable video editing platform with Adobe Premiere Pro. Money well spent.

Rating: 5/5 8-GB RAM for Mac Pro mid-2010 April 21, 2015 I wanted to expand my 8 GB RAM to 16 GB and this product has worked well. I have not put this new memory through any special tests but upon restarting the Mac Pro, it recognized all the memory without a glitch and has been working well since I installed it (unit remains powered on). I pretty much new how to add it but so be safe I viewed the OWC on-line videos and the installation was easy. I have only purchased additional RAM for my Mac computers over the years from OWC and as best I can remember, I have never had a problem yet.

Rating: 5/5 Happy with this product June 22, 2014 Satisfied with the product, but the RAM was not packed securely. The two RAM sticks were inside of a plastic case and were not secured within the case.

Rating: 5/5 Excellent value December 22, 2013 The DIMMs were very well packaged and shipped promptly. After installation, they were immediately recognized on startup and are working flawlessly. The OWC price is just over half the price of comparable memory and I suspect the quality is comparable. Plus OWC knows Macs intimately.
