Rating: 5/5 With 128Gig I can rule the world! November 29, 2016 Little early to say since I just installed it but install was easy. No problems as yet. If it hasn't failed yet, it probably won't. That said, I have bought other RAM upgrades from MacSales and have not had a problem

Rating: 5/5 OWC 128 GB upgrade to Mac Pro 6.1 August 24, 2015 When I purchased the upgrade RAM of 128GB for my Mac Pro 6.1 I received excellent technical support from OWC, The product arrived very quick on my house and I installed the memory according to OWC procedure. When restarting my Mac I was surprised about the increase in responses for all my applications, start up times where in some case half of what I had before (64GB). I am very happy about the decision to buy the product from OWC. Very responsive support and a very good product for my Mac.
