Rating: 5/5 This is a great deal! August 18, 2012 I bought this to replace memory that was damaged during a power fluctuation (a UPS is next on the list). I've purchased Mac Pro memory from OWC before (way less expensive than mfg. original) and never had a problem with it. It's completely 100% compatible - "set it and forget it". My only afterthought is maybe I should have ordered the 32GB - the price is right.

I would recommend this item to a friend!
