Rating: 5/5 worked flawlessly for 2 years May 3, 2015 I had this memory in my dual-six Mac Pro for two years and it worked flawlessly. I have replaced it with larger chips since I was starting to use up the 24G of ram.

Rating: 5/5 Great product. Working just fine. February 17, 2015 OWC Staff was more than patient with me, as I had many many questions about memory configurations and what my best options were. On my BTO Mac Pro 12-core, the configurations and options are different. And they answered all my questions before I made the purchase.

Rating: 5/5 Excellent Service and Products May 8, 2014 The RAM modules arrived earlier than expected at my home in Finland, they were well packed, and passed all tests (including 24 hours of Memtest without a single error). (A local dealer wanted almost double the price for similar products - including VAT and shipping) If you have an older Mac Pro, get these.
