Rating: 5/5 New life for my 2011 iMac September 30, 2016 My upgrade from 4GB to 12 GB has breathed new life into my aging iMac. Memory pressure is in the green zone, compressed memory is way down as is swap.

I would recommend this item to a friend!

Rating: 5/5 Easy peasy double my memory October 30, 2015 After my purchase of the 2011 iMac from OWC a halloween special put two sticks of memory in my hand ready to pop in and bring my iMac up to 16 GB. I had seen the instruction video but just for safety sake saw it again least I had forgot something. Well, what I forgot is where I put my philips head screwdriver! Using a multi-tool I successfully removed the cover and removed the existing memory just to see where the notch was. Sliding in each module and giving it that last push reminded me how reluctant I was the first time placing memory sticks. Haven't broken one and did not this time. All sticks in, cover on and everything placed back for the big test. Powered up and clicked About This Mac... good says 16 GB, and click Memory... all four slots show memory in use! Great job my people at Other World Computing! No issues, no problems and another pleasant upgrade experience handled with the care and forethought of OWC!

I would recommend this item to a friend!
