Rating: 5/5 Good match April 18, 2016 I ordered a 27" iMac with Retina display (i7) with some extra memory. The computer balked and froze and otherwise was a problem. Turns out the chips were clocked at 1866 mHz, when they should have been 1867 mHz. I ordered from OWC and they sent me the correctly clocked chips. No problems with the computer since then.

Rating: 5/5 Always satisfied with OWC RAM January 23, 2016 I've been buying my RAM from OWC for over 20 years and I've never been disappointed. I've never gotten a bad stick of RAM that I recall, and these were no exception. I bought this for my Mom's 2008 iMac. So far she's quite satisfied with the improvement in performance on her computer which was getting frustratingly slow after recent OS updates.

Rating: 5/5 OWC to the Rescue April 3, 2015 Where else in the world will you find the last DIMMs in the world to update a seven-year-old computer - and the videos to confirm that you are doing it the right way when that seven-year-old computer has frozen shut it's cover plates? Thanks, OWC, for adding a couple of more years to the useful life of this computer!

Rating: 5/5 Great Experience January 5, 2015 OWC made it clear which memory to buy for my iMac early 2008 computer. The price was comparable to what I found on Amazon for same specs. The memory came superfast and in excellent packaging (easy to open, well protected). No problems with installation.

Great Experience! I highly recommend OWC for people who want a hassle free computer memory purchase.

Rating: 5/5 Good pricing, reliable product October 9, 2014 This is the second such iMac memory card I've ordered: one was for a family member, the other for a friend. In both cases, the pricing was good, the shipping was affordable (USPS to Canada), and the product has worked reliably. OWC continues to be a reliable and responsive supplier.

Rating: 5/5 Easy RAM upgrade August 15, 2013 I struggled with an ever slowing iMac and discovered by a process of elimination that I was wholefully lacking RAM capacity. I happened upon your video on how to add RAM decided I could do it easier than I could have someone else do it so i ordered a memory card from you late on Tuesday afternoon. The card arrived Thursday and is now installed and it was actually as easy as the video portrayed. The Mac is up and running properly, that is, fast again. Great service, easy to understand helpful process to order and install.

Rating: 5/5 Product was like it was described May 31, 2013 I received product quickly and in excellent condition. I used the online video guide for reference then installed part in my iMac myself which was very easy and quick - I am a 62 yr old woman with self taught computer experience - I am happy with performance improvements and will purchase another memory module from OWC in the future.

Rating: 5/5 Stability is everything April 3, 2013 When I first received my MacBook, the quanity of RAM was far too meager. That wasn't unusual about Apple products in 2009 or in previous years.

I got the 2 GB stick from a trusted company, OWC, because I'd had good experience with them. I considered buying the name brand RAM from them, but felt that they wouldn't put their name on it if it had defective components, or give a great guarantee.

My faith in the product has been justified with almost 3.5 years of smooth, glitch-free service.

Rating: 5/5 iMac help November 30, 2012 In this case, I had an iMac with an original 1GB of memory. This particular machine has two memory slots. It's a pretty easy job, just take out one tiny Phillips screw, and the slots are right there. I added one 2GB DIMM, bringing the RAM up to 3GB. It made a big difference, as my Activity Monitor showed the machine as RAM starved. This machine got a copy of Windows 7 on Boot Camp, and I changed to Parallels 8. Having the two OS's run side by side would be maddening with only 1 GB or RAM, maybe not even possible. This forces the machine to start to write memory onto the hard drive, really slowing things down. After adding the 2 GB, performance noticeably improved. Of course, I could have opted for even more RAM, but was happy with the yield I got from just this one chip. I'm only running static type applications, like boring tax programs, no games. As far as OWC memory goes, I've used it in other machines in the past, never had any problems at all.
