Rating: 5/5Don't panic after installing your RAM!August 20, 2018I just bought a new 27" iMac 5K and added the OWC 32 GB RAM kit to it before I even plugged it in. The process is very quick and very easy -- it took maybe two or three minutes. No problem -- but be aware. The machine would not turn on when I first plugged it in, so I looked up the symptoms on my phone and was relieved to discover that it's normal. Newer Macs have to initialize any RAM when it is first installed or the RAM configuration is changed. I just followed the recommended routine -- unplug the machine, hold down the I/0 button for at least ten seconds, then plug it in and hold the button in again until it starts up. Everything boots properly and you're off and running. As I don't buy new Macs often, I was unaware of this change. But panic averted, I have a new machine with plenty of RAM and everything working just the way it should! I would recommend this item to a friend!Customer Videos:

Rating: 5/532.0GB OWC Memory Upgrade Kit for iMac 27" 2017 with Retina 5KJune 6, 2018First of all, I have been a Macsales customer since 1990's. Everything I have purchased from them worked perfectly. I have a new iMac 27" 2017 5K w/ 3.4 processor. Like all iMacs it came w/ 8GB stock memory which is not adequate to run today's software. So, I purchased 32GB upgrade (2x16). Now I have a total of 40GB memory (32+8=40). It is a good idea to get two 16GB's because if you need to upgrade it to 64GB maximum in the future you can add just another pair of 2 x16 memory! Installation was really easy. Just unplug your iMac, put it on a soft surface screen face down. Press the memory cabinet cover pop up button down, slide in your new memory sticks, power up your computer and you're done. Note that you need to press the button really hard in order to pop up the cover. I used wood chopsticks to not to scratch my computer. Also, make sure to slide your memory in a correct way. It should be firmly in place and should not move. Today is my second day after upgrade and I am very happy w/ awesome performance. I would recommend this item to a friend!Customer Videos:

Rating: 5/5No Brainer!May 1, 2018I honestly feel this is a no brainer! I boosted my iMac from 8Gb to 16Gb with 2X4Gb chips from OWC. I then decided it was necessary to just get a 32Gb set to boost to 40Gb. I do not regret this one bit and my iMac flies! Don't waste money buying the ram from Apple! I'm almost tempted to get another 32Gb from OWC and just max out the iMac. I would recommend this item to a friend!Customer Videos:

Rating: 5/5You can't have too much RAM!April 25, 2018Bought a new iMac with minimum RAM fully intending to use third-party memory sticks. I have always had great experiences with OWC and found their 16GB modules were my best choice. Installation is a breeze and the chip has performed flawlessly!

Rating: 5/5Great productMarch 11, 2018Not really much to say about this. The shipping was extremely quick, the RAM arrived before my 2017 iMac which I was hoping for. Not much else to say great product, good company for what I required. I would recommend this item to a friend!Customer Videos:

Rating: 5/5Good Product, Good ServiceMarch 8, 2018Been using Other World Computing since forever and never had a problem. Way back in the '90's they were about the only people who sold upgrades for Macs and that's what got me started. So they still go a good job and their products are quality. So I still come back.

Rating: 5/5Excellent product and priceMarch 2, 2018I bought a 32-Gb upgrade for my shiny new 2017 retina iMac and I could not be happier with the purchase... now my iMac has 40 Gb of RAM, the performance has improved a lot, especially when executing virtual machines in Parallels and apps that need lots of memory to perform well (e.g., analyzing large datasets in R).

Rating: 5/5The Best Thing I could ever have done for my MacFebruary 18, 2018I just bought a new iMac with 32 gigs memory. I wanted 64 but Apple talked me out of it (they are so stupid and dare I say it greedy as they won't upgrade you after the fact presupposing you'll just pop down another 5k to buy a new machine). I contacted Macsales and a 64 gig ram set was less thsn if I had ordered it from Apple. Apple made me feel this was hard to do. It was a breeze. I now have a 64 gig iMac with an SSD drive (be careful as Apple made all the SSD machines AFPS and it came out a year too soon) and my computer is purring. It has never run so well no thanks to Apple.
I'd heartily recommend the 64 gig ram upgrade from Macsales who notices too much paging activity or RAM flushing. Welcome to the new Apple far more sinister than the old Microsoft ever was thanks to Tim Cook.
