Rating: 5/5 Added 16GB to my new iMac October 31, 2016 Dropped these two RAM modules into my new 5k iMac to supplement the 8GB it came with, for a total of 24GB. It has been running now for over a month with no problems. The most difficult part was getting that little cover on the back of the iMac to pop open!

Rating: 5/5 Works as expected October 23, 2016 When I bought my latest iMac, I immediately upgraded it with 16 GB of extra memory from OWC. While I might have been able to save some money with brand X memory from other web vendors, I lacked confidence that it would really work in my Mac. By buiying memory from OWC, there is no such worry--it just works.

Reviewer: 2fer Location: Central Puerto Rico Age: Over 65 Experience Level: Power User Owned Product: 1-3 months

Rating: 5/5 Simply Easy RAM October 7, 2016 I had ordered a refurb 27" iMac and it had only basic RAM so I ordered a little more from OWC. It arrived the same day as the iMac so I was able to pop it in before ever turning on the computer. That took maybe 5 minutes and as soon as I did turn on the iMac, it showed the total that included the two new RAM modules. I liked that the correct product was matched up at OWC without needing to do all kinds of searching around because I did not have the computer I was ordering the RAM for before I bought it - just needed to know the year and model. They sent the right RAM, right away and it works super. Very happy to know that OWC is so dependable!

Rating: 5/5 These memory modules are perfect for my iMac October 6, 2016 I upgraded my iMac from 16 to 32 gigs of memory. I had 4 4 gig modules and needed to remove them and replace with 4 8 gig modules. I purchased these and received them quickly. I was able to install them on my iMac in about 5 minutes and they were recognized by the iMac upon my reboot and have been running flawlessly since. Having twice as much memory has caused all apps to run faster on my iMac as they can load more code in memory. I would recommend these memory modules to anyone wanting to increase the memory size of their iMac.

Rating: 5/5 Easy ordering, easy installation October 4, 2016 ordered 2x16 GB memory kit for my iMac (17.1; late 2015). The memory card came with regular mail within 10 days (I live in the Netherlands). Installation was very easy. Just follow the on line instructions. The memory was recognised by my iMac, which now has 32GB of internal memory. Works great and much cheaper than original apple memory. Video editing is much faster and smoother than before.

Reviewer: DukeOBass Location: Central Pennsylvania Age: 55-65 Experience Level: Home User Owned Product: 1-3 months

Rating: 5/5 Great so far! September 9, 2016 I purchased a new 5K 27" 4.0 Ghz i7 iMac with 8 GB of Ram in early August. After placing my order for the iMac, I ordered the 4- 8 GB 32GB Ram Kit to load it up when I received the machine. The Ram came about a week before I received the iMac by UPS.

The Ram installation video was helpful and easy to follow. The installation process was very easy and the Mac is running great! This Ram is the exact 1867Mhz spec that Apple uses. While researching, I saw other Ram that only came up to 1866Mhz and lower. It was also a lesser price, but there were also some poor vendor reviews to accompany the lower price on the Ram.

My son has purchased from Other World Computing multiple times in the past and highly recommended them when I talked with him. This was my first experience with Other World and I am impressed!

Rating: 5/5 Excellent product - major instructional video error! September 1, 2016 I'm glad I was prompted by OWC to write a review as it had slipped my mind. The replacement memory card products are uniformly excellent and easily fit the slots in my iMac. The big problem I had, until I figured it out, was the instructional video on OWC's site shows the installation backwards from what actually needs to happen. /The video shows the label facing g you while , in fact, to be properly installed, the labels should face in the OPPOSITE direction. Please fix this?! Otherwise, an excellent value for the money and well supported.

Response from MacSales.com, Marketing September 1, 2016 The video does state clearly to line up the notch in the memory module with the pin in the memory slot regardless of which side of the memory has the labeling.

Rating: 4/5 Got a couple bad DRAM sticks. No problem! August 8, 2016 I ordered a 64GB DRAM set for my iMac, for the same price Apple wanted to charge for 32GB. I DID get a bad batch, which showed multiple RAM errors under extreme load. HOWEVER, customer support was quick and excellent. They paid my return postage and sent me a new batch. Extensive testing over 40 hours shows the entire 64GB is perfect.

Well done!

I would definitely order this again from OWC.
