Rating: 5/5 Incredible speed of Delivery! April 10, 2017 Arrived super fast, was easy to install and arrived in less than half the time stated. Can't really say how much better than "Exceeding Expectations" this order was. i will be ordering the rest of the memory module Is need with you when possible from now on, especially since your memory costs about 1/3rd that of Apple's normal cost margins.

Rating: 5/5 Memory for iMac April 3, 2017 I wanted to increase the memory in my iMac to 32GB. It is very important to have the exact specifications that the computer requires so that you match the specs of the memory that came from Apple. This memory matches exactly. Installation was extremely easy. It took me less than 5 minutes to install. Once installed, I turned on the computer and checked the memory which showed I now had 32 GB. I can tell the difference when opening 3 or more photo editing apps or Final Cut Pro X. These ran faster as far as rendering photos and videos. I would recommend upgrading memory if you are using apps that are demanding in memory.

Rating: 5/5 Seems to be doing the job March 20, 2017 Kicked my new iMac up to 24GB memory from the original 8. Because of problems with the older iMac I'm in the habit of leaving "Activity Monitor" on most of the time. Hadn't thought much about it but Safari, with a couple of windows and several tabs each quickly utilizes memory and often will see memory used at 16 or more so this was definitely a good start for me. Everything seems to run smoothly.

Rating: 5/5 Great product!! March 2, 2017 Worked on my late 2015 27" iMac with no problem. I doubles my memory from 84GB to 16 GB. I didn't want to leave the original memory in the mac since it was two different brands. It probably wouldn't have had a problem but my experience told me to stick with one brand of the exact same kind. Works beautifully!!!!!

Rating: 5/5 Quality RAM, Excellent Performance January 22, 2017 I was between ordering 32Gb Crucial or OWC RAM for my new iMAC. I opted for the OWC based on the positive reviews and the cost being a few dollars less than Crucial.

The product arrived very quickly, was well packaged and the RAM was a perfect fit.

I have yet to put the RAM through much more than normal use, but the speed of the iMAC went from very fast to noticeably faster.

I'd certainly purchase more OWC RAM based on my experience thus far with the product.

Reviewer: MacDaveinSactown
Rating: 5/5 Excellent Upgrade January 22, 2017 I bought a new iMac with the standard 8 GB of RAM. I bought another 8 from OWC almost immediately, rather than buying it from Apple. I've used OWC in the past and I couldn't be happier. The products and customer service are outstanding. Installation was easy. OWC had written instructions and, of course, there are many 'how to' videos on YouTube. I really wish Apple hadn't made the decision to solder RAM to the logic boards in their newer laptops and Mac Mini. I would love to be able to add RAM to those as well.

Rating: 5/5 The simplest memory upgrade ever. January 12, 2017 I decide to upgrade the memory in my iMac. Reviewed what was available for my model and bought the memory set, 2 x8 gig, bringing my total to 24. Opening the back and installing was a couple of minutes and back up and running. Never disappointed with anything from OWC.
