Rating: 5/5 Perfect Memory July 9, 2017 Couldn't get the 2017 iMac 5K I wanted with 64GB of RAM at the Apple Store...was only available with 8GB. I was willing to pay the premium, but glad I didn't as OWC shipped quickly and the RAM was very well packaged.

It's basically a 5 minute install job, turned off and unplugged, popped open the memory slot and put in the 64GB or RAM from OWC/MacSales.com. Once I turned the machine back on there was a noticeable difference in the snappiness of the OS and Photoshop and Final Cut have been handling the largest of files without any pause.

Thanks OWC for a quality product.

Rating: 5/5 OWC RAMs make adding memory so easy. July 7, 2017 I doubled the RAM memory of my computer and it was so easy and the price was very reasonable. This was the second time I doubled my RAM. I did the same thing with my last computer and it was flawless.

Rating: 5/5 Happy with my RAM July 4, 2017 Just boosted my new 27 inch iMac from the standard 8GB to 24 GB by adding 16GB of MacSales RAM.

Utterly trivial exercise, and everything worked smoothly. Can now happily dedicated a few GB to the 64 bit W10 running in Parallels and still totally enough RAM that the system doesn't break a sweat.

Highly recommended.

Rating: 5/5 Quicker than Apple! And half the price.... July 2, 2017 Being one of the first buyers of the new IMac 2017 in the Netherlands the apple store couldn't supply the 64 gb memory, and delivery time was uncertain...... So I ordered at MacSales, and it was delivered to me in the Netherlands in a few days for half the price!

Rating: 5/5 Easy installation and great price June 30, 2017 Just purchased a 2017 iMAC 5K 27in with 8 GB installed RAM, leaving two slots open. Shipping of RAM was very fast and secure. Installation was a breeze and was a fraction of the price if I had ordered the RAM pre-installed. Incredibly happy with my purchase..

Rating: 5/5 First out of the memory box June 27, 2017 Ordered a new 27-inch iMac from Apple with stock ram. Other World Computing had the new modules within days of Apple's release. Ordered 2 x 8 GB modules and it arrived 3 days before the iMac. Installed the ram before even turning on the computer. Worked like a charm. I've always had great success with OWC ram and this is another winner.
