I've installed two of these with my 2017 iMac 5K 27inch desktop. Around a month now but no issue with. Working perfectly. I recommend this for iMac user.

Excellent RAM. 100 compatible with new 2017 Apple iMac 5K 27 inch computer. Great price. Same as on Amazon in the USA.

Thank you so much.

No problems. I got at a very very good deal. I have had it for about 3 weeks now and it has performed amazingly.

Good to be able to upgrade memory - making a good laptop buy better.
