> 3 dayPerfect for my iMac Retina 5K 27inch 2017 model. Removed the old ram and put the new ram in its place and put the old ram in the empty slots. Now have 40gb and everything runs great. Fast shipping to Aus.

> 3 dayEasy to install and greatly sped up my 2017 27 iMac. It originally had 8gb, and I added this 16gb bringing the total to 24gb. Installation was very simple - I had it installed and running w/in 15 minutes of it arriving at my door. Id recommend as its much cheaper than getting from Apple, and the install is very simple. Works perfectly.

Greater than one weekBought a new iMac because my old one gave out. Purchased the standard 8GB from Apple, and bought this RAM rather than pay Apple twice as much. I took out the 8GB and put in the 32GB before I even turned the new Mac on. Absolutely no issues. Mac powered on with no trouble. The reason I took out the 8GB and simply left in the 32GB was because I read several reviewers who ran Geekbench tests on their systems, testing the 32GB (2 by 16) and 40GB (2 by 8 and 2 by 16) and the single core and multi core scores were higher with the 32GB RAM. Its not much of a difference, but I suggest you run some tests on your system to determine which is faster.

> 3 daySo far, my computer is sooooo much more powerful. I have a 2017 iMac Retina 5k, that came with 2x 4gb memory cards and it was not fast enough to do my digital painting while using quicktime to record my screen. Anyway, I finally got the cards in the right order so that the memory cards were in the right order for my computer to use the 16gb cards first. I was not sure if I had done it right because when I tried to turn my computer on nothing happened.... but it was just detecting the memory I guess. so just be patient after you put your memory in.

> 3 daySo I love Apple, but their memory prices are too high. For the $1,000.00 they wanted to charge for a 64G iMac, this Crucial memory was about 27% of the cost. Went in easy, fired right up, no worries at all. Ive used Crucial in my last two iMacs and Ive never had any issues. Solid investment.
