Crucial RAM 64GB Kit (2x32GB) DDR4 2666 MHz CL19 Memory for Mac CT2K32G4S266M

Good quality

It is good but I find that I buy the wrong speed. it should be MT2666 instead of MT2400 so I returned this one

I ordered a new 2018 iMac 3.5 Ghz Core i5 (Retina 5K, 27-inch) with a standard 8GB Ram and a 1TB SSD for a total price tag of $3,387.89 with tax (including Apple Care, USB-C VGA Multiport Adopter and MS Office Home 2016 for Mac). Had I chosen the configuration with a 32GB RAM, it would have added $600 more + tax. So I decided instead to order a compatible 32 GB Kit (16GB x 2) from Crucial which cost me only $338.30 (Tax included). Thats a savings of almost or about $300. Adding the 32GB RAM took only less than 3 minutes to complete. It was a no brainer. The best part is that my new iMac is now operating blazingly fast with a total of 40 GB RAM!

Installed on my msi laptop without any problems. Now I got 32 gigs instead of 16. Was needed for video editing.

Brought some life to my laptop

Thank you for making and selling these!! Our basic but expensive Mac was getting laggy when working on large photoshop or Adobe files. We didn’t want to pay $400+ plus for an apple RAM card and we’re so happy when we found these.

Holy Multiple Windows at the same time Batman!!!!!!!! :). Wooooow!!!!! Worked as advertised :)

Great RAM stick. Used it in a dell 5000 series and works beautifully.

UPDATE: Changing my rating from 2 to 5 stars. This memory IS comparable with the 8GB Hynix Mac memory. You have to fully remove the original memory, install this kit in the first two rows and then install the original Mac memory in the last two rows. Installing the chip in an alternating pattern like the original memory is installed will not work. Hope that helps!

Review is for the 16GBx2 DDR4 Dual Rank.
