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

I had ordered OWC prior and the iMAC hated that idea. The Crucial memory installed flawlessly and no problems since.

Perfecta

Fast service and worked without problems. Great. I would recommend this memory and supplier

Like many others it didn’t work with the first installation but just pulled them out, changed positions and it was fine. 5 minutes. Doubled my ram from 32 to 64 and now I can run the newest Photoshop without any issues. The first 32 I installed two years ago still working well, but with every PS and affiliated program upgrade it seems I need to crank it up.

Installed additional 32 gb of ram in my iMac and it only took me 5 minutes. Performs as advertised. No glitches. Not my usual results.. could not be happier.

I installed the modules on a brand new 2019 iMac. Super fast and best of all, SUPER CHEAP compared to Apple store.

Took some re-arranging of the RAM slots - but works perfectly.

What can I say, I paid for them, put them in and my computer shows what is suppose to be in it and it runs way faster.

Works great with my 5K iMac. No problems

I installed it myself and it was fairly easy. It worked great. My main concern was that I would order the wrong thing but the specifications in the description were right on.
