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

Fits perfectly into my 2019 27” iMac ... definitely improved speed and file loading.

Works great with iMac 27inch 2019.

I purchased a new 27 5K retina iMAC which came with 8GB memory. I installed the Crucial 32GB kit which was a simple 5 min straightforward install into the two vacant memory banks. The TechTool memory test was flawless and applications open and close much faster with the memory boost. It is an essential upgrade to boost performance at excellent savings over Apple prices.

I bought this memory for the new 2017 27” iMac with the i7 processor. Since the Crucial memory selector was did not list this computer, I was a bit concerned about it being the correct match. After an email from Crucial confirming it was the proper memory, I ordered it. When I returned home with my new iMac, I installed the memory and turned it on for the 1st time and everything worked like a charm.

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

I bought a late 2018 Mac Mini on sale for a great price. Apple charges premium $ to upgrade the RAM so I bought a version with standard 8GB RAM. The Mini worked great as it was, but I use it regularly for some things that benefit from more RAM. This SODIMM is built to match Apple specs and was a great value and made a noticeable difference in daily use of the Mini. Its performance scores in benchmarking apps were already good, but adding this RAM moved its scores up nicely. The Mini is harder to upgrade than a laptop that has an access panel for RAM, but as long as you watch one of the many instructional videos available online, its very manageable. Just be sure to educate yourself before attempting. As far as the RAM goes, great choice and upgrade.

Was able to expand my current new iMacs memory to 40GB - easy install - works great

The RAM is working perfectly with my iMAC. Love it!

Installed the two 16GB cards in the two empty slots of my 2017 iMAC and left the two OEM 4GB cards in the other two slots. The install was easy and it recognized the new memory for a total of 40GB without any problem. A month has now passed with daily use and everything has worked flawlessly.

i5 3.0GHz iMac 19,1 (base model with 1 TB SSD), moved the two 4GB sticks to the empty slots and added this kit to the now-empty slots. Screenshots show 40GB installed and slightly improved transfer throughput (Novabench).
