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

Most like: easy installation. Recognized immediately. Brand reputation. Least like: increasing cost of memory

works like a charm. my Laptop is now supercharged and really fast together with the SSD!

I bought this for my 2017 iMac and it works beautifully.

excellent product at a good price, bought it for my new iMac.

I bought 2 kits for a total of 64GB. Installation was easy and my iMac immediately detected all 4 DIMMs. I havent had any problems. Saved a lot of money getting the RAM this way than getting it with the iMac from apple.

Great alternative to apple’s horrible price for ram upgrade

Worked great on 2017 imac

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).

I purchased an iMac beginning of 2018 waited a while for the price of ram to come down and purchase the 32 gig kit installed it in my iMac for a total of 40 GB. Very easy to install works great no problems

Works Great
