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

I installed this memory to a 2019 imac 27in model with Intel i5 3.7 processor. Very easy to install....just make sure you line up the notches correctly when you put them in the slots. I had the base 8gb memory, added 32gb, now my computer is showing 40gb ram total at 2667. Very happy with the purchase and certainly cheaper than Apple prices for ram.

I searched on memory a 27 2017 iMac and this came up first in my search. These did not fit in my iMac. I pulled out the original memory modules that came with the computer and these were larger.

Works perfect in new iMac at a fraction of the price. Im shocked Apple still allows this. Ive been using Crucial for years and their stuff is great.

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

Perfect for the task, but the packaging could be more robust.

Great alternative to apple’s horrible price for ram upgrade

Good price, fast delivery, super easy installation, happy 40 GB iMac, very happy owner/user.

Ordered and installed 16MB IN Works great in the 2017 27 i7/8GB GPU iMac. Easy install and worked great for a total of 24MB Memory.

Working great! Installed on an iMac 27” mid 2017 with i7 and 8GB video card.

great performance!
