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

I used four 16g sticks of RAM to upgrade my new iMac, after having problems with those from a different vendor. These went in effortlessly and the computer didnt throw any codes. I and the computer are now humming along. The Apple tech told me to get Crucial and nothing else. They seem to know what they are talking about.

Definitely like the increased speed! Seriously thinking about saving up and getting another 32 GB to max out my iMac. Ive never had a problem with Crucial memory.

This has been the quickest install of anything Ive done in my life. Unplug everything, turn the machine upside down, open the memory door, check to see how the RAM modules fit in their slots, put them in, put the door back on, plug everything back in and turn the machine on. Literally less than 5 minutes, with most of that spent clearing the desk and finding a towel to place the machine on. Painless and quick.

Bought a new 27 inch iMac and the memory upgrade direct from Apple was very overpriced. Decided to go with the base memory and upgrade after the after fact with the Crucial memory. This RAM worked seamlessly and was a great value. Been using using Crucial memory for years.

I bought this 32gb kit to replace other faulty ones. It made all the difference in the world.

This item was easy to install and was a great improvement to my iMac. Now, Im running memory of 40 GB 2400mhz DDR4. Much need memory to run some of my Adobe software for my Graphic Design classes.

Imac 27 2020 followed directions in comments for easy install. Works as advertised.

I just returned the OWC 128gb RAM and purchase this one. No kernel panic again. I am so Happy.

Awesome.
