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

It meets all my expectations!!!

exactly what I needed for my iMac, great price

Las memorias llegaron a tiempo y en buena condición, las instalé en mi iMac 2020 y funcionan a la perfección.

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

Installed 32GB into my 2017 27-inch iMac and it seems to be working fine with the two 4GB modules that came with the computer. However, when I ordered and installed another 32GB the computer started crashing every two minutes. I tried to install the two new 16GB modules again but it didnt get any better. I removed the two 16GB modules and put the original two 4GB modules back into the computer and now its working again. Im sending the 32GB kit back to Amazon. I wish I had 64GB of memory but will have to do with 40GB.

Added this to the 16MB on my iMac 27 2017. Works perfectly.

EASY install, RAM popped right in and was immediately recognized. My computer is handling Logic and Final Cut with ease now. No rainbow wheel of death! The price was a bit high, but I needed the upgrade and couldnt wait.

Timely delivery for update to the 2017 I5 27 inch Imac. Works great and is easy to install. Make sure you add it in pairs to ensure optimum performance.

Installed on late 2017 27 iMac 5K. I had two OEM 8GB cards installed already by Apple. The key is to leave the factory ram cards exactly where they are installed by Apple. Then take the two new 8gGB Crucial cards, and firmly install them in the two empty slots. Close the little door, and plug it back in. My iMac booted up in under a minute and recognized the new ram immediately. I now have 32gigs of ram, boom.

Mac mini late 2018 is a nightmare to work on but thats not Crucials fault.
