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

Perfect for my iMAC MNED2LL/A. Easy as 1,2 and 3. No issues. I installed the memory and it booted right up. I didnt have to rearrange the pre-installed memory or anything. I installed them and they worked! Awesome! Good price too.

For as long as we will be able to upgrade our Mac computers, this is the BEST.

Solid memory. Does not crash

Perfect upgrade for my 8gb RAM laptop. Works as advertised

Thank you for making and selling these!! Our basic but expensive Mac was getting laggy when working on large photoshop or Adobe files. We didn’t want to pay $400+ plus for an apple RAM card and we’re so happy when we found these.

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.

Easy install.

worked perfect on 2017 27 iMac

Install was super easy, took maybe 2 minutes. I got 16gb (two 8 gb). Just unplugged my iMac, opened the back panel that holds the RAM, I took out the RAM that was already in there and replaced those slots with the two 8 gb and put the other two that came with the iMac in the remaining slots. Put the panel back on, plugged it back in and started right up.

These memory modules worked perfectly in my 2020 27 Mac. Installed easily in slots 1 and 2. I did not try to utilize my existing 8GB of RAM but 32GB total should be enough. I opened several applications and it showed I was using 17GB of memory. No wonder it had problems with just 8GB of memory.
