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

Took two tries to install. I didn’t properly seat one of the Crucial modules the first time. Reinserted them again with a little more force the second time and the computer restarted perfectly with all RAM modules functioning properly.

Worked good registered on computer just fine.

My wifes HP laptop had 4gb of memory but only one memory slot. It was very slow booting and almost as slow waking up. After installing the 8gb memory the laptop is dramatically improved. I suppose this review is less about the memory and more about HP building such a slow laptop that is easily made faster.

My review is for: Crucial 32GB Kit (16GBx2) DDR4 2666 MT/s (PC4-21300) CL19 DR x8 SODIMM 260-Pin for Mac - CT2K16G4S266M

Easy to install and greatly sped up my 2017 27 iMac. It originally had 8gb, and I added this 16gb bringing the total to 24gb. Installation was very simple - I had it installed and running w/in 15 minutes of it arriving at my door. Id recommend as its much cheaper than getting from Apple, and the install is very simple. Works perfectly.

exactly what I needed for my iMac, great price

Basically, bought this memory to go inside my 2017 iMac 21.5. Was a bit tough going thru the disassembly but in the end, I now have 32gb of crucial memory.

Excelente producto, totalmente recomendado

Received these straight away after returning the Corsair. These passed the built in diagnostics in my iMac, and so far I havent had any issues with crashing. About this Mac is showing 40GB as I have 8GB of stock Apple RAM. Ive installed the RAM as follows:

Great value and easy to install
