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

Work exactly as expected for my iMac 27 model from 2017.

Memory upgrade for my 27 inch iMac. No more spinning color wheels! Easy to install following online instructions, foolproof slot prevents incorrect placement in the computer. Well packaged.

The RAMM arrived the next day and it worked perfectly. I have bought from this company several times before and they are very reliable. I have an iMac and it was installed in less than 5 minutes. Great products!

I bought Crucial 32GB Kit (16GBx2) DDR4 2666 for my iMac Retina 5K 2019, removed original ram and placed 3 sticks. first thing what I mentioned boot speed slowed down, I tried to replace to another slots but result is the same.

If youre wondering, yes, these can be added to the factory sticks that your machine came with - in my case adding these 32x2 gave me a total of 80GB and made a real difference.

I bought this 16Gb Kit Single Rank for my 2017 iMac 27-inch (Model No. A1419/ MNED2RU/A). Installation took just two minutes! I just inserted the new memory into two available slots. Didnt even see that black ini

Reasonably priced upgrade for MAC memory.

I bought 2 sets of this ram for my iMac. 1 set worked great and the other didnt work at all with my iMac. The number CT2K32G4S266M on the package did not match that number on the cards included in that package. How that happens is beyond me but I have a refund and will try again to get the correct cards. When the product is the right thing they are great.

What a dream. Instantly improved the speed of my 2017 iMac 3.4 GHz. I will buy another set in the future.

I put 64 RAMs in my base Imac desktop and it worked perfectly
