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

Prices will drop but its great for now! Originally swapped out the 8gb from a Mac Mini 2018. Works flawless and without a hitch. Constantly at around 36+ gb of use so I know it will pay itself over.

Awesome.

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.

As always, Crucial is the best all around brand for Apples (upgradable) computers. Crucial is owned by Micron, a company that Apple themselves uses as an OEM supplier. If youve ever pulled RAM out of a Mac before, you might have seen Micron on the labels. Crucial supplies their own branded components that youd never see inside as OEM on a Mac, but the RAM itself is Micron underneath the Crucial label. Its the brand I always trust most with RAM upgrades on a Mac. Its not the cheapest, and is far from the most expensive. But it is the most dependable. And trust me, you want dependability if youre going to go through the hassle of upgrading the memory on a 2019 iMac.

This ram has high reviews. I ordered, received, and quickly realized this is DR 3, not DDR 4. The package was labeled DDR 4 from Crucial. However, the little locating slot was in the wrong spot. I could not seat the chipset. I compared to the DDR 4 and that is how I realized this was actually DDR 3 and it was not going to seat.

Been using Crucial RAM chips for years in my iMacs. Theyve never failed for me unlike the other no-name brands Apple puts in their machines which has caused me grief to say the least. Crucial is a quality brand name you can count on at a decent price. My Mac era usage goes way back to Si, Ci, Power PCs, etc. Love my Macs, but like dependable memory in them!

Works perfect in my 2019 27 iMac Do not pay for RAM at Apple!
