Review: 72 GB RAM at 2667 Mhz in 3GHz 2019 iMac19,1 with addition of 2 x 32 GB kit - CT2K32G48FD8266 - This Crucial 64GB Kit (2X32GB) DDR4 2666 MT/s CL19 SODIMM 260-Pin Memory - CT2K32G4SFD8266 - works with the 2 each 4 GB 1Rx16 (single rank) SK Hynix RAM modules (each Part Number: HMA851S6CJR6N-VK) supplied by Apple in my 2019 iMac 27 inch 3 GHz 6-Core Intel Core i5 system purchased from Apple in January 2020. The desertcart description notes that the 2 each 32 GB Crucial (Micron) RAM modules (each Part Number: 16ATF4G64HZ-2G6B2) are supposed to be "Single Rank", but they are clearly marked as "2Rx8" (dual rank) on the attached label. Utilizing existing 2 x 4 GB modules, 72 GB RAM total (all running at 2667 MHz) was installed in the following configuration (Bank 0 at bottom of cavity) in about 15 minutes: BANK 0/Channel A-DIMM0 32 GB Crucial, BANK 1/Channel A-DIMM1 4 GB SK Hynix, BANK 2/Channel B-DIMM0 32 GB Crucial, BANK 3/Channel B-DIMM1 4 GB SK Hynix. The initial system boot after RAM installation took at least 30 seconds longer than usual, but subsequent boots have been quick. Despite not being Single Rank modules as advertised, I'm happy that I'm able to use this kit with my existing Apple provided RAM at full speed. Thanks to 'darcy' for writing your review on January 1st, 2020, at desertcart.ca to confirm that this kit worked with this system! Your review was the only one anywhere across the Internet confirming this Crucial 2 x 32 GB kit in a 27 inch 2019 iMac. Hopefully the model numbers in this review are useful data points for future Crucial, desertcart, and Apple customers. Thanks for quickly delivering a quality product at a reasonable price.
Review: Great quality and desperately needed memory upgrade. - Wow, what a difference. My Dell XPS 15 was getting really sluggish. It had 16GB of ram but I was sitting at 85% or higher of memory usage. Did some research and found that the max memory I can have is 64GB so I bought this kit and my PC is WAY more snappy and responsive. Now even when I start pushing the limits with Msft Teams, Outlook, several webpages, Powerpoint and more running, it gets up to about 30% memory usage. I have not tried editing videos yet but I suspect that will work smoothly given it's snappy with all the other memory hogging applications that I've run simultaneously. I've worked in the tech space for years (including at a major CPU company) and know Crucial is a great quality memory supplier. While researching kits, I saw a LOT of no name brand solutions but knowing how important memory is in the stable operation of a PC, I didn't want to trust my system to low grade memory chips. Overall, very happy with this memory kit...it's made a big difference in performance on my laptop.

### ⭐⭐⭐⭐⭐ Works great in my iMac
*by G***N on September 26, 2021*

Installed perfectly in my 2019 iMac 27" 5K unit. Went from 8GB as received to 72GB in a matter of minutes. No issues at all after more than 18 months of heavy use in a developer machine -- simulators, in-circuit emulators, virtual machines, etc. Way cheaper than buying Apple memory. Crucial uses Micron chips, same as Apple.
