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

Wanted my new MiniPC to have 16 GB RAM and utilize the dual channel mode.

Works just fine on PC too, I knew it would. I am just saying this in case some people were questioning if it would. I bought this instead of regular RAM because it surprisingly was cheaper.

Excelente producto, totalmente recomendado

Great RAM. Had no problems what so ever!!!

I upgraded my iMac RAM to 40gb total from the original 8gb purchased. Buying the additional RAM from somewhere other than Apple will save you a boat load of money. I researched that Crucial was one of the better brands to purchase and were compatible with Macs.

Bought a new iMac because my old one gave out. Purchased the standard 8GB from Apple, and bought this RAM rather than pay Apple twice as much. I took out the 8GB and put in the 32GB before I even turned the new Mac on. Absolutely no issues. Mac powered on with no trouble. The reason I took out the 8GB and simply left in the 32GB was because I read several reviewers who ran Geekbench tests on their systems, testing the 32GB (2 by 16) and 40GB (2 by 8 and 2 by 16) and the single core and multi core scores were higher with the 32GB RAM. Its not much of a difference, but I suggest you run some tests on your system to determine which is faster.

Works great with my 5K iMac. No problems

Works perfectly in my iMac 2017, 27 inch, 3.8GHz i5.

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

Installed by the first time in, maybe, 3 minutes. Work like on screen :)
