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

Plug and play

Excellent! Work perfectly with my iMac.

Price was reasonable and installation relatively easy. Bottom line is that it worked.

Crucial is the best. They sell high quality RAM at competitive prices and have great customer service. The tools available on their website are great and their RAM is a bit cheaper on Amazon, which is a plus.

Purchased 2 (2X32gb) crucial memory sticks to max out at 128gb memory. After spending two days troubleshooting and inserting/moving/re-inserting the sticks, the Mac wasn’t booting up with (4) crucial 32gb memory sticks. I ended up returning 2X32gb crucial stick and replacing it with 2X32gb Timetec memory sticks. I was able to get all 128gb memory sticks to work at full capacity.

Wasn’t completely sure this Ram would work in my Mac, even given what I had read . It did , however . Also, while DDR 4 isn’t obsolete yet , sodimm is not in high demand , especially for Macs , so getting it was a bit longer than I’d hoped . That said , the seller did the best I could hope for , considering I chose the least expensive shipping option available. I would buy from them again.

Just what we needed.

Easy to install and it was recognized by my iMac immediately. Will definitely recommend.

I installed this memory to a 2019 imac 27in model with Intel i5 3.7 processor. Very easy to install....just make sure you line up the notches correctly when you put them in the slots. I had the base 8gb memory, added 32gb, now my computer is showing 40gb ram total at 2667. Very happy with the purchase and certainly cheaper than Apple prices for ram.
