The product seems to be working fine. I haven't run any huge tasks to test it out properly, but my workflow has become smoother once I started using this one.

Great ram that does exactly what it’s supposed to do. You don’t even have to tell it twice!

What can I say about RAM? I can’t watch it spin up, but know it when it doesn’t, if you know what I mean. This 64 Gig RAM upgrade worked great for me. I can now crunch 300 or 400 star trail images or more in a second or less. I couldn’t do it at all before. So, my hat is off to the folks at Crucial Technology and to Adorama for offering the product. I’d take a pic, but those sticks are in the belly of the beast, and I’m not pulling them out.

Installed on my brand new iMac 27 inch. One thing I recommend is pushing the RAM stick firmly down into the port. Works great

This Crucial memory upgrade is fabulous. My iMac is running fast and smooth. I am considering buying another 32gb to max out my computer. Best price available anywhere!

Perfect for what I need it for. Planning on getting another set later on to complete it and make my iMac 64GB

It was literally that simple. Brand new iMac, installed memory before starting first time. System booted right up! Very happy. Just saved a HUGE chunk of $$ by buying the iMac with minimum memory and installing this myself Dont be shy, ,make sure to seat them firmly in their sockets and all will be well! Helpful to watch YouTube installation videos as well.

Worked perfectly. Definitely makes the iMac snappier. Pro tip: it may take around 2-3 minutes for the iMac to scan and 'accept' the memory before it finishes booting up the first time. Just wait it out, and after the first boot, boot times will be the usual super fast.

Great, couldn’t be happier with my purchase and with Adorama, I always receive great service from them. I prefer them over BestBuy or anyone when it comes to my electronics.

I recently purchased a 2017 iMac 27.5 computer and upgraded the memory from 8gb to 40gb with the purchase of 2x16gb sticks from Crucial Technology. Installation was a snap! Adorama recommended Crucial Technology memory and they were great to work with on both purchases and couldn't be happier at this time.

2 - 8 Gb modules along with the stock 2 - 4 Gb modules brings my iMac to 24 Gb of RAM with no issues. Has been up and running for over a week. Saved a bundle over ordering an upgrade from Apple.

Upgraded my 2017 iMac two weeks ago from 8 to 40gb and runs without issue. Doing it's job!

Installed this in my 2017 27" iMac. Like all of the Crucial RAM I have ever used, it worked without issue when I turned the system on. Currently running two sets for a 64GB RAM setup. Note that for most of you, 32GB will be plenty. I wanted extra headroom for some of the photo/audio work that I do for a hobby. Honestly, I probably would have been fine at 32GB after checking my usage while running, but it is nice to have the extra headroom. Items shipped quickly from a drop shipper (directly from Crucial) and Adorama had the best price on this kit when I purchased.
