Quick delivery and great price from B&H. Memory modules fit correctly in early-2018 iMac, instantly recognized by High Sierra. Excellent way to upgrade memory in an iMac without paying the higher Apple price.

I’ve only had the memory upgrade for a week, but no issues. I had 16GB of memory on my 27 iMac (2017). I didn’t notice a speed increase until after I launched all my apps the first time. I have quit those apps, and the launch speed has increased. Processing in Photoshop, InDesign and Illustrator are faster, but not as fast as your machine is without tons of fonts and programs, like I have. If I deinstalled all the fonts I never use, I would see a little more increase in speed.

I bought this to increase the memory in my Synology DS1819+ from the standard 4GB of RAM to the listed max of 32GB of RAM. Everything is working well!

Installs easily and immediately recognized by the computer. Much better price than the OEM Apple memory. If you are keeping your original RAM for your iMac: the Slots (from the top) in the #2 and #4 position are the “primary” slots for the computer. You can mix and match pairs of memory, but from the research I found it was best to keep the pairs balanced. So when you install the larger memory, and if you have open slots — put the original iMac memory in slots #1 and #3, and move your new (larger) memory pair to slots #2 and #4. Good luck!

I bought two of these, to upgrade the memory of my new iMac from 16 to 32 gigs. They were a snap (literally) to install, worked right away, and have been fine for more than two weeks now.

My IMac runs now so fast after installing the additional memory. I had a little problem early on but the tech support folks at B & H were there to consult with.. all is well. Thanks Dr. Gibran Majdalany

After 3 weeks my 2017 iMAC would not start with this item installed AND with(2) Apple provided 4 GB RAM modules installed. Computer did start with EITHER the Apple or the Crucial memory installed separately. Crucial replaced their memory and new memory now works with Apple memory. However, I note that the picture of the module shown here has a blue and white label. The modules I received from B and H had an all white label. The replacement labels from Crucible has the blue and white labels. I do not know if that means anything. Label numbers are the same.

They work as expected. I don’t have any reason to dislike them, but I am not blown away by the speed. They are just fine.

Added 32GB to my existing 16GB on my 2017 iMac 27 inch. Did a speed test using GeekBench software. Only a minuscule improvement in CPU speed after tripling the memory of the computer. NOT worth the money. Two stars because they work with my computer. Delivery took almost 10 days to get to California.
