Crucial 16GB Single DDR4 2400 MT/s (PC4-19200) DR x8 SODIMM 260-Pin Memory - CT16G4SFD824A

Needed to add more ram to help speed multiple programs running at the same time. Mission accomplished.

it doesnt work for Synology DS920+

I added this to the stock 8GB in my 2017 27 iMac for a total of 40GB. This set is significantly cheaper than the for iMac product Crucial sells. However, the specs are the same and this set works as expected.

The performance change was not worth the cost for the upgrade contacted the seller was only able to upgrade from 8 GB to 16GB for my system but performance lacking

RAM is good...

Good product

Got the Intel 2018 Mac mini as I still need the x86 architecture for work but ultimately saved a ton of cash by opting for the 8gb i5 and performing the memory upgrade myself. While the process was straight forward enough, getting the Mac to recognise the ram was a pain! All came down to the ram not being seated correctly. I was probably a little too gentle when placing the stick in the slots. Total pain to strip the machine down again, and again while performing the upgrade but got there in the end.

Thanks, it really helped! Would definitely buy again.

with pre-installed 8gb

I did a lot of research before this purchase. I wanted a RAM upgrade for a year old Dell Inspiron 7573 laptop. Other RAM manufacturers do a decent job of making RAM for upgrades but Crucial stuck in my mind for a couple of reasons. Their website made it simple to choose the right kit and listed several kits that worked. Secondly, Ive read many rave reviews on their products (mostly gamers reviews).
