Perfect upgrade for NAS I bought this to upgrade the RAM in my Synology NAS (DS418play), and it works perfectly. The memory installed easily and was recognised immediately. 5Listed specs can cause confusion, but this is exactly what you need for Late 2015 27-inch iMac I picked up 2 of these x2 kits for my Late 2015 27-inch iMac. I'm happy to report (and confirm for potential iMac buyers) that they work flawlessly. Installation is a breeze, and several guides can be found by doing a quick Google/YouTube/etc. search. The biggest tip I can give is to make sure you avoid static when installing.My iMac properly recognizes these chips, and the specs are exactly what you need. Some of the specs listed don't appear to match up (e.g. 1866 vs. 1867 MT/s) but I can confirm, both from experience and from chatting with Crucial support, that this kit is exactly what you need if you want to upgrade your Late 2015 iMac to either 16GB or 32GB of RAM. 5Works for Synology NAS DS218+ Put it in my Synology NAS DS218+. Works. 5Mac certified RAM, reliable, and at a great price from a company with a good reputation I really don't have much to say, other then I bought two of these kits for my new 27" late 2015 iMac to get a total of 32 GB, and the computer has been rock solid.When I bought this ram it was selling for $109 a kit, and it was too good a deal to pass up to get. a full 32 GB of ram.The memory is extremely easy yo install on the iMac.1. shut down the iMac from the apple menu.2. disconnect all cables.3. lay the iMac face down on a soft and stable surface such as a bed, or other such as a table with a towel over it.4. Use a pointed object such as a pen, to gently , but firmly push the button located inside the power terminal to release the memory door.5 Remove memory door and release the memory cartilage levers.6. insert new modules making sure to line up the notch on the DIMM with the slot and press into place until it clicks.7. lock the memory carriage back into place with the tabs, and replace ram door.8. Reconnect iMac and power one. Don't be alarmed if the Mac takes a few seconds before the chime, as this is normal to test and calculate the new ram, the first time. 5Easy install During Thanksgiving I decided to purchase a new IMac. The only one left with the 27 inch screen was a base model with 8gb ram. As I was using it I noticed the spinning beach ball a few times. Now I'm not a serious programmer that needs a supercomputer to satisfy me, but I tend to have many applications open at one time(photos, I tunes, multiple web pages, and a few apps). This is where ram is probably the most useful. 99% of the time you will never need more than the factory 8gb, but for less than 5 minutes and $100 you can make your machine run a little smoother and a little quicker. Possibly future proof your computer as well being it could last for up to 10 years. I figured I would keep the two 4gb Apple ram chips and just add the Crucial 16gb kit. This is where things got interesting. I read ten different ways that people recommend doing this. I won't rehash all the ten pages of forum discussion just tell you what I did. I placed the new Crucial chips in slots 2 and 4 where the Apple chips were and moved the Apple chips to slots 1 and3. This showed 8-8-4-4 when I rebooted the computer for a total of 24gb. My logic was that the computer would be drawing from the first bank of 16gb before drawing from the Apple 8gb. Either way it works great and took no time or tools to do. If you get the beach ball this is a great upgrade. This will only work with the 27 inch screen and get the right speed for your iMac. Mine was a late 2015 model. 5Not just for Macs... It's not just for Mac systems. I used this in my Synology NAS for RAM expansion, worked like a champ. Crucial has been a reliable brand standard for us for years. No brainer. 4Works with Synology DS218+ Diskstation I used this to upgrade memory on my NAS (Synology DS218+) from 2GB to 6GB - this is also cheaper than the official RAM suggested by Synology. 5New Computer Nightmare Purchased 2 sets to install into a brand new 27" iMac. Before I even turned it on I swapped out the memory it came with (2-4GB) cards for these. I thought it would work without a problem. I fired up the Mac and NOTHING. I was puzzled. I returned the Apple memory and the computer booted normally. I finished setting up up the Mac and shut it down. Again I tried to install the new RAM. Still the computer would not boot up. So I quit.The next day I thought I may have a bad memory card, so I installed one at a time. Each time the computer would boot just fine. I added a second and rebooted. I kept adding/swapping cards until I had all 4 new memory card installed. The computer seems to be happy with the new memory. I'll know more after 24 hours with the new memory "cooking". 4Works great. I added this to my Synology DS918+ to ... Works great. I added this to my Synology DS918+ to give the unit a total of 12gb. Works as advertised! 5Perfect upgrade for a 2015 27" 5K iMac These memory kits are easy to install, and run at the correct speed. Best of all, they're only a fraction of the price that The Fruit wants to charge you for the same upgrade. I installed two of the 16GB kits (a total of four 8GB sticks) and replaced the RAM that my machine shipped with. Took less than five minutes to install, and the iMac is now running perfectly, with memory to spare. 5
