Ivan G: TLDR:
It's working perfectly on my Synology DS220+.

Long Story:
I had to clean the memory stick up since it came covered with a bit of grease. This grease defeated my first two attempts to install the memory. The Synology stock on the memory test during the boot, with a blue blinking light. I left it to be for a few hours but nothing. The Synology did not boot. A few days later, I did a last attempt, reviewing the memory stick by itself. I discovered the grease then. It seems that the grease was making connection between two lines of the PCB which was identified by my DS220+ as failure. Fair enough. After the clean job, the Synology DS220+ recognized the memory immediately, booting as normal and showing the new expanded capacity on the Control Panel.

I recommend this memory for the Synology DS220+. It works.

John Flood: After researching Synology NAS I found that their basic RAM is made by Samsung and so the same make should work in the extension slot. The Synology branded RAM was over $100 whereas the Samsung RAM is $30. It worked beautifully. Easy to insert. And DSM recognised it immediately and I now have 6GB of RAM instead of 2GB for a fraction of the cost. I bought Samsung because they make Synology's RAM and that persuaded me over buying the Crucial RAM, not that Crucial don't make good RAM. They do. I worked on the basis that Samsung would be less risky in being recognised by DSM, which I think is the case here.

CSX: I wasn't willing to pay the ridiculous Synology price for the official memory expansion card, so I looked at the specs, and decided that this Samsung 4GB card would meet my needs nicely, while still staying within the official 6GB maximum.

Installation is quite easy: you shutdown and disconnect the box, take out one of the drives (on the side with the memory card slot), carefully insert the new card at a slight angle, then press down gently until it clicks into place with the retaining clips. Then restart, and check the system info to confirm that you have 6GB memory. I experienced no problems throughout this process.

Note: if you do a web search, you'll see various sites discussing the addition of an 8GB or 16GB chip, supposedly this works because the system board supports it. I didn't go there because my system isn't going to be heavily loaded (I use it as a NAS, that's it), so it wasn't worthwhile for me. I seem to have sufficient headroom for all my anticipated needs, and the system performance is more than adequate.

Steve: I wanted to upgrade the memory on my 920+ NAS to better run Docker & a VM. On the basis of another review which said it worked in their machine, I purchased this. (Thankyou Trevor:

I installed it a couple of hours ago and the NAS rebooted without a problem. It is showing the extra RAM, so job done.
