Un seul regret: la compagnie n'a pas prévu plus que 2+4 Go




I'm running a DS218+ and installation was incredibly simple. I just had to shut down the NAS, pull out my drives to access the expansion slot, push in the module, lock it down, put my drives back in (make sure you put them back in the same drive bays they came out of), boot it back up and the RAM was recognized.
Make sure you need to upgrade the RAM before doing such. If you're using your Synology as basic network storage then you probably don't need to upgrade. In my case I'm using it for network storage, source control, a media server, and more, so I was capping out on my RAM frequently. Post-installation I did notice quite a bit more breathing room which is nice.
People seem to have great success with Crucial RAM so if you're running a personal NAS then I'd definitely go that route. If it's for business then maybe consider going with officially supported RAM but also you'll probably be just fine with something like Crucial. I happen to be hyper-paranoid so I went official. It's about 3X the cost and honestly it's not really worth the added cost, but at least there's a slight peace of mind knowing the RAM I'm using is official, but that peace of mind comes at a ridiculous cost so for most people it's probably not really worth it.

The culprit? Non-Synology RAM. Trying to save a few bucks, I had purchased two Crucial 8GB SODIMM modules for use in the NAS. The memory tests revealed tons of memory-related issues. After replacing the two non-OEM RAM modules with the single one that came with the unit and rerunning the memory test three times, no errors were found.
So, lesson learned. Is this Synology memory expensive? Yes. But, you get what you pay for. My trying to save a few bucks cost me several days of anxiety and several hours running memory tests and sitting in on the SSH session which LUCKILY restored my data.
Also, the use of non-Synology RAM modules is NOT supported. The Synology tech was nice enough to help me out despite that. And, you void the NAS warranty if non-Synology RAM causes damage to the NAS motherboard, RAM slots, etc.



Initially I purchased a Crucial 16GB (2 x 8GB) DDR3L kit to upgrade the DS918+ (following several guides online) but within a few hours the NAS shutdown and restarted unexpectedly and rebooted itself again a few hours later. Unfortunately 3rd party memory kits are not supported at all by Synology and they only recommend 8GB (2 x 4GB) of their RAM on the DS918+. Random reboots risk losing data so I gave up and put the original RAM back in.
I decided to bite the bullet and buy the additional 4G of Synology D3NS1866L-4G RAM. The RAM is very well presented and not only comes in the regular plastic shell but also a Synology branded box. I installed the module alongside the original in my DS918+ a few days back and it's been running perfectly since (no random shutdowns etc.). Unfortunately you are paying a massive premium for this RAM and the single 4GB stick is nearly as much as a 16GB Crucial kit but it works perfectly and Synology will honour the waranty etc.
Pros:
- Works perfectly in DS918+
- Easy to fit
- Well presented
Cons:
- Really expensive


I made that mistake and paid for it!
When they tell you 8GB of ram is the Max,
It’s true!
I put 16 GB of a different manufacturer in and had nothing but trouble,
None of the packages would work correctly
Docker would not run, constant ram leak which would then freeze up the NAS and only a hard reset could sort it.
Took me a month of playing with settings assuming it was a software setting problem before I put the original ram stick back in and everything works like a charm!

There is a downside, this is very expensive for 4GB of RAM, also I cannot see how these are made for each other! The RAM module has to be balanced in the slot and held by friction, as there is no way it clips into the side slots, as I would expect laptop RAM to be fitted. Time will tell if they work together well over the long-term.


Having checked around afterwards there were several other cards of similar size and spec from other well established brands at virtually half the price so it looks like Synology are trying to milk/blackmail the customer in exchange for their warranty. Not great, but the card itself was easy to install, was recognised straight away (it’s plug n’ play) and worked perfectly.




Can connect to it from anywhere in the world and see your files, play your music Videos etc. Easy to connect up to All home devices, Phones Laptops TV etc..
Synology has some great apps. Clouds are OK but if you want more security, then this is the answer.
