I bought the cheapest 4 gig RAM upgrade I found on Amazon for my DS-218+, and am happy to report that it works perfectly. In addition to the normal NAS functions, I'm using docker to host a dot net core app and the additional RAM is a big improvement. The specs are: NEMIX RAM 4GB DDR3L-1866 Memory PC3-14900 SODIMM -- fyi, I don't work for this company.

The safest way is to go to Crucial Memory for Mac if you want to avoid trial and error. It's nice that the one you picked works !
I added 8 GB of Crucial memory for mac to my 4GB DS918+ and it works like a charm !
Brand has nothing to do with that. what you need to do is go to the intel spec page for the CPU and buy memory with specs that match what CPU supports. That's it. Brand is irrelevant.
Brand is irrelevant.
Yet, I prefer to buy it from a big player (Crucial, in my case), with a proven track record. Especially NAS usage, where you want/need data integrity.
Cheap products (ram in this case) are cheap for a reason. I just wouldn't risk it to save some bucks.

You are making an excellent point - but in this case you should buy ECC memory. Any memory from any brand can fail, and pretty much any DDR3/4 memory is susceptible to rowhammer. So if data integrity is at stake - buying from known brands will not save you.

This is true for many products, not just for memory, and yet, it is irrelevant. Yes, they may be using lowest binned parts but that does not matter at all. This is all noise.
In reality - if you care about data integrity you should not even consider getting non-ecc memory.
If you did get non-ecc memory then data integrity apparently was not important for you so might as well save up some cash. Note, nothing wrong with that - some buy synology units to use as media centers, some buy to store family pictures. two drastically different set of requirements for reliability and integrity. For media center I'd go with RAID0 and would not worry about it rebooting twice a day really.
And that said - there price difference in ram stick is mostly marketing. They use chips made by the same big players, (albeit graymarket) but eventually if the stick passes the tests -- it works. I don't bother with name brands. Sort by price, pick the first. Sometimes it happens to be Crucial/Micron/Hynix/Kingston, sometimes its some Chinese no-name. Over years I did not notice any significant difference (or any) in failure rate.

Doesn't this only really apply if ALL of your devices have ECC memory? If my data lives on the NAS with ECC but all of my endpoints have garbage RAM, any one of those endpoints could botch the data, no?
Also, doesn't BTRFS prevent data corruption?
Nice one. Someone willing to take the plunge.
I've thought of this, but as I have a 412+, it's not going to get any feature updates, only security updates going forward. I'm not certain that it's worth investing too heavily into an essentially outdated product. How much did that stick run you? Mine runs well enough for now, and RAM is probably what I would need most/first so it's not out of the question. I've got docker set up and am slowly adding more and more stuff to it, so that may change at some point.

Oh, ok that's not too bad. Figured it'd be at least 2-3x that much. What do I know?
I upgraded to 16gb ddr3-1600 and it's working great. I'm also thinking that 16gb was overkill for my automated media center/downloader. I get, maybe 5gb max utilization, even transcoding and multiple streams going at once.
I'm planning on putting up a simple web server, so that might push it up a bit.
I dropped 16 in my Ds2415+ and its been working great for 2 years
I also have the 218 with about 8tbs of data. I don’t think I need more Ram, I’ll do it anyway just for shits and giggles. I guess I’ll order some.
Anything to do other then plug and play?
Shut it off first. It'll boot right in to it and you can check the resource monitor and whatnot and confirm right away that it's working
Is there any point in running some kind of RAM check? I dont Remember the namn of that program you load up on usb and boot in to. Ramtest? Then run for several hours.. Im asking cus i recently bought a 8gb ddr4 none ecc in 2nd hand couple months ago. Everything seems to work fine but ive been thinking of really testning it properly.
Ecc memory is sadly not an option for me..
Curious whether adding more RAM to a NAS with very low RAM utilisation and no swap usage (1517+) is expected to yield any benefits performance wise?
I put 16GB in my 1517+ and 32GB in my 1618+.
¯\_(ツ)_/¯
And did it have any impact on performance?
Dunno, because I upgraded both before I turned them on. But I haven’t had any performance issues with either NAS and both run with a comfortable overhead.
It will cache data in the unused RAM, so you should see some sort of performance benefit there, but I haven't seen any tests to indicate just what sort of benefits you'll see.
I have 8GB in my DS418Play. I usually see about 500MB utilization, and ~6GB of cached data.
That's the one.
Save original ram otherwise they will not support you.
Eh, not entirely true seeing if you have to RMA it, they will tell you to pull all the RAM out anyways before sending it in for repairs.
I think they usually prefer you do not open the unit before sending it back. They just ask that you remove the drives.
What are you talking about? RAM is user serviceable on that unit.
Ah. I was unaware.
For RMA, yes. But if your system crashes or becomes unstable (due to 3rd party RAM) it could be a part of the troubleshooting process and they may not be able to help if you don't have the original module for reference testing in this process.
This is simply not true. If memory is right spec and passes memory test they will support you.
From past experiences they would not support me unless I had stock ram in my device. May have just been the individual I was working with
Could be. They recently ( within last year I think) restructured support and apparently hired a bunch of new people and for a while support quality went down. But then it returned back to normal (And I happen to use their support a lot, mostly due to hardware/software issues that I keep stumbling upon due to not exactly common use cases). Not even once they brought up the fact that I have non-synology memory; all they ever asked was whether I ran memory test, and then went straight to triaging issues..
Edit: and it would be crazy to do anything else -- memory spec is defined by CPU vendor, not Synology, and Synology do not make memory, they slap their sticker on ADATA parts. So they have zero say on interaction between CPU and RAM. As long as it is within specs that CPU can support and passes memtest it's all good.
