I have a DS920+ which I haven’t upgraded the ram for, so it still has the default 4GB on it. Reading around, it sounds like Synology only supports adding an additional 4GB for it, but some other sites mention putting an additional 8 or 16 into it.
Has anyone upgraded theirs with more ram? What have you added and what were your experiences?
I added 16GB to mine. It was recognized without me doing anything special. I run about 15 Docker containers in addition to the normal Synology suite. I only end up using about 3 GB of ram, but I don’t mind having 17 GB available for paging.
I’ve just added 8GB on a DS416Play and it sees all of it.
Edit: Oh and going from 1GB, general performance is night and day. No more swap grinding down performance and I’ve disabled memory compression.
I added another 32GB to my 923+ recently. Looking around, I found that speicher.de (German shop specializing in RAM) offers RAM for specific Diskstation models beyond Synology’s specification, and they guarantee you that it’s going to be working! (They call this “overRAMing”). For the DS920+, you can find the offered RAM sizes here. I have had zero problems, my NAS now has 36 GB RAM, shows no errors or warnings, and I’ll probably upgrade it to overall 64 GB sometime. And my 218+ runs with 10 GB RAM since several years without any issues or warnings. Rather the opposite: in both cases, the difference was tremendous, it felt like entirely new (much faster) devices. I can highly recommend.
[Edit: I changed the German links to the corresponding ones of their English site]
I was able to add 16gb to my ds220+ for a total of 18gb, which exceeds what Synology claims you can run. Had success with timetec, but have heard crucial works as well.
Main thing that was an issue for me was having to reinstall the ram a few times. Don’t be afraid to be a little rougher than on other machines, needs to be fully inserted and it took a good bit of force for it to finally take
