DS923+ 8GB (non-official) ECC RAM recommendation

Hi everyone,

So, I have a DS923+ with the stock 4GB of RAM and while it is running fine most of the time with my Docker containers, I guess everything could be more fluid (e.g. scrolling on Jellyfin while it is loading info / images, video buffering if moving forward / backwards, etc). Since the Linux OS uses free RAM as cache, I was looking to buy an extra stick of RAM. I was thinking of buying a 8GB of RAM which in total my system would then have 12 GB. Not sure if overkill, but still, I run a few containers.

I’ve actually searched on the Synology subreddit, but everyone is basically buying 16GB of RAM or maxing out the GB allowed for the RAM on the DS923+. So, that is the reason why I’m asking here.

I know that Kingston has some 8GB RAM sticks which should work with DS923+ but it seems they are blacklisted by Synology, so it seems you will always have a warning on the notification list which I wanted to avoid. :/ But on that list (see here: Ram list), it seems the 8GB RAM that Synology uses is sourced from Innodisk or Adata, so one shouldn’t get any warning there. Sadly, I can’t find them anywhere for sale. Even when I contacted the companies directly.

In conclusion, has anyone bought a 8GB ECC RAM for the DS923+ which doesn’t give a DSM warning?

Thanks everyone in advance! Cheers!

I have installed 2x16GB Kingston KSM26SED8/16HD modules in my DS923+.
I initially wanted just 1x16GB but it was in a quite good offer at the time I was interested in, so I decided to buy 2 of them.

The same specs are listed for 8GB module too (KSM26SES8/8HD) on Kingston's site, but I believe the price difference is not much. Just add the 16GB, tested working.

These modules are listed as compatible with the DS1621+ but it has the same RAM specs with DS923+.

The message is just a warning, no further issues. The memory modules were tested by Synology Assistant memory test and no problems found.
I disabled this memory incompatibility notification with this script.

Thanks for the reply!

Yeah, it seems that only 8GB ECC RAM that is available for sale to consumers seems to be the Kingston. I haven't found anything else.

Nevertheless, if someone reading this is interested on larger GB, if you actually to upgrade to 16 GB or 32 there seems to be RAM available by TimeTec or Innodisk for sale which don't give any warnings (you would need to search on Reddit for Synology RAM Megathread), but sadly for 8GB I can only find this Kingston which provides a warning on the notification list.

But thanks for the link to the script! I think that should be the way to go for me.

Cheers!

The warning message is nothing that you should be concerned of. It is just an annoying notification that you see once on every boot. Just clear it.
Synology lists only their branded modules in the compatibility list. So, in terms of support, every other branded module either triggers or not this warning, is out of question for Synology when you need their help.

I would suggest to search for a module that has the correct specs and forget about the compatibility warning.

Could it be some NAS’s do not report 3rd party RAM?
I’ve used Crucial 4GB & TimeTec 8GB RAM in 720+, and was never prompted about RAM, but was Prompted about Barracuda spinning drives and TimeTec SSD’s in the same 720+

Final note: using non-supported SSD’s (TimeTec & Micron) in external eSATA enclosures on multiple 720+ & 718+ NAS’s: connected to external eSATA busses….. and nary a peep from Synology! But same drives internally prompt as non-supported!

I don't know what is the mechanism or the criteria that Synology uses to check compatibility.
I suspect it can happen that 3rd party ram module characteristics are exactly the same that Synology's modules use and may be part of this detection mechanism, so finally reported as compatible.
For hd drives I understand that it is a matter of adding them to the supported db, this is what the above script does.

The only time I’ve seen the drive nag on 720+ is when I first install them. After that, it’s quiet. Never have seen RAM nags on 720+, and seeing that I see RAM NAG posts, just assumed some NAS do/do not Nag???? I do have Active Insight Off, though.

Ah, good to know that you can just clear the message! I thought it stayed "fixed" there for forever. Then I guess it does not matter much. Thanks!

I just have one extra question. Kingston has two different versions of the same RAM. It seems the difference is simply the chip's brand: one is Micron and another is SK Hynix. I know that Micron is usually considered "better" but, does it matter for the NAS? I simply ask because where I live the SK Hynix is around 20 bucks and the Micron version is around 50 bucks, so basically double the price. Not sure which one should I choose.

It's just Synology being a pain in the butt to scare people so that they buy the official Synology parts for 3 times the price. I wouldn't mind that price if it was actually manufactured by them, but no. They simply order the cheapeast RAM they get around the corner and slap the Synology sticker in there. That to me is a bit "unethical / low" from their part but okay.
