3rd party RAM memory for NAS DS225+

[Enquiries]

Hello,

I just bought a NAS Synology DS225+ (with 2GB RAM) and I read that you need 6GB RAM to use the face recognition in Synology Photo.
The Synology 4GB RAM is extremely expensive 166,60 €

Therefor I consider buying 4GB 3rd party RAM, but I am not sure which one to buy. I found this one from Amazon, but it is 2400Mhz and I think it must be 2666Mhz. I have no idea how important this is 2400 or 2666Mhz.

If you can advise me which is a good brand or better to buy the very expensive Synology RAM.

Thanks in advance,
Guy

The good news is that the DS225 Plus is not strict about RAM in the same way the older DS220 Plus or DS920 Plus were. Synology still recommends their official module, but third party RAM works fine as long as it’s the correct type.

Your NAS needs DDR4, 2666MHz, 260 pin SODIMM, non ECC, unbuffered.
It will also happily downclock faster sticks, so buying 2666MHz or 3200MHz is perfectly fine.
The module you found (2400MHz) usually also works, but it’s older and not ideal when 2666/3200 are the same price.

The most stable 4GB third party modules people use in the DS225 Plus are:

Crucial 4GB DDR4 2666 SODIMM (CT4G4SFS8266)

Kingston 4GB DDR4 2666 SODIMM (KVR26S19S6/4)
https://www.amazon.com/s?k=Kingston+4GB+...=ncmail-20

Both are reliable, inexpensive, and widely used in Synology models without issues.

Synology Photos face recognition will run perfectly with 6GB total RAM, and you don’t need to spend 166€ on the official module unless you want full warranty purity.
