Synology RAM DDR4-2666 Non-ECC SO-DIMM 4GB (D4NESO-2666-4G)

As stated, nothing more to add.

Worked as described in my DS220+. Nice to have the additional memory to run more VMs, containers, and full-text search. Went from the stock, soldered 2 GB to at total of 6 GB. I have a pair of 4 TB HDDs running in RAID 1 on this NAS.

Went with the same brand to ensure support for the Synology nas and memory card.

The extra Ram might speed up your NAS for certain tasks, like video recording.

It works, I now have 4 more GB of RAM in the NAS.

$90 for a 4GB DDR4 ram chip!

Synology nas use.

update: dec’21:

This Synology ram has the same specs as the Micron MTA4ATF51264HZ-2G6E1 which you can get on Amazon for $10-$20 but Synology slapped their name on it and their charging $90 for it. If you want to save some money get the Micron MTA4ATF51264HZ-2G6E1 instead. Ive seen Youtubers using the Micron ram on their DS920+ without any issues.

Easy to install and works great on my Synology Server
