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

Decided to go with the pricier memory from Synology because I decided the cost savings by choosing another memory chip brand wasnt worth it. I just want something that works perfectly.

It works as expected. Easy installation. Follow ESD installation guidelines.

Four stars because of price, but other than that I have had no issues when using with DS220+. Rock solid

As stated, nothing more to add.

Only purchased to maintain my 920+ warranty even though any other 4gb stick would work fine. Should be 50% of its current cost ($100~).

No issues whatsoever. Installed in a Synology DS920+

$90 for a 4GB DDR4 ram chip!

And simple to install.

It is designed for the synology, I went with brand recommended

It does what it is supposed to do. Just a bit expensive due to its Synology branding and certification. Other brands of this spec likely would have worked just as well for a lower cost.
