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

I dont do gaming, so I dont have an opinion about that, but this installed easily and my software for my NAS tells me it is performing as advertised. Synology OEM parts are a bit more expensive, but there dont seem to be any issues with them, whereas some other reviewers found some issues with parts from other providers.

Synology says if you use any memory but theirs your Synology will blow up and no warranty.

Worked perfectly from the outset. I really dont stress my NAS but I wanted to ensure the best performance from the start. Got the Synology extended warranty so wanted to get a factory approved part.

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.

LA MEMORIA RAM DE 4GB, SE NOTA AL INCORPORLA EN LA NAS, FUE FACIL DE INSTALAR Y LOS ARCHIVOS PESADOS NO SE NOTAN AL PASAR DE UNA CARPETA A OTRA O AL VER UN VIDEO O PRESENTACION.

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

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

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.

Synology nas use.

$90 for a 4GB DDR4 ram chip!
