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.

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

$90 for a 4GB DDR4 ram chip!

Good item.

Good, 4 times costlier than Similar product of same quality

Easy to install and works great on my Synology Server

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.

Synology nas use.
