NEMIX RAM 8GB DDR4 2666 ECC SODIMM Synology RS822+ memory upgrade

Synology RS822+ DDR4 ECC SODIMM

This 8 GB DDR4 2666 ECC SODIMM is built for the Synology RackStation RS822+ NAS. It targets administrators who need to expand memory capacity in that specific rack-mounted system. The module is unbuffered and operates at 1.20 V. It is not suited for desktops or laptops that require non-ECC memory.

2666 MT/s CL19 single-rank specification

The decisive specification is the DDR4 2666 (PC4-21300) speed with CL19 latency in a 1Rx8 organisation. This exact combination matches the RS822+ memory controller requirements. A different speed, latency or rank configuration would prevent the NAS from booting or cause instability. The 260-pin form factor ensures physical compatibility with the system's SODIMM slots.

Single module enables incremental upgrades

The package contains one 8 GB stick, allowing you to add capacity in 8 GB steps up to the platform limit. No heat spreader is included, which keeps the module height low for dense rack environments. There is no bundled software; the upgrade takes effect once the module is seated and the NAS is powered on.
