Synology RS822RP+ DDR4 ECC SODIMM

This NEMIX RAM module adds 8 GB of DDR4 2666 ECC unbuffered memory to a Synology RackStation RS822RP+. It uses a 260-pin SODIMM form factor with 1Rx8 organisation, CL19 latency and 1.20 V operation. The stick is built with major OEM DRAM chips and stress-tested for reliable service in a network-attached storage appliance.

IT teams running a Synology RS822RP+

The module is intended for administrators who want a single validated upgrade for that specific NAS model. It will not suit users of other Synology units, desktop PCs or laptops that require non-ECC SODIMMs, registered DIMMs or a different DDR generation. Builders needing higher capacity per slot or a different pin count should look elsewhere.

8 GB DDR4 2666 ECC SODIMM capacity

The decisive specification is the 8 GB density combined with DDR4 2666 ECC unbuffered signalling in a 260-pin SODIMM. Confirm the NAS has a free slot and that the system firmware accepts this density before ordering.

Questions about this item

Does the package include more than the single 8 GB DDR4 2666 CL19 ECC SODIMM listed in the specifications?

The package contains one 8 GB DDR4 2666 CL19 ECC SODIMM and nothing else.

Should I choose the 1Rx8 rank or a different rank for the Synology RS822RP+?

This module is a 1Rx8 configuration, which matches the specification for the Synology RS822RP+.

Will the 2666 MHz speed run at that frequency once installed in the NAS?

The module is rated DDR4 2666 (PC4-21300) and will operate at that speed when the system supports it.
