DDR4 ECC SODIMM for Synology NAS

This 8 GB DDR4 ECC unbuffered SODIMM is a memory accessory designed to expand the RAM in compatible Synology desktop NAS units. It adds capacity for multitasking, virtual machines and heavy file-service workloads. The module uses error-correcting code to protect data integrity in always-on environments.

Fits 22-series DS3622xs+ and DS2422+ only

The upgrade is validated for the DS3622xs+ and DS2422+ models in the 22 series. Owners of other Synology NAS models or non-Synology systems should verify compatibility before purchasing, as this module is not qualified for those platforms.

DDR4 ECC unbuffered SODIMM specification

The single decisive specification is the DDR4 ECC unbuffered SODIMM form factor. Only NAS units that accept this exact memory type can use the module; any system requiring a different generation, registered DIMMs or non-ECC memory will not be compatible.
