32GB DDR4 ECC RDIMM for Synology NAS

This 32GB registered DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It uses a 2Rx8 organisation and 288-pin form factor. The memory includes ECC error correction and is validated for Synology RackStation and FlashStation systems.

Suited for Synology NAS expansion needing

Builders requiring unbuffered UDIMM modules or non-ECC memory for consumer motherboards should look elsewhere. The registered design and ECC function make this module incompatible with platforms that do not support registered DIMMs.

Sustained load stability from rigorous stress

Modules are stress tested under load to maintain reliability during continuous NAS operations such as file serving, virtualisation and backup workloads. Registered buffering and ECC correction help preserve data integrity throughout extended duty cycles.

Questions about this item

Does my Synology NAS need registered DIMM slots to accept this 288-pin DDR4 ECC RDIMM?

Yes, this module is a registered RDIMM and requires a system with RDIMM-capable memory slots; Synology RackStation and FlashStation models listed in the compatibility data provide those slots.

Can I add this CL19 2666 MHz stick alongside existing DDR4 2666 ECC RDIMMs of a different capacity?

Mixing capacities is usually possible if all modules share the same DDR4 2666 speed, ECC registered type and 1.20 V voltage; the system will run at the slowest common timing.

How do I confirm the NAS recognises the full 32 GB after installation?

Power on the Synology unit, open DSM, go to Control Panel > Info Center and verify the total memory shows 32 GB with ECC status reported as active.
