Synology DDR4 2666 ECC SODIMM

This 16 GB DDR4 2666 module brings ECC protection to compatible Synology NAS units. It runs at 1.2 V with CL19 timing and uses a 260-pin unbuffered SODIMM form factor. Major OEM chips from Samsung, Micron or Hynix are tested under load before shipping.

NAS owners needing single-slot 16 GB ECC

The single-rank 2Rx8 design fits one slot, so systems with only one free socket can reach 16 GB without pairing modules. Builders who need higher total capacity or registered DIMM support should look at something else, as this kit provides only one unbuffered stick.

No extra accessories or software included

The package contains only the memory module itself. There are no heat spreaders, tools or configuration utilities to install. Compatibility is validated for the listed Synology platforms, so the module works immediately after seating it in the slot.

Questions about this item

Which Synology NAS models accept this 16GB DDR4 2666 ECC SODIMM?

This module is designed for Synology systems that support DDR4 2666 ECC unbuffered SODIMMs; check your NAS manual for the exact model list.

Can I add this 2Rx8 CL19 stick to a slot that already holds a 1Rx8 DDR4 2666 module?

Mixing ranks is often possible but the system will run both sticks at the lowest common speed and latency; verify with the NAS vendor.

How do I confirm the 16GB 2666 ECC module is recognised after installation?

Power on the NAS, open the web interface and view the memory section in System Information to see the new 16GB capacity and ECC status.
