Synology DS3622xs+ ECC SODIMM

This 16 GB DDR4 2666 module is built specifically for the Synology DiskStation DS3622xs+. It adds ECC unbuffered memory to a NAS that relies on data integrity for file services and virtualization workloads.

Capacity and headroom

The single 16 GB stick raises total memory in 16 GB increments up to the platform limit. ECC protection covers single-bit errors during sustained workloads. The module runs out of headroom when the NAS reaches its maximum supported capacity or when applications demand bandwidth beyond DDR4 2666.

260-pin unbuffered layout

Samsung, Micron or Hynix chips operate at 1.2 V without a heat spreader, keeping the form factor slim for the DS3622xs+ SODIMM slots. CL19 latency at 2666 MT/s matches the system memory controller. The 2Rx8 organization fits the platform memory topology. No extra cables or brackets are required.

Questions about this item

Will this 260-pin DDR4 2666 ECC SODIMM work alongside the memory already installed in my DS3622xs+?

This module is built to the DDR4 2666 (PC4 21300) specification with ECC and unbuffered operation. The DS3622xs+ will set the final speed to match the slowest module present, so mixed speeds will run at the lowest common rate.

How can I confirm the 16 GB ECC SODIMM is recognised and running at CL19 1.20 V after installation?

Open DSM Control Panel, choose Info Center and then System Report. The memory section will show 16 GB detected, ECC enabled, 2666 MT/s data rate and CL19 timings at the standard 1.20 V.

What comes in the package and is anything else required to fit it in the DS3622xs+?

The box contains one 16 GB 260-pin DDR4 2666 ECC unbuffered SODIMM (2Rx8, CL19, 1.20 V). No extra brackets, cables or tools are needed; the module slots directly into the NAS memory sockets.
