Synology DS3622xs+ ECC memory kit

This 16 GB kit supplies two 8 GB DDR4 2666 SODIMM modules built with ECC unbuffered chips. It targets administrators who need to expand the memory of a Synology DiskStation DS3622xs+ NAS for virtualisation or heavy file workloads.

Sustained-load behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, protecting data integrity on long-running services. The CL19 latency and 1.20 V voltage remain stable across extended backup, deduplication or database tasks.

Thermals and power

Modules run without heat spreaders at the standard DDR4 SODIMM voltage, drawing minimal power inside the NAS chassis. Passive airflow from the system fans keeps temperatures low and acoustic output negligible during normal use.

Questions about this item

How much heat does the 1.2 V DDR4 2666 kit add when the NAS runs all day?

The modules run at 1.20 V without a heat spreader, so they add minimal heat inside the Synology DS3622xs+ chassis during continuous operation.

What must the Synology DS3622xs+ already have for this 260-pin ECC SODIMM kit to work?

The NAS needs free 260-pin DDR4 SODIMM slots that support unbuffered ECC memory at 2666 MT/s.

Will the CL19 1Rx8 modules run alongside the original memory in a DS3622xs+?

Yes, the kit matches the DDR4 2666 ECC unbuffered specification used by the DS3622xs+, so it can operate with the factory-installed modules.
