Synology DS2422+ 32 GB DDR4 ECC kit

This NEMIX RAM kit delivers 32 GB of DDR4 2666 ECC unbuffered SODIMM memory in two 16 GB modules. It is built for the Synology RackStation DS2422+ and uses 260-pin modules rated at 1.2 V with CL19 latency. The ECC design helps maintain data integrity in a NAS environment.

Suits DS2422+ owners adding capacity.

The kit targets administrators upgrading a Synology DS2422+ that requires ECC unbuffered SODIMMs. Builders working with consumer laptops or desktops that do not support ECC should look elsewhere, as the modules will not function correctly in those platforms.

Handles 32 GB total with dual-rank headroom

Two dual-rank 16 GB modules provide 32 GB of addressable memory for the DS2422+, giving headroom for virtual machines and large file caches. The DS2422+ memory ceiling limits further expansion, so workloads that need more than 32 GB will require a different platform.

Questions about this item

Does the Synology DS2422+ need any special BIOS setting or firmware update before I install these 2666 CL19 ECC SODIMMs?

The DS2422+ automatically detects and configures DDR4 2666 ECC unbuffered modules at 1.2 V; no manual BIOS or firmware step is required.

Will these 2Rx8 modules run reliably alongside the 8 GB stick that shipped in my DS2422+?

Yes — the kit matches the factory speed, voltage and ECC type, so the original 8 GB module and the two 16 GB sticks will operate together at 2666 MT/s.

How can I confirm the full 32 GB kit is recognised and ECC is active after installation?

Open DSM Control Panel → Info Center; the Memory line should show 32 GB total and the ECC status will read "Enabled".
