Synology NAS memory kit

This OWC kit delivers 16 GB of DDR4 ECC SODIMM memory in two 8 GB modules. It is built for Synology DiskStation DS1819+ and DS1821+ systems that require error-correcting code memory. The modules run at 2666 MHz with CL19 latency at 1.2 V.

Straightforward SODIMM install

The 260-pin unbuffered modules slot directly into the NAS memory sockets without tools. ECC function is automatic when the system firmware supports it. The only common issue is forgetting to seat both modules fully before locking the retention clips.

16 GB total capacity

Two 8 GB ranks give 16 GB of addressable memory for the DS1819+ and DS1821+. This handles typical multi-user file serving, Docker containers and virtual machines. Workloads that need more than 16 GB will require a different platform.

Perguntas sobre este artigo

How do I verify the 2666 MHz CL19 ECC SODIMM kit is running correctly in my DS1819+ after installation?

Power on the NAS and open the Info Center in DSM; the Memory section should show 16 GB total, DDR4 2666 MHz, and ECC enabled for each 8 GB module.

What comes in the box and what must I source separately for the DS1821+ upgrade?

The kit includes two 8 GB 260-pin DDR4 2666 CL19 ECC unbuffered SODIMM modules; no tools or extra parts are required for installation.

Should I choose the 16 GB 2×8 GB 2666 CL19 kit or a different capacity for my DS1819+?

This 16 GB kit (2 × 8 GB) matches the two-slot layout of the DS1819+ and DS1821+; select it when you want the maximum supported capacity at the rated 2666 MHz speed.
