OWC 16GB (2x8GB) DDR4 2666 ECC SODIMM memory upgrade for Synology RS822+ RS822RP+

Synology RS822+ RS822RP+ ECC SODIMM Kit

This 16GB kit contains two 8GB DDR4 2666 ECC SODIMM modules built for the Synology RS822+ and RS822RP+ RackStation units. The modules run at PC4-21300 with CL19 latency and 1.2V operation. They are unbuffered, single-rank 1Rx8 devices in the standard 260-pin form factor. JEDEC and RoHS compliance ensures a warranty-safe upgrade for these NAS platforms.

Suited for NAS owners needing ECC reliability

The kit targets administrators who want error-correcting memory in the supported Synology RackStation models to protect data integrity during file serving, virtualization or backup workloads. It will not help buyers who require registered or load-reduced DIMMs, nor those whose systems demand higher frequencies or larger per-module capacities than the 8GB density supplied here.

Sustained load behaviour in compatible NAS

Under continuous operation the modules maintain their rated 2666MT/s speed and CL19 timings at 1.2V without a heat spreader, relying on chassis airflow. Backward compatibility allows them to clock down to 2400MHz or 2133MHz if the platform requires it, preserving stability during extended multi-user access or RAID rebuilds.
