OWC 64GB (2×32GB) DDR4 2666MHz ECC SODIMM for Synology RS822+/RS822RP+

System-Specific Upgrade Kit

This 64 GB kit contains two 32 GB DDR4 ECC SODIMMs built for Synology RackStation RS822+ and RS822RP+ units. It targets administrators who need maximum supported memory for virtualization, container workloads or large file caches in these specific NAS models. Buyers whose systems use a different form factor or lack ECC support cannot use this kit.

260-Pin DDR4 Integration

Each module fits a standard 260-pin SODIMM slot and runs at 1.2 V without a heat spreader, leaving clearance for tight chassis airflow. The unbuffered, dual-rank design drops into the two available slots on the RS822 series, freeing no extra slots but delivering the full 64 GB capacity the platform accepts. JEDEC and RoHS compliance keeps the original system warranty intact.

Sustained 2666 MT/s Operation

Rated at PC4-21300 with CL19 latency, the modules maintain 2666 MT/s throughput under continuous NAS workloads such as deduplication, encryption or multi-user file serving. ECC corrects single-bit errors in real time, preventing silent data corruption during long uptime periods. Backward compatibility with 2400 MT/s and 2133 MT/s buses allows the kit to clock down automatically if the platform requires it.
