Synology RS2423RP+ ECC Kit

This 32 GB kit contains two 16 GB DDR4 2666 ECC unbuffered UDIMM modules built for the Synology RackStation RS2423RP+. Each stick runs at 1.2 V with a CL19 latency and uses major OEM Samsung, Micron or Hynix chips.

Dual-channel 288-pin upgrade

The pair installs in the NAS's two DDR4 slots to deliver 32 GB of error-correcting memory without registered buffering. No heat spreader is fitted, so the modules sit flush in the standard 288-pin sockets and leave surrounding components unobstructed.

Sustained ECC stability

All modules are stress-tested under load before shipping to verify long-term reliability in continuous NAS workloads. The ECC logic corrects single-bit errors on the fly, protecting data integrity during extended file serving, backup and virtualization tasks.
