OWC 8GB DDR4 2666 CL19 ECC UDIMM 1Rx8 1.2V 288-Pin for Synology RS1619xs+ RS2818RP+

Targeted NAS Memory Upgrade

This 8 GB DDR4 ECC UDIMM is built for Synology RackStation RS1619xs+ and RS2818RP+ units that require JEDEC-standard 2666 MHz memory with error correction. It suits administrators who need to expand capacity in validated 1U and 2U rack appliances without changing voltage or form factor.

Build Integration

The module uses a standard 288-pin unbuffered layout at 1.2 V, so it fits directly into the DIMM slots on the listed RackStation models and runs alongside existing 2133 MHz or 2400 MHz sticks at the lower common speed. ECC support protects stored data from single-bit errors, while the single-rank 1Rx8 organisation leaves additional slots free for further expansion.

Sustained Operation

Rated at CL19 latency and PC4-21300 bandwidth, the DIMM maintains specified timings during continuous file-serving, backup and virtualization workloads typical of NAS environments. JEDEC and RoHS compliance ensures stable voltage regulation and thermal behaviour over long duty cycles, and the absence of a heat spreader keeps the profile low for dense rack chassis airflow.
