NEMIX RAM 16GB DDR4 2666 PC4-21300 CL19 2Rx8 1.2V 288-pin ECC RDIMM server RAM

QNAP NAS 16 GB DDR4 ECC RDIMM

This 16 GB DDR4 2666 MHz registered DIMM adds error-correcting memory to compatible QNAP NAS devices. It targets IT professionals who need data-integrity protection for mission-critical storage workloads. The module is built with major OEM DRAM and validated for server-grade reliability.

Capacity and headroom

A single 16 GB rank of 2Rx8 organisation suits multi-user file serving, virtualisation hosts and backup targets that benefit from ECC. Workloads that exceed this capacity will require additional DIMM slots or higher-density modules. The CL19 latency and PC4-21300 bandwidth match the platform's native memory controller limits.

Thermals and power

Operating at 1.20 V without a heat spreader, the module runs cool inside typical NAS chassis airflow. Registered buffering reduces electrical load on the memory bus, helping system stability during sustained write-heavy tasks. Power draw remains low enough for dense multi-DIMM configurations without supplemental cooling.
