NEMIX RAM 16GB DDR4 2666MHz ECC Unbuffered SODIMM 2Rx8 CL19 1.2V 260-pin Synology DS2419+II memory upgrade

16GB DDR4 ECC SODIMM for Synology DS2419+II

This 16 GB DDR4 2666 MHz ECC unbuffered SODIMM is built for the Synology DiskStation DS2419+II. It adds error-correcting memory to a NAS that runs 24/7 workloads such as file serving, backup and virtualization. The module uses major OEM chips from Samsung, Micron or Hynix and carries part number MSE21300-628K1. It targets administrators who need validated compatibility rather than generic consumer memory.

Thermals noise and power at 1.2 V

Operating at 1.20 V, the module draws minimal power and produces little heat inside the sealed NAS chassis. No heat spreader is fitted, so airflow from the system fans passes directly over the DRAM packages. The low voltage and unbuffered design keep acoustic impact negligible during sustained read and write cycles. Power consumption stays within the platform's standard memory budget without extra cooling requirements.

Single module packaging and validated compatibility

The package contains one 260-pin SODIMM rated CL19 2Rx8 with no additional cables, tools or software. Compatibility is verified for the DS2419+II, reducing the risk of POST failures or data corruption that can occur with unqualified sticks. Installers simply insert the module into an available slot following the NAS manual. No firmware updates or configuration utilities are supplied or required.
