OWC 16GB DDR4 2666MHz CL19 ECC SODIMM 2Rx8 1.2V for Synology DS2419+ DS2419+II memory upgrade

Compatible NAS upgrade

This 16GB DDR4 SODIMM is built for Synology DiskStation DS2419+ and DS2419+II systems. It adds ECC protection to a single slot. The module suits administrators who need reliable capacity for virtualisation or heavy file workloads. It is not for buyers who want non-ECC memory or a different form factor.

Slot-ready integration

The 260-pin stick drops straight into an empty SODIMM socket without extra cables or brackets. Running at 1.2V, it keeps the power budget low and leaves headroom for other components. Backward compatibility with 2400MHz and 2133MHz buses lets it work in mixed-speed configurations. Builders who need registered DIMMs or a 288-pin desktop form factor cannot use this module.

Cool, quiet operation

No heat spreader means the module relies on the NAS chassis airflow, which is sufficient at the rated 1.2V. ECC logic adds minimal latency while correcting single-bit errors on the fly. Power draw stays modest under typical multi-user loads. Environments without active case ventilation may see higher temperatures than specified.
