Synology DS2419+ memory kit

This OWC kit provides 16 GB of DDR4 ECC SODIMM memory in a matched pair of 8 GB modules. It is built for the Synology DiskStation DS2419+ and DS2419+II NAS systems. The modules run at 2666 MHz with CL19 latency and operate at the standard 1.2 V. ECC support helps protect data integrity in always-on storage appliances.

NAS owners needing ECC SODIMMs

The 260-pin unbuffered design fits the target Synology models and is backward compatible with 2400 MHz and 2133 MHz slots. Builders using desktop DIMM slots, non-ECC platforms or registered memory requirements cannot use these modules. The kit is also unsuitable for systems limited to single-rank 2Rx8 configurations.

Sustained NAS workloads

Under continuous file-serving or backup tasks the ECC circuitry corrects single-bit errors without halting the system. Unbuffered operation keeps latency low during steady metadata and parity calculations. JEDEC-standard voltage and timings maintain stability across long uptime periods without thermal throttling.

Questions about this item

Does the Synology DiskStation DS2419+ need both SODIMM slots filled for this 16 GB kit to work?

The kit contains two 8 GB modules; the DS2419+ has two DDR4 SODIMM slots, so both must be populated to reach 16 GB.

Will these 2666 MHz modules run at full speed if my DS2419+II currently has 2133 MHz memory installed?

The modules are backward compatible with 2133 MHz and 2400 MHz, so they will operate at the speed of the slowest installed memory.

How can I confirm the ECC function is active after installing the kit in my DS2419+?

Check the DSM Resource Monitor or system log; it will report ECC memory detected and show corrected error counts if any occur.
