32GB ECC SODIMM kit for Synology DS2419+II

This dual-channel kit delivers 32GB of DDR4 2666 ECC unbuffered memory in two 16GB modules. It targets administrators who need verified compatibility with the Synology DiskStation DS2419+II and want error-correcting protection for data integrity.

2Rx8 organisation and 1.20V operation

Each module uses a 2Rx8 layout at CL19 latency and runs at the standard 1.20V. The 260-pin SODIMM form factor fits the NAS memory slots without a heat spreader, keeping the profile low for tight chassis spacing.

2666 MT/s DDR4 speed grade

The PC4-21300 rating confirms 2666 MT/s throughput, which matches the DS2419+II memory controller specification. Systems that require a different speed grade or non-ECC modules will not accept this kit.

Questions about this item

Will the ECC modules ever need scheduled replacement under normal NAS workloads?

The kit uses ECC unbuffered DDR4 SODIMMs rated at 1.2 V with CL19 timing; they have no moving parts and no manufacturer-specified replacement interval.

What thermal limit appears first when the DS2419+II runs sustained workloads with this memory?

Modules operate at standard 1.2 V without heat spreaders, so the NAS chassis airflow limit is reached before the memory’s own thermal threshold.

How much power does the 32 GB kit draw when the Synology runs 24/7?

Each 16 GB module runs at 1.2 V DDR4 voltage, so total draw stays within the platform’s standard SODIMM power envelope.
