Synology RS1619xs+ 64GB DDR4 ECC kit

This NEMIX RAM kit supplies 64GB of DDR4 2666 memory across four 16GB unbuffered ECC UDIMM modules. It is built for the Synology RackStation RS1619xs+ NAS and uses standard 288-pin DDR4 form factor. The modules operate at 1.2V with CL19 timing and 2Rx8 organisation.

ECC unbuffered DDR4 2666 for RS1619xs+

The decisive specification is ECC unbuffered DDR4 2666 (PC4-21300) in a 288-pin UDIMM package. The RS1619xs+ requires this exact combination of error correction, voltage and speed; registered or non-ECC modules will not work in this system.

Four-slot population frees no additional bays

Installing the four 16GB modules occupies every memory slot on the RS1619xs+, delivering the full 64GB capacity in a single step. No further memory expansion is possible without removing modules, so the kit suits buyers who want the maximum supported configuration immediately.

Perguntas sobre este artigo

What does the 2666 MHz speed mean once the kit is installed in a Synology RS1619xs+?

The memory runs at DDR4 2666 (PC4-21300) with CL19 latency, delivering the rated throughput the NAS platform expects for this configuration.

How does the 288-pin DDR4 ECC UDIMM interface limit what the modules can do in practice?

The unbuffered 288-pin DDR4 ECC UDIMM form factor fits the RS1619xs+ memory slots and provides error-correcting code support without registered buffering.

What physical space and power do the four 16 GB sticks need to fit and run?

Each 16 GB module is a standard-height 288-pin UDIMM without a heat spreader, operates at 1.20 V, and the kit occupies four DIMM slots.
