Synology DDR4 2666 ECC SODIMM Kit

This NEMIX RAM kit supplies 64GB across four 16GB DDR4 2666 modules built for Synology NAS units. Each stick is a 260-pin unbuffered ECC SODIMM running at 1.20V with CL19 latency and a 2Rx8 organisation. The modules use major OEM chips and are stress-tested for stability in always-on storage appliances.

Suited for Synology NAS expansion only

The kit targets administrators who need to maximise the supported memory capacity of a compatible Synology model. Builders working with non-Synology platforms, desktop motherboards requiring registered DIMMs, or systems limited to lower-density modules should look elsewhere. The unbuffered ECC design will not function in servers that mandate registered memory.

Four matched modules simplify installation

The package delivers a pre-matched quad-channel set so the NAS can be populated in a single step without mixing revisions. No heat spreaders are included, keeping the low-profile form factor intact for tight drive-bay clearances. No additional software or configuration utilities are bundled; the memory is recognised automatically by the Synology firmware.

Perguntas sobre este artigo

Which Synology NAS models accept this 2666 MHz DDR4 ECC SODIMM kit?

The kit is built for Synology systems that use DDR4 2666 ECC unbuffered SODIMM modules; check your NAS manual for the exact model list.

Can I mix these 16 GB 2Rx8 modules with the 8 GB sticks already in my NAS?

Mixing different capacities and ranks is not recommended; for stable ECC operation populate all slots with identical 16 GB 2Rx8 modules.

How do I confirm the NAS recognises all 64 GB at 2666 MT/s with ECC active?

After installation open the DSM Control Panel → Info Center → Memory; it should show 64 GB, 2666 MHz and ECC enabled.
