NEMIX RAM 8GB DDR4 2666 ECC Unbuffered UDIMM Synology memory upgrade

Synology-compatible ECC UDIMM

This 8 GB DDR4 2666 module is built for Synology NAS units that accept unbuffered ECC memory. It targets administrators who need to expand capacity without changing voltage or latency settings. The single-rank 1Rx8 organisation keeps the electrical load light for dense configurations. It is not for systems that require registered DIMMs or non-ECC consumer modules.

Unbuffered 288-pin design

The stick uses a standard 288-pin DDR4 edge connector and runs at 1.20 V, matching the platform specification. No heat spreader is fitted, so clearance inside compact NAS chassis is maximised. Major OEM chips from Samsung Micron or Hynix are selected for supply continuity. Builders who need tall heatsinks or RGB lighting will not find them here.

Single-module package

The box contains one 8 GB UDIMM and no additional cables, brackets or software media. Installation follows the Synology service manual; no proprietary tools are required. Lifetime replacement coverage is backed by the distributor's support team. Users who expect bundled diagnostics or firmware utilities should source those separately.
