NEMIX RAM 128GB (4x32GB) DDR4 2666 ECC RDIMM Synology FS3410 memory upgrade

128 GB DDR4 kit for Synology FS3410

This 128 GB kit supplies four 32 GB registered DIMMs built for the Synology FlashStation FS3410. Each module carries ECC and parity protection for data integrity in a network-attached storage environment. The kit targets administrators who need to expand memory capacity on this specific platform.

Registered ECC RDIMM at DDR4 2666

The modules run at DDR4 2666 (PC4-21300) with a CAS latency of 19 and a 1.2 V operating voltage. Registered buffering and 2Rx4 organisation allow the memory controller to address all four DIMMs without signal degradation. This specification is the single factor that determines whether the kit will post and run stably in the FS3410.

Sustained load behaviour in a NAS chassis

Under continuous workloads such as deduplication, encryption or virtual-machine hosting, the registered design keeps command and address signals clean across all ranks. ECC corrects single-bit errors on the fly, preventing silent data corruption during long uptime periods. The absence of heat spreaders means airflow through the server chassis must be sufficient to maintain rated temperature.
