Synology FS3400 DDR4 ECC RDIMM

This 32 GB DDR4 2666 MHz ECC RDIMM is built for the Synology FlashStation FS3400 NAS. The registered design adds signal integrity for multi-module server boards. ECC protects stored data against single-bit errors during intensive workloads. It targets administrators who need validated capacity expansion for this platform.

Thermals noise and power draw

Operating at 1.20 V the module draws minimal power inside a populated NAS chassis. No heat spreader is fitted so airflow across the bare PCB manages thermals. Registered buffering reduces electrical loading on the memory bus during sustained transfers. Silent passive cooling suits the rackmount environment.

Build quality and daily implications

The 288-pin RDIMM keying prevents insertion into incompatible desktop slots. 2Rx4 organisation fits the FS3400 memory controller without configuration changes. Major OEM chips from Samsung Micron or Hynix are stress tested under load before shipping. Single-module packaging allows staggered upgrades across available slots.

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM in a Synology FS3400, and what step is commonly missed?

Power down the NAS, open the chassis, align the module notch with the slot key, press firmly until both retention clips lock, then verify the 32GB capacity in DSM before closing the case.

What maintenance or replacement will this 32GB ECC RDIMM need over time?

No scheduled maintenance is required; the module is validated for continuous operation and carries a lifetime replacement guarantee if a fault ever develops.

What limit appears first when this CL19 2666MHz registered memory runs sustained workloads?

The CAS latency of 19 cycles at 2666 MT/s sets the baseline response time, so latency-sensitive tasks hit that timing ceiling before bandwidth saturates.
