Synology DDR4 ECC RDIMM
This 16 GB DDR4 2666 module is built for Synology FlashStation NAS units that require registered ECC memory. It delivers 1.2 V operation with CL19 latency in a single 288-pin RDIMM. IT administrators upgrading compatible systems gain error correction and registered buffering for data integrity.
Thermals noise and power
The module runs at the standard DDR4 voltage of 1.20 V without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during normal NAS workloads. Silent solid-state operation adds no audible noise to the rack environment.
Sustained load behaviour
Under continuous read and write cycles the ECC logic corrects single-bit errors while the 2Rx4 organisation maintains signal stability across ranks. Stress-tested modules preserve throughput without throttling during extended backup or virtualization tasks. Compatibility validation targets the Synology D4RD-2666-16G specification for reliable long-term service.

Domande su questo articolo
How do I install this 288-Pin DDR4 RDIMM in my Synology NAS, and what step is often missed?
Power down the NAS, open the chassis, align the notch on the 288-Pin module with the slot key, press firmly until both retention clips click, then verify the new 16GB capacity in DSM before closing the case.
What maintenance or replacement will this ECC Registered module need over time?
No scheduled maintenance is required; the module either runs reliably for the system's life or is replaced under the lifetime warranty if a memory error appears.
What limit appears first when this CL19 1.20V kit runs sustained workloads?
The DDR4 2666 bandwidth ceiling is reached before thermal throttling, since the module has no heat spreader and operates at standard 1.20V.
