Server-grade ECC Registered RDIMM

This 32GB DDR4 module runs at 2133 MHz with CL15 latency and 1.2V operation. It uses a 2Rx4 registered design with on-board ECC for data integrity in server, workstation and NAS environments. The 288-pin form factor follows JEDEC PC4-17000 specifications.

Requires registered DIMM slots

The module fits 288-pin DDR4 sockets that support registered memory and cannot be mixed with unbuffered or load-reduced DIMMs. It targets compatible Synology FS3017, FS2017 and RS18017xs+ units among other qualified systems. No heat spreader is included, so airflow across the PCB must be provided by the chassis.

Steady throughput under continuous workloads

Registered buffering reduces electrical load on the memory controller during sustained read-write cycles. ECC correction handles single-bit errors without halting the system. JEDEC-compliant timing and voltage deliver predictable bandwidth for virtualisation, file services and database tasks that run for extended periods.

Questions about this item

Does the CL15 latency limit throughput under sustained server workloads?

The module runs at CL15 timing as specified. CAS latency is a fixed parameter of the DDR4 2133 design and does not change during extended operation.

How much heat does the 1.2V registered DIMM produce when running continuously?

Operating at 1.2V with no heat spreader, the 2Rx4 registered DIMM draws minimal power and generates low heat typical for DDR4 2133 server memory.

Which NAS models must I already own for this 288-pin ECC RDIMM to work?

The module is validated for Synology FS3017, FS2017 and RS18017xs+ systems that accept DDR4 2133 ECC registered DIMMs.
