Server-grade ECC module

This 32GB DDR4 2133MHz CL15 2Rx4 ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It will not work in standard desktop computers and cannot be mixed with unbuffered modules.

Registered 288-pin form factor

The module fits a 288-pin DDR4 slot and presents a registered signal to the memory controller, reducing electrical load on the bus. It operates at 1.2V and follows JEDEC PC4-17000 timing, so it installs without configuration changes on compatible platforms.

Sustained data integrity

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing silent data corruption in long-running workloads. Registered buffering keeps signal quality stable across full DIMM populations under extended load.

Questions about this item

Does the CL15 latency limit throughput when the module runs at 2133 MHz continuously?

CL15 is the rated timing at 2133 MHz; the module meets JEDEC specifications for sustained operation at that speed.

How much heat does the 1.2 V registered DIMM produce during all-day server workloads?

The module operates at 1.2 V without a heat spreader, relying on normal chassis airflow for cooling in server and workstation environments.

Must the system already support 288-pin DDR4 ECC registered memory for this 32 GB module to work?

Yes, the platform must accept 288-pin DDR4 ECC registered RDIMMs; it will not function in standard desktop or unbuffered memory slots.
