32 GB DDR4-2933 Registered ECC Module

This 32 GB DDR4-2933 module is built for servers and workstations that require error-correcting registered memory. It operates at PC4-23400 with a CAS latency of CL21 and uses a 288-pin form factor. The dual-rank 2Rx4 organisation helps populate high-density configurations efficiently.

Registered ECC Design for Multi-DIMM Platforms

Registered buffering reduces electrical load on the memory controller, allowing more modules per channel than unbuffered alternatives. ECC circuitry detects and corrects single-bit errors to protect data integrity in always-on workloads. The module fits standard 288-pin DDR4 slots that support registered memory.

Suited for Cisco UCS and Compatible Servers

This module suits administrators expanding memory in platforms qualified for PC4-23400 registered ECC DIMMs. It is not intended for consumer desktops or laptops that accept only unbuffered non-ECC memory. Buyers needing different capacities, speeds or rank configurations should verify their system's qualified-vendor list before ordering.

Questions about this item

Will the CL21 latency become a bottleneck during sustained heavy workloads?

CL21 is the rated CAS latency at 2933 MHz; it is a fixed timing parameter, not a variable that degrades or throttles under load.

How much heat and power does a 32 GB registered DDR4-2933 module produce when running continuously?

Registered DDR4 modules run at standard DDR4 voltage; the dual-rank 32 GB design draws typical server DIMM power and is cooled by normal chassis airflow.

Does my server need a 288-pin DDR4 slot that supports registered ECC memory for this module to work?

Yes — the module is a 288-pin DDR4 registered ECC DIMM (2Rx4, PC4-23400) and requires a compatible registered-ECC slot.
