32GB DDR4 2933MHz ECC RDIMM

This 32GB DDR4 2933MHz ECC RDIMM module provides registered, error-correcting memory for server and workstation platforms. It operates at PC4-23400 speed with a CL21 latency and 1.20V voltage. The single-rank 1Rx4 organisation uses Micron chipset components on a 288-pin DIMM form factor. It serves administrators who need validated capacity expansion for compatible systems.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation, helping maintain signal integrity across all 72 bits including ECC. The 1.20V standard voltage supports stable throughput without elevated power draw during extended workloads. Quality assurance testing verifies reliable performance under prolonged utilisation typical of server environments.

DDR4 interface limits

The DDR4 2933MHz interface delivers 23400 MB/s theoretical bandwidth per module, constraining maximum throughput to this ceiling regardless of processor capability. Single-rank 1Rx4 density limits total capacity per channel compared to dual-rank alternatives. Compatibility depends on platform support for registered ECC DIMMs at this specific speed and voltage.

Questions about this item

How much power does this 1.20 V DDR4 2933 MHz ECC RDIMM draw under continuous server load?

The module operates at the standard DDR4 voltage of 1.20 V. Registered ECC DIMMs typically consume slightly more power than unbuffered modules due to the register, but exact draw depends on your platform and workload.

What must my motherboard provide to run this 288-pin DDR4 2933 MHz registered ECC module?

A DDR4 RDIMM slot with ECC support, 1.2 V operation and a memory controller qualified for 2933 MHz registered DIMMs.

Will this CL21 1Rx4 registered DIMM work alongside older DDR4 modules in the same system?

Mixing ranks, speeds or latencies is possible but not guaranteed; the system will run all modules at the lowest common speed and timing.
