Compatible HP Replacement Module

This 32GB DDR4 2933 ECC RDIMM is built as a direct replacement for HP part number L58118-001. It targets server and workstation administrators who need registered error-correcting memory to maintain data integrity under sustained workloads. The module delivers 32GB of capacity in a single 288-pin DIMM running at 1.20V.

Registered DIMM For Multi-Module Configurations

Registered buffering reduces electrical load on the memory controller, allowing larger populations of modules per channel in supported server platforms. The 2Rx4 rank organisation and CL21 latency operate within standard DDR4 2933 timing. Buyers who need unbuffered UDIMMs or non-ECC memory for desktop platforms cannot use this module.

Tested Single Module With Lifetime Coverage

Each unit undergoes quality-assurance testing before shipment to verify reliable operation at the rated PC4-23400 speed. The package contains one 32GB stick; no additional cables, brackets or software licences are included. A-Tech backs the module with a lifetime warranty and US-based technical support for compatibility questions.

Questions about this item

What CAS latency does the module run at when the server is under continuous load?

The module operates at CL21 latency, which remains constant during sustained operation.

How much power does the 32 GB DDR4 2933 RDIMM draw and how hot does it get during all-day use?

It runs at the standard DDR4 voltage of 1.20 V; registered DIMMs at this voltage typically stay cool enough for passive server airflow.

Which motherboard slot and memory-channel configuration must the system already provide for this 2Rx4 module to work?

The system needs a DDR4 288-pin RDIMM slot and a memory controller that supports registered ECC 2Rx4 modules.
