HPE Compatible DDR5 RDIMM

This 32GB DDR5 4800 ECC RDIMM is built for HPE servers and workstations that require registered memory with error correction. The single-rank 1Rx4 module runs at 1.1V and targets IT professionals who need reliable capacity upgrades for mission-critical workloads.

Installation and Common Issues

Installation follows standard DDR5 RDIMM procedures: power down the system, open the chassis, align the 288-pin module with the slot key, and press firmly until the retention clips engage. The most frequent issues are mixing registered and unbuffered DIMMs, exceeding the platform's maximum rank count per channel, or failing to update the system firmware before adding new modules.

Pre-Order Compatibility Checks

Verify that your HPE server or workstation supports DDR5 4800 registered ECC RDIMMs and accepts 1Rx4 organization at the target capacity. Confirm the memory population rules for your specific model, including maximum modules per channel and any required slot-filling order, by consulting the platform's technical documentation before placing the order.

Questions about this item

How can I verify the module is running at 4800 MT/s with CL40 after installation?

Enter the server BIOS or UEFI and confirm the memory speed reads 4800 MT/s and CAS latency shows CL40; the registered ECC design will also report corrected error counts if any occur.

What is included in the package and do I need any extra parts?

The box contains one 32 GB 288-pin DDR5 RDIMM; no heat spreader, cables or additional modules are supplied.

Which capacity and rank option should I select for a single-slot upgrade?

Choose the 32 GB 1Rx4 module (part number MR38400-314K1) for a single-slot registered ECC upgrade.
