HPE-Compatible DDR5 4800 RDIMM

This 128 GB DDR5 4800 ECC registered module is built for HPE servers and workstations. It carries the PC5-38400 speed rating and a CAS latency of CL40. The single 4Rx4 rank design targets administrators who need maximum capacity per slot in supported platforms.

Single-Module 128 GB Upgrade

The stick occupies one 288-pin DDR5 RDIMM slot and runs at 1.10 V. Registered buffering and on-die ECC protect data integrity without requiring additional hardware. It matches HPE part numbers P46972-H21, P58360-H21 and P62605-B21 for direct replacement or capacity expansion.

Passive Cooling at 1.10 V

No heat spreader is fitted, so airflow from the chassis fans cools the DRAM directly. The low 1.10 V operating voltage limits power draw per module, keeping thermal contribution modest in densely populated memory channels. Acoustic impact is negligible because the module adds no moving parts.

Questions about this item

What is the CAS latency of this DDR5 module?

This module runs at CL40 CAS latency, which is the timing the memory controller will use for every access cycle.

Does the module include a heat spreader for thermal management?

No, the specification lists no heat spreader, so the bare PCB relies on chassis airflow for cooling during continuous operation.

Which HPE part numbers is this 128 GB RDIMM validated against?

It is compatible with HPE part numbers P46972-H21, P58360-H21 and P62605-B21 for direct replacement.
