HPE Compatible DDR5 RDIMM

This 64GB DDR5 4800 ECC registered DIMM is built for HPE servers and workstations that require registered memory with error correction. The single module uses a 2Rx4 organisation and runs at 1.10V, matching the platform specifications for stable operation in enterprise environments.

Thermals and Power at 1.10V

Operating at the standard DDR5 voltage of 1.10V keeps power draw low for a 64GB registered module. The design omits a heat spreader, relying on chassis airflow to maintain safe temperatures during sustained workloads in typical server configurations.

288-Pin Registered Build Quality

The 288-pin RDIMM form factor fits DDR5 server slots that accept registered modules, and the 2Rx4 rank structure supports high-density population. Buyers needing unbuffered memory or non-ECC operation should select a different module type for their platform.

  • DDR5 4800 speed delivers high data throughput
  • ECC registered design protects data integrity
  • 1 V operation reduces power consumption

Questions about this item

How do I install this 288-pin DDR5 RDIMM in an HPE server and which step is often missed?

Power down the server, open the chassis, align the module key with the slot, press firmly until both retention clips click, then verify the new 64 GB capacity appears in the BIOS or iLO before booting the OS.

What maintenance or replacement will this ECC registered module need over its service life?

No scheduled maintenance is required; if a correctable error count rises or the module fails, replace it with an identical 64 GB DDR5 4800 CL40 2Rx4 RDIMM to keep matched ranks and ECC coverage.

What limit appears first when this 1.1 V CL40 memory runs sustained workloads on an HPE platform?

The DDR5 4800 MT/s data rate and CL40 latency set the throughput ceiling; sustained heavy traffic will saturate bus bandwidth before the 1.1 V operating voltage reaches a thermal throttle point.
