32GB DDR5-4800 ECC Registered RDIMM

This 32GB DDR5-4800 registered module delivers error-correcting code protection for servers and workstations that require data integrity. The single-rank x4 organisation suits platforms optimised for 1Rx4 population rules. It is built for administrators who need HPE-compatible memory without OEM pricing. Systems without registered DIMM support cannot use this module.

Capacity and headroom

At 32GB the stick handles typical virtualisation hosts, database buffers and multi-tenant workloads with comfortable headroom. The DDR5-4800 (PC5-38400) data rate feeds modern CPU memory controllers at rated speed. Workloads that scale beyond the installed slot count will exhaust capacity before bandwidth becomes the bottleneck. Boards limited to lower DDR5 speeds will downclock the module automatically.

Registered ECC with HPE PN P43325-B21 equivalence

The registered buffer and on-die ECC are the decisive specification; they determine whether the motherboard initialises the DIMM at all. The module carries a major-brand chipset and matches HPE part number P43325-B21 for drop-in compatibility. Lifetime warranty covers the part for the duration of the deployment. Unbuffered or non-ECC platforms will reject this memory.

Questions about this item

Will the 4800 MHz speed of this DDR5 RDIMM downclock to match slower DDR5 modules already installed?

Yes, DDR5 modules operate at the lowest common speed across all populated slots, so this 4800 MHz RDIMM will downclock to match any slower DDR5 memory present.

How can I verify the 1Rx4 ECC registered configuration is active after installation?

Check the system BIOS or UEFI memory information screen; it should report 32 GB capacity, 4800 MT/s speed, ECC enabled, registered mode, and a 1Rx4 organisation for the module.

Does the box include only the memory module or are any additional components supplied?

Only the 32 GB DDR5-4800 1Rx4 ECC registered RDIMM is included; no heatsinks, cables, or other accessories are provided.
