  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 32 GB capacity expands server memory headroom
  • DDR5 4800 speed delivers high bandwidth throughput
  • ECC registered design protects data integrity
  • 1 V operation reduces power consumption
  • Compatible with HPE P46968-H21 P58356-H21 P62603-B21

Capacity and form factor

This module provides 32GB of DDR5 memory in a single 288-pin registered DIMM. It operates at 4800MHz with a CAS latency of 40 and runs at 1.10V. The 2Rx8 organisation and on-die ECC suit enterprise workloads that demand data integrity.

Server and workstation fit

IT teams maintaining HPE platforms referenced as P46968-H21, P58356-H21 or P62603-B21 can use this stick for a direct upgrade. Builders of custom desktops or consumer laptops should look elsewhere because the registered design and ECC function require a compatible server chipset.

Registered ECC DDR5 specification

The registered buffer and error-correcting code are the decisive attributes; without a motherboard that explicitly supports registered DDR5 ECC RDIMMs the module will not function.

Questions about this item

How much heat does a 1.10 V DDR5 4800 CL40 module add when the server runs continuously?

At 1.10 V the DDR5 4800 CL40 RDIMM runs at standard JEDEC voltage, so its thermal contribution matches other registered DDR5 modules of the same density and rank.

What must the system already provide to use this 288-pin ECC RDIMM?

A DDR5-compatible HPE server or workstation motherboard with registered DIMM slots and BIOS support for 2Rx8 ECC modules at 4800 MT/s.

Can this 2Rx8 CL40 stick share channels with older DDR5 4800 modules that have different rank or latency?

Mixing ranks or CAS latencies on the same channel is not recommended; populate identical 2Rx8 CL40 modules per channel for stable operation.
