128GB DDR5 ECC RDIMM for HPE Workstations

This 128GB registered DDR5 module targets administrators upgrading HP Z8 G5 or Z8 Fury G5 workstations. It delivers error-correcting, registered memory for mission-critical workloads. The single-stick design suits systems with limited DIMM slots. It is not for consumer desktops or laptops that cannot accept registered ECC memory.

4Rx4 DDR5-4800 CL40 at 1.1V

The module runs at DDR5-4800 (PC5-38400) with a CAS latency of 40 and operates at 1.1V. Its 4Rx4 organisation and registered buffer are the defining specifications that determine motherboard compatibility. Systems requiring different rank configurations or unbuffered DIMMs will not accept this part.

128GB capacity per 288-pin module

One module provides 128GB, allowing high-density configurations in supported HPE platforms. Large datasets, virtualisation hosts and in-memory databases benefit from the headroom. Workloads exceeding the per-slot limit or needing unregistered memory must choose a different module type.

Highlights

  • DDR5 4800 MT/s speed accelerates data throughput
  • ECC registered design protects critical workloads
  • 1 V operation reduces power draw
  • 288-pin RDIMM form factor fits HPE Z8 G5 workstations

Questions about this item

What does the 4800 MT/s speed mean once the module is installed in a compatible workstation?

The module runs at DDR5-4800, delivering a peak data rate of 38400 MB/s when the system memory controller operates at the rated frequency.

How does the registered ECC design affect the memory bus in practice?

Registered buffering reduces electrical load on the memory controller, while ECC detects and corrects single-bit errors for improved data integrity.

Will the 288-pin RDIMM fit in a standard HP Z8 G5 DIMM slot?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots used in the HP Z8 G5 and Z8 Fury G5 workstations.
