HPE 16GB DDR5 Registered DIMM

This HPE module provides 16GB of DDR5 memory rated at 4800MHz with a CL40 latency. It operates at 1.10V using a registered 288-pin DIMM form factor designed for server, rack and blade platforms. The single-rank configuration supports Intel XMP 3.0 profiles for validated performance tuning.

Thermals and power at standard speed

Running at the rated 4800MHz frequency and 1.10V, the module draws minimal power appropriate for dense server deployments. Registered buffering reduces electrical load on the memory controller, contributing to stable thermals inside populated chassis. Passive operation relies on system airflow rather than module-mounted cooling.

Behaviour under sustained load

The registered design maintains signal integrity during continuous workloads across all populated slots. Single-rank organisation allows consistent bandwidth delivery without the timing penalties seen in dual-rank alternatives under prolonged stress. Intel XMP 3.0 support ensures the programmed profile remains stable over extended operating periods.

Questions sur cet article

How do I install this 288-pin DDR5 registered DIMM and what step do people often miss?

Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the module runs at 4800 MHz with CL40 timings.

What maintenance or replacement will this 1.10V DDR5 module need over time?

No scheduled maintenance is required; if a memory error appears in the server event log, replace the affected 16 GB DIMM with an identical registered module.

What limit appears first when this single-rank DDR5 memory runs under sustained load?

The CAS latency of CL40 at 4800 MHz sets the timing floor; sustained throughput cannot exceed the PC5-38400 bandwidth ceiling.
