HPE DDR5-4800 Registered DIMM

This 32 GB HPE P43328-B21 module is built for server, rack and blade platforms that require registered DDR5 memory. It targets administrators expanding capacity in enterprise environments where data integrity and sustained uptime are priorities.

Thermals and power efficiency

Operating at 1.10 V, the dual-rank DIMM is designed for lower power draw than previous DDR4 3200 MT/s modules. HPE qualification selects high-quality DRAM to maintain stability without excessive heat in dense chassis configurations.

Sustained load behaviour

Under continuous workloads such as virtualization or large databases, the registered signal buffering and CL40 latency help maintain consistent throughput at 4800 MT/s. Rigorous testing unlocks platform-specific performance features available only with HPE servers.

Questions sur cet article

How is the 288-pin DDR5 DIMM installed, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module is seated evenly; the step often missed is confirming both clips lock simultaneously.

What maintenance or replacement will the 32GB dual-rank module need later?

No routine maintenance is required; replacement is only needed if a memory error appears or capacity must be increased beyond 32GB.

What limit appears first under sustained load with 1.10V DDR5-4800 CL40 memory?

Thermal throttling from the memory controller typically limits sustained throughput before the module reaches its rated voltage or latency ceiling.
