HPE Server Memory Upgrade

This 16GB DDR5 RDIMM is built for HPE servers and workstations that require registered ECC memory. It operates at 4800MHz with a CL40 latency and 1.1V voltage. The module uses a 288-pin form factor with a 1Rx8 rank configuration.

Registered ECC Module Design

The registered buffer reduces electrical load on the memory controller for stable operation in multi-module configurations. On-die ECC corrects single-bit errors to protect data integrity in mission-critical workloads. Major OEM chips from Samsung, Micron or Hynix are used. No heat spreader is included.

Suited for Compatible HPE Systems

This upgrade fits administrators expanding memory in qualified HPE platforms using the P43322-K21 part number. Builders needing unbuffered UDIMMs, non-ECC memory, or different speeds should look at other products.

Questions sur cet article

Will the DDR5 4800 RDIMM need a heat spreader added later for sustained server workloads?

The module ships without a heat spreader; HPE server chassis airflow is designed to cool bare registered DIMMs at 1.10 V under continuous load.

What limits throughput first when the 1Rx8 ECC module runs at 4800 MT/s all day?

The CL40 CAS latency sets the timing ceiling; registered buffering adds one cycle but prevents signal degradation that would otherwise throttle sustained bandwidth.

How much noise and heat does the 288-pin registered DIMM generate at 1.1 V in an HPE system?

Solid-state DRAM produces no acoustic noise; at 1.1 V the thermal output is low enough for standard server fan curves without extra cooling.
