HPE 32GB (1x32GB) DDR5-5600 CAS-46 Dual Rank x8 Registered Smart Memory Kit

The HPE 32GB (1x32GB) DDR5-5600 CAS-46 Dual Rank x8 Registered Smart Memory Kit (P64341-B21) is a server-grade RDIMM engineered for HPE ProLiant Gen11 platforms, delivering high-bandwidth, low-latency memory performance aligned with the demands of modern datacenter and AI/ML infrastructure. Operating at DDR5-5600 MT/s with a CAS latency of 46, this module advances memory throughput over prior DDR4 generations while maintaining the signal integrity and reliability characteristics required in always-on enterprise environments. The x8 dual-rank configuration provides a balance of capacity and channel efficiency suited to memory-intensive workloads across compute-dense server deployments.

As an HPE Smart Memory module, P64341-B21 incorporates an on-module serial presence detect (SPD) that communicates directly with the HPE BIOS, enabling advanced RAS (Reliability, Availability, and Serviceability) features including memory pre-failure alerts and enhanced diagnostics surfaced through HPE iLO and Agentless Management Service. Error Correcting Code (ECC) support is inherent to the registered DIMM architecture, providing single-bit error correction and multi-bit error detection to protect data integrity under sustained workloads. The DDR5 architecture also introduces on-die ECC (ODECC) at the DRAM level, adding an additional layer of protection before data traverses the memory bus.

This memory kit is validated and tested by HPE for use in HPE ProLiant Gen11 servers, ensuring compatibility with HPE's supported memory configurations and qualification matrices. The module targets enterprise IT environments requiring high-speed, reliable memory expansion for virtualization hosts, in-memory analytics engines, AI inference nodes, and high-core-count compute platforms. Its DDR5-5600 speed rating positions it among the higher-frequency standard RDIMM offerings available for Gen11 systems, supporting throughput-sensitive applications that benefit from increased memory bandwidth relative to earlier DDR5-4800 baselines.

Ideal for

• High-density VMware vSphere or Microsoft Hyper-V virtualization hosts requiring large memory footprints across numerous concurrent virtual machines
• AI and machine learning inference servers where model parameters and intermediate activations demand high memory bandwidth and low-latency access
• In-memory database platforms such as SAP HANA or Redis operating on HPE ProLiant Gen11 servers that require validated, high-speed DRAM
• High-performance computing (HPC) nodes running memory-intensive scientific simulation or computational fluid dynamics workloads
• Enterprise data analytics clusters where columnar in-memory processing frameworks benefit from increased DDR5 bandwidth over prior generations
• Cloud-native infrastructure and container orchestration nodes (Kubernetes) requiring large working-set memory for stateful microservices and data-plane operations
