HPE 64GB (1x64GB) DDR5-5600 CAS-46 Dual Rank x4 Registered Smart Memory Kit

The HPE 64GB (1x64GB) DDR5-5600 CAS-46 Dual Rank x4 Registered Smart Memory Kit (P64340-B21) is a high-capacity, high-frequency server memory module engineered for HPE ProLiant Gen11 platforms. Built on the DDR5 architecture, it operates at 5600 MT/s with a CAS latency of 46, delivering the elevated memory bandwidth and improved power efficiency that modern datacenter, AI inference, and high-performance computing workloads demand. The Registered (RDIMM) design with dual rank x4 organization enhances signal integrity across multi-DIMM configurations, enabling stable operation in densely populated memory channels.

As an HPE Smart Memory module, this kit incorporates an integrated Serial Presence Detect (SPD) and a platform-aware identification system that allows HPE servers to recognize and validate the module at POST, unlocking full platform performance and enabling advanced RAS (Reliability, Availability, and Serviceability) features. This includes support for On-Die ECC, which catches and corrects single-bit errors within the DRAM die itself before they propagate, and compatibility with higher-level system ECC implementations supported by the host platform. The x4 die width further strengthens error correction coverage compared to x8 configurations.

With 64GB of capacity in a single DIMM, this module is well-suited for memory-intensive enterprise environments where maximizing per-slot density reduces the number of DIMMs required while achieving high total memory capacity per server node. It is specifically validated and optimized for HPE Gen11 server platforms, ensuring firmware-level compatibility, thermal management, and memory subsystem tuning aligned with HPE's quality and performance standards for production datacenter deployments.

Ideal for

• In-memory database hosting and real-time analytics platforms requiring high per-node memory capacity and bandwidth, such as SAP HANA or Oracle Database In-Memory on HPE ProLiant Gen11 servers
• AI and machine learning inference workloads where large model footprints and rapid data throughput benefit from DDR5-5600 bandwidth and high-density 64GB DIMMs
• Virtualization infrastructure running large numbers of concurrent VMs on VMware vSphere or Microsoft Hyper-V, where maximizing total usable memory per host is critical for consolidation ratios
• High-performance computing clusters executing memory-bound parallel workloads in scientific research, financial modeling, or engineering simulation environments
• Enterprise application servers running ERP, CRM, or business intelligence platforms that require large working memory sets and continuous availability with ECC protection
• Cloud service provider and hyperscale datacenter nodes where DDR5 power efficiency advantages reduce operational energy consumption at scale across high-density server deployments
