HPE 64GB Dual Rank x4 DDR5-4800 EC8 Registered Smart Memory Kit P43331-B21

The P43331-B21 HPE 64GB (1x64GB) Dual Rank x4 DDR5-4800 CAS-40-39-39 EC8 Registered Smart Memory Kit is a high-capacity, enterprise-grade memory solution purpose-built for HPE ProLiant Gen11 server platforms. Engineered to address the escalating demands of modern data center workloads—including virtualization, cloud infrastructure, large-scale database management, and high-performance computing—this module delivers a balanced blend of massive capacity, reliable performance, and energy efficiency.

By leveraging cutting-edge DDR5 technology, it provides a substantial leap in bandwidth and latency improvements over legacy DDR4 solutions, enabling servers to efficiently scale with multi-core processors and data-intensive applications. The dual-rank x4 architecture, combined with EC8 Registered and ECC capabilities, ensures exceptional signal integrity, data protection, and system uptime, making it an ideal upgrade for businesses seeking to optimize performance while controlling total cost of ownership (TCO).

• Server Virtualization & Hyper-Converged Infrastructure (HCI): Boosts VM density and performance for VMware, Hyper-V, and Nutanix environments, enabling efficient resource allocation.
• Enterprise Database Management: Enhances throughput and reduces latency for SQL Server, Oracle, and SAP HANA deployments, supporting large-scale transaction processing.
• Cloud & Edge Computing: Provides reliable, high-capacity memory for public/private cloud nodes and edge server appliances, ensuring consistent performance in distributed environments.
• Big Data & Business Analytics: Accelerates data processing for BI tools, data warehouses, and real-time analytics platforms, reducing query times.
• High-Performance Computing (HPC): Powers scientific simulations, computational research, and AI inference workloads, delivering the high bandwidth required for complex calculations.

A1: No. This memory kit is specifically designed and qualified for HPE ProLiant Gen11 Intel-based servers only. It is not backwards-compatible with Gen10 or earlier platforms due to differences in memory controller architecture and power requirements.

A2: For optimal performance and stability, HPE strongly recommends populating servers with identical memory modules (same part number, capacity, speed, and rank). Mixing different memory configurations may result in reduced performance, compatibility issues, or system instability. Always adhere to the memory population guidelines for your specific server model.

A3: EC8 (Extended Capability 8) Registered memory uses a register to buffer the address and control signals, improving signal integrity and allowing for larger memory configurations. This is crucial for enterprise servers as it supports higher memory capacities and more DIMMs per channel, while enhancing overall system stability under heavy loads.

A4: Error Correcting Code (ECC) continuously scans for and automatically corrects single-bit data errors that can occur due to electrical interference or cosmic radiation. This prevents silent data corruption and system crashes, which is vital for maintaining data integrity in mission-critical applications.

A5: The P43331-B21 includes a 3-year limited warranty covering defects in materials and workmanship. Warranty support is available through HPE's global support channels, including online case management, technical support chat, and authorized service partners.
