Smart Memory Kit P43328-B21 HPE 32GB Dual Rank x8 DDR5-4800 EC8 Registered

The P43328-B21 HPE 32GB (1x32GB) Dual Rank x8 DDR5-4800 CAS-40-39-39 EC8 Registered Smart Memory Kit is a robust, 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, database management, and edge computing—this module delivers a balanced blend of high 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 x8 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).

Operating at a native speed of DDR5-4800 MT/s (PC5-38400) with tight CAS-40-39-39 timings, this memory kit delivers consistent, high-speed data access critical for transactional databases, virtual machine (VM) density, and real-time analytics. The dual-rank x8 configuration maximizes memory channel utilization, providing enhanced parallelism and throughput compared to single-rank modules.

Built to HPE's stringent quality standards, the P43328-B21 incorporates advanced Error Correcting Code (ECC) technology, which actively detects and corrects single-bit memory errors in real time, preventing data corruption and unplanned system crashes. The EC8 (Extended Capability 8) registered design further enhances signal stability and reliability, supporting robust Reliability, Availability, and Serviceability (RAS) features.

This Smart Memory Kit is fully qualified and optimized for HPE ProLiant Gen11 Intel-based servers, including rack, tower, and blade models, as well as Synergy compute modules. It is engineered to unlock HPE-exclusive performance and power-management features that are unavailable with generic third-party memory.

Designed for modern, power-conscious data centers, the module operates at a low 1.1V supply voltage, significantly reducing power consumption and heat generation compared to DDR4 modules. This efficiency directly lowers cooling costs and contributes to a more sustainable IT infrastructure.

• Server Virtualization & Hyper-Converged Infrastructure (HCI): Boosts VM density and performance for VMware, Hyper-V, and Nutanix environments.
• Enterprise Database Management: Enhances throughput and reduces latency for SQL Server, Oracle, and SAP HANA deployments.
• Cloud & Edge Computing: Provides reliable, high-capacity memory for public/private cloud nodes and edge server appliances.
• Business Analytics & Big Data: Accelerates data processing for BI tools, data warehouses, and real-time analytics platforms.
• General-Purpose Server Upgrades: A cost-effective, high-reliability choice for scaling memory in mainstream Gen11 server deployments.

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.

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 P43328-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.
