HPE 16GB Dual Rank x8 DDR5-5600 EC8 Registered Smart Memory Kit P64705-B21

The P64705-B21 HPE 16GB (1x16GB) Single Rank x8 DDR5-5600 CAS-46-45-45 EC8 Registered Smart Memory Kit is a high-performance, enterprise-grade memory solution purpose-built for HPE ProLiant Gen11 server platforms. Engineered to deliver exceptional speed, reliability, and energy efficiency, this module is optimized for modern data center workloads, including virtualization, cloud infrastructure, business applications, and edge computing.

Leveraging cutting-edge DDR5 technology with a native speed of 5600 MT/s (PC5-44800) and precise CAS-46-45-45 timings, it provides a significant performance boost over legacy DDR4 memory, enabling faster data access and improved system responsiveness. The single-rank x8 (1Rx8) architecture ensures optimal compatibility and performance in single-socket and multi-socket server environments, while the EC8 Registered design and advanced ECC capabilities deliver robust data protection and signal integrity.

Integrated with HPE SmartMemory technology, this kit offers seamless compatibility, proactive health monitoring, and exclusive performance features, making it the ideal choice for businesses seeking to enhance server performance while maintaining mission-critical uptime and controlling total cost of ownership (TCO).

Operating at a blazing-fast DDR5-5600 MT/s data rate with tight CAS-46-45-45 latency timings, the P64705-B21 delivers exceptional memory bandwidth and low-latency data access. This high-speed performance is critical for accelerating application load times, improving transaction processing speeds, and enhancing overall system responsiveness in virtualized environments and cloud-native applications.

The single-rank x8 (1Rx8) configuration is perfectly balanced for mainstream enterprise workloads, providing efficient memory channel utilization and consistent performance across a wide range of server applications.

Built to HPE's rigorous quality standards, this memory kit incorporates advanced Error Correcting Code (ECC) technology that actively detects and corrects single-bit memory errors in real time, preventing data corruption and unplanned system outages. The EC8 (Extended Capability 8) registered design further enhances signal stability and reliability, supporting robust Reliability, Availability, and Serviceability (RAS) features essential for mission-critical operations.

Full integration with the HPE Active Health System enables continuous, proactive monitoring of memory health, providing early failure alerts and simplifying diagnostics to minimize downtime.

The P64705-B21 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 unlocks HPE-exclusive performance and power-management features that are unavailable with generic third-party memory, ensuring maximum system stability and efficiency.

The standard 288-pin RDIMM form factor allows for straightforward, hot-swap capable installation, facilitating non-disruptive upgrades and system maintenance.

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.

HPE SmartMemory technology further optimizes power usage dynamically based on workload demands, maximizing performance per watt and delivering a strong return on investment. Additionally, this module is TAA compliant, making it suitable for government and regulated industry 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, power requirements, and physical form factor.

A2: For optimal performance and stability, HPE strongly recommends populating servers with identical memory modules (same part number, capacity, speed, rank, and CAS latency). 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: Single Rank x8 (1Rx8) refers to a memory module with one independent memory bank (rank) organized in an 8-bit data width, providing a balance of performance and compatibility for mainstream workloads. EC8 Registered uses a register to buffer address and control signals, improving signal integrity and supporting larger memory configurations in enterprise servers.

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 business-critical applications.

A5: The P64705-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.
