P64705-B21 Overview

The HPE P64705-B21 is a 16GB DDR5 Registered DIMM (RDIMM) designed for HPE servers and enterprise workloads that demand reliability, speed, and efficiency. Running at 5600MT/s (PC5-44800), it delivers significantly higher bandwidth compared to DDR4, ensuring smooth performance for modern applications such as virtualization, big data analytics, AI/ML, and cloud computing.
With ECC (Error-Correcting Code) support, this memory module automatically detects and corrects memory errors, improving system stability and uptime in mission-critical environments. The 1Rx8 single-rank design, CL46 latency, and 288-pin RDIMM form factor provide balanced performance and compatibility with HPE ProLiant Gen11 servers and other supported platforms. Operating at just 1.1V, it ensures energy-efficient performance while maintaining enterprise-grade reliability.
