P50312-B21 HPE 64GB dual rank memory DDR5-4800 EC8 Registered Smart Memory Kit

The P50312-B21 is a 64GB enterprise-grade DDR5 Registered Smart Memory Kit (RDIMM) engineered by Hewlett Packard Enterprise (HPE) for mission-critical server environments. Delivered as a single 64GB module, it features a 4800 MT/s data rate, Dual Rank x4 chip organization, CAS latency of 40-39-39, and EC8 error correction, making it ideal for HPE ProLiant Gen11 servers running virtualization, large databases, cloud workloads, and high-performance computing.

As HPE SmartMemory, it undergoes rigorous qualification and testing to unlock performance features exclusive to HPE platforms, ensuring optimal compatibility, stability, and reliability in 24/7 data center operations.

Built with DDR5 technology, this memory kit delivers significant bandwidth improvements over DDR4 while operating at a low 1.1V voltage for enhanced power efficiency. The Registered (RDIMM) design buffers address and control signals to support larger memory configurations, while EC8 provides advanced error correction to protect data integrity. The Dual Rank x4 architecture balances performance and capacity, making it suitable for memory-intensive enterprise applications.

The P50312-B21 operates at a native speed of 4800 MT/s (PC5-38400), delivering high throughput to handle data-intensive tasks such as virtual machine (VM) density, in-memory databases, and real-time analytics. With a CAS latency of 40-39-39, it provides responsive data access, minimizing latency for critical applications.

The DDR5 architecture includes on-die error correction (ECC) and EC8, offering robust data protection against soft errors and enhancing system stability in long-running environments. HPE SmartMemory undergoes extensive testing, including signal integrity validation, thermal stress testing, and compatibility verification with HPE ProLiant servers.

The 1.1V low-voltage design reduces power consumption and heat generation, improving cooling efficiency and extending component lifespan. The Dual Rank x4 configuration optimizes memory bandwidth and capacity, supporting scalable performance for growing enterprise demands.

This memory kit is fully compatible with HPE ProLiant Gen11 rack, tower, and blade servers, as well as HPE Synergy systems. It supports both AMD and Intel-based Gen11 platforms, providing broad flexibility for server deployments. The 288-pin DIMM form factor adheres to industry standards, ensuring easy installation in standard server memory slots.

As HPE SmartMemory, it includes advanced features such as firmware-level integration with HPE servers, enabling real-time health monitoring, performance tuning, and automatic error recovery. This integration unlocks full memory performance potential and ensures seamless interoperability with HPE's system management tools.

It is designed for HPE ProLiant Gen11 rack, tower, and blade servers, as well as HPE Synergy systems, supporting both AMD and Intel-based platforms.

HPE SmartMemory undergoes rigorous testing for HPE servers, unlocking exclusive performance features, enabling real-time health monitoring, and ensuring optimal compatibility and reliability.

EC8 is an enhanced error correction code that provides advanced data protection, correcting more memory errors than standard ECC to improve system stability.

While it uses industry-standard DDR5 RDIMM specifications, full functionality and HPE SmartMemory features are only guaranteed on HPE Gen11 servers.

Hot-swap support depends on the specific HPE server model; consult your server's documentation for memory hot-plug capabilities.
