HPE P75958-001 256GB Memory Overview

The HPE P75958-001 256GB Quad Rank X4 DDR5-6400MHz PC5-51200 CL60 1.1V Registered 288-Pin Smart Memory represents the latest generation of enterprise-class memory technology designed specifically for high-performance server infrastructures. Built to meet the rigorous demands of modern data centers, virtualization clusters, AI-driven workloads, and mission-critical applications, this DDR5 Registered Smart Memory module combines extreme capacity, high bandwidth, and intelligent reliability features into a single enterprise-grade solution. As organizations scale their IT environments, the demand for faster memory with larger capacities continues to grow, and this 256GB DDR5 module delivers exactly that in a robust, validated HPE-certified configuration.

DDR5-6400MHz Performance

At the core of this memory module is DDR5-6400MHz speed, offering a significant performance leap compared to previous DDR4 generations. Operating at 6400MT/s, this PC5-51200 module provides up to 51.2GB/s of theoretical bandwidth per DIMM, dramatically increasing data throughput for memory-intensive workloads. This enhanced bandwidth enables enterprise servers to handle complex database queries, large-scale virtualization environments, real-time analytics, and high-performance computing tasks with reduced latency and improved responsiveness.

Advantages of DDR5

DDR5 introduces architectural improvements that go far beyond higher clock speeds. The module integrates on-die ECC for improved data integrity, dual independent 32-bit subchannels per DIMM for increased efficiency, and improved burst length for optimized data transfers. These enhancements allow systems using the HPE P75958-001 memory to achieve greater parallelism, reduced bottlenecks, and more consistent performance under heavy workloads.

Enhanced Data Throughput

Modern enterprise workloads such as large-scale ERP systems, in-memory databases, machine learning training models, and virtualization hosts require enormous memory bandwidth. With PC5-51200 classification, this DDR5 module ensures servers can maintain consistent throughput under peak load conditions, minimizing application slowdowns and improving user experience across enterprise networks.

256GB High-Capacity

The 256GB capacity of the HPE P75958-001 memory module enables exceptional scalability for enterprise servers. High-capacity DIMMs reduce the total number of slots required to reach large memory footprints, improving airflow, energy efficiency, and overall system design flexibility. Quad Rank architecture allows for optimized density while maintaining stability in multi-socket server configurations.

Quad Rank Memory

Quad Rank memory organizes memory chips into four logical ranks, allowing for greater density within a single module. This design increases total memory capacity per DIMM while maintaining compatibility with enterprise server memory controllers. For organizations deploying high-memory servers for virtualization clusters or database servers, quad rank modules enable scaling to multiple terabytes of memory across supported platforms.

Registered DIMM

As a Registered DIMM, the HPE P75958-001 integrates a register between the DRAM modules and the memory controller. This buffering mechanism reduces electrical load on the memory controller, allowing servers to support higher capacities and more DIMMs per channel without compromising stability. RDIMM technology is essential for enterprise-class servers where performance consistency and reliability are critical.

Improved Signal Integrity

Registered memory enhances signal integrity by re-driving command and address signals, minimizing noise and electrical interference. This ensures stable operation even in multi-DIMM per channel configurations commonly found in high-density rack servers and blade systems.

Optimized for Multi-Socket

Enterprise servers often utilize dual-socket or quad-socket processor configurations. Registered DDR5 modules like the HPE P75958-001 are engineered to operate efficiently in these multi-CPU systems, supporting balanced memory distribution and ensuring maximum memory bandwidth utilization across all processor cores.

HPE Smart Memory

The Smart Memory designation distinguishes HPE-certified memory modules from generic alternatives. HPE Smart Memory undergoes rigorous qualification and validation processes to ensure compatibility, performance optimization, and firmware-level integration with HPE servers. This guarantees seamless deployment and reduces the risk of memory-related issues.

CL60 Latency

With a CAS Latency of CL60, the HPE P75958-001 memory module is optimized for high-frequency DDR5 operation. While higher frequencies naturally introduce latency considerations, DDR5 architecture improvements compensate through parallel subchannels and increased burst lengths, resulting in overall improved effective performance for enterprise workloads.

Compatibility

The HPE P75958-001 256GB DDR5 Registered Smart Memory module is designed for compatibility with next-generation HPE enterprise servers that support DDR5 RDIMM technology. These include platforms powered by the latest Intel and AMD server processors that leverage DDR5 memory controllers for enhanced performance and scalability.

HPE ProLiant Gen11

This memory module is optimized for use in servers such as the HPE ProLiant Gen11 series, ensuring seamless integration, validated performance, and maximum reliability. By deploying HPE-certified memory, organizations protect their infrastructure investment and maintain warranty compliance.
