P71256-001 HPE 64GB Dual Rank Ddr5-6400mt/s Pc5-51200 Memory.

Understanding DDR5 Registered Memory

DDR5 (Double Data Rate 5) memory is the latest evolution in DRAM technology. Registered DIMMs (RDIMMs), like the HPE P71256-001, are purpose-built for servers and workstations, where stability, capacity, and reliability are of utmost importance. Registered memory includes a register or buffer between the memory controller and the DRAM modules to reduce electrical load and improve signal integrity, enabling servers to scale to higher capacities and faster speeds.

What Makes DDR5 a Game-Changer

• Increased Bandwidth: DDR5 offers significantly higher data transfer rates compared to DDR4. The 6400MT/s speed on this module ensures fast data access and reduced bottlenecks.
• Greater Capacity: DDR5 supports higher density chips, allowing more memory per module and paving the way for up to 128GB and beyond per DIMM in future generations.
• Improved Power Efficiency: Integrated power management and lower operating voltages (1.1V standard) reduce power draw and thermal output.
• On-die ECC: Built-in error correction increases reliability, reducing system crashes due to memory errors.

Features of the HPE P71256-001 64GB Smart Memory Module

This high-capacity 64GB module is built with advanced Smart Memory features, specifically optimized for HPE ProLiant servers. Let’s explore the detailed features that make this component a staple for enterprise-level computing:

Dual Rank X4 Organization

The dual rank (2R) design utilizes two sets of DRAM chips for enhanced memory access efficiency. The X4 configuration implies that each chip contributes 4 bits per data word, increasing reliability through advanced error correction and allowing high memory density.

PC5-51200 Bandwidth

With a rated bandwidth of PC5-51200, this memory module can transfer up to 51.2 GB/s. This is ideal for large-scale data workloads, virtual environments, high-performance computing (HPC), and big data analytics.

CL46 Latency

CAS Latency (CL) of 46 strikes a balance between speed and stability, ensuring data is accessed swiftly while maintaining high integrity in performance-intensive operations.

288-Pin DIMM Interface

The 288-pin interface ensures compatibility with the latest server motherboards and platforms that support DDR5 memory. Enhanced electrical and mechanical specifications support stable operation at high speeds.

Registered DIMM (RDIMM) Architecture

The RDIMM structure buffers command and control signals, allowing more DIMMs per channel and significantly improving memory scalability—critical for database servers and virtualized environments.

Smart Memory Support for HPE Ecosystem

HPE Smart Memory is validated, tuned, and tested for compatibility and reliability within the HPE infrastructure. This ensures optimized performance, firmware integration, and diagnostic support through HPE’s iLO (Integrated Lights Out) management.
