P64985-K21 HPE 32GB Dual Rank Ddr5-6400MT/s Pc5-51200 Memory.

Advanced DDR5 Technology: A Leap in Server Memory Performance

DDR5 marks a revolutionary upgrade from DDR4 in terms of bandwidth, capacity scalability, and power efficiency. The HPE P64985-K21 utilizes DDR5-6400 MT/s memory architecture to support intensive workloads like virtualization, big data analytics, high-frequency trading, and real-time database processing. With an enormous bandwidth of 51.2 GB/s, it ensures swift and consistent data handling.

Increased Bandwidth and Multithreaded Efficiency

DDR5 provides double the bandwidth of DDR4, significantly boosting throughput. This module’s 6400MT/s speed is particularly useful for multi-core CPU architectures and high-demand server applications that thrive on parallelism and high memory frequency.

Enhanced Memory Channel Architecture

Each DDR5 DIMM introduces dual independent 32-bit memory channels, allowing better efficiency and parallelism in data transfers. This design facilitates more robust communication with the CPU, lowering latency and increasing per-thread performance.

Benefits for Modern Workloads

• Ideal for AI/ML workloads requiring faster data access
• Superior responsiveness in cloud-native infrastructures
• Better performance for virtual machines and containers
• Improved throughput for in-memory databases

Reliable and Secure: ECC and Smart Memory Integration

One of the standout features of the HPE P64985-K21 is its advanced ECC (Error Correction Code) capability, supported by HPE’s Smart Memory technology. ECC automatically detects and corrects single-bit memory errors, ensuring mission-critical reliability. HPE Smart Memory goes a step further by providing deeper integration with the server's firmware and hardware ecosystem, delivering optimized performance and diagnostics.

Security-Centric Architecture

HPE Smart Memory helps protect against firmware-level attacks and ensures that only authenticated and compatible modules are used within the server infrastructure, mitigating risks posed by counterfeit memory.

Power Efficiency and Lower Operating Costs

The HPE P64985-K21 operates at just 1.1V, which is significantly more efficient than earlier memory generations. This low voltage operation, combined with advanced power management integrated circuits (PMICs) on DDR5, results in reduced energy usage and less thermal output.

PMIC Benefits for Enterprise Servers

Integrated PMICs in DDR5 memory modules allow for more granular power delivery control, resulting in better energy regulation, enhanced thermal dissipation, and improved reliability under high workloads. This is essential in densely populated server racks where heat and power can become bottlenecks.

Form Factor and Compatibility

This 288-pin Registered DIMM (RDIMM) form factor ensures seamless integration with HPE server motherboards. The module is fully compatible with HPE’s latest ProLiant server families, including Gen11 and Gen10 Plus platforms. Thanks to its registered buffer design, it offloads electrical loading from the memory controller, improving stability and performance in configurations with high memory density.

Dual Rank x8 Configuration: Enhanced Signal Integrity

The dual rank x8 design allows better signal integrity and higher memory capacity support per channel. This configuration is especially effective in servers with multiple DIMMs per channel (DPC), offering a balance of speed, capacity, and error resiliency.

Use Cases for Dual Rank x8 RDIMMs

• Enterprise applications with multi-threaded compute loads
• High-performance computing (HPC) environments
• Mission-critical database servers
• Large-scale virtualization clusters
