Built under the stringent quality standards of HPE, this Smart Memory solution provides optimal compatibility with supported HPE server platforms and is validated to meet rigorous reliability benchmarks.

DDR5 Architecture

The evolution from DDR4 to DDR5 memory marks a substantial leap in server memory performance. The HPE P76172-001 RDIMM operates at 4800MT/s, delivering significantly higher bandwidth compared to previous-generation modules. With PC5-38500 classification, this module is optimized to handle demanding enterprise applications such as virtualization, database management, cloud infrastructure, artificial intelligence workloads, and high-performance computing clusters.

4800MT/s Data Rate

Operating at 4800 megatransfers per second, this DDR5 RDIMM dramatically improves memory bandwidth. Higher data rates translate into faster data movement between the CPU and memory, reducing latency bottlenecks and improving overall system responsiveness. For organizations running memory-intensive applications, the increased throughput ensures smoother multitasking and greater computational efficiency.

PC5-38500 Bandwidth

The PC5-38500 specification indicates a theoretical peak bandwidth of 38.5GB/s per module. In multi-channel server configurations, the aggregate bandwidth increases exponentially, supporting large-scale enterprise deployments. This capability is particularly important in modern server platforms that rely on parallel processing and real-time analytics.

ECC Registered Memory

Error Correction Code (ECC) functionality is critical in enterprise environments where data integrity cannot be compromised. The HPE P76172-001 RDIMM incorporates ECC technology to detect and correct single-bit memory errors automatically, minimizing the risk of system crashes and data corruption. This feature is essential for servers operating in financial institutions, healthcare systems, research facilities, and cloud data centers.

Registered DIMM (RDIMM)

Registered memory modules use a register between the memory controller and DRAM modules to stabilize electrical signals and reduce load on the memory controller. This design enables servers to support higher memory capacities without sacrificing reliability. The RDIMM architecture ensures stable operation even when multiple modules are installed across all memory channels.

Single Rank x8

The single rank x8 configuration of the HPE P76172-001 module balances performance, compatibility, and scalability. A single rank module contains one set of DRAM chips that can be accessed simultaneously by the memory controller. The x8 organization ensures optimized data handling and compatibility with enterprise-class processors.

Performance Efficiency

Single rank memory modules often provide lower power consumption and simpler signal routing compared to dual-rank alternatives. In environments where predictable latency and stable performance are prioritized, single rank RDIMMs deliver reliable efficiency.

x8 Data Organization

The x8 configuration indicates that each DRAM chip provides an 8-bit data width. This structure supports ECC functionality and enhances data accuracy. It also ensures compatibility with server motherboards designed for enterprise DDR5 RDIMMs.

Low Voltage

Energy efficiency is a critical factor in modern data centers. The HPE P76172-001 operates at 1.1 volts, which is lower than previous DDR4 modules. Reduced voltage leads to lower power consumption, decreased heat generation, and improved energy savings across large-scale server installations.

Power Consumption

Lower voltage operation directly translates to improved energy efficiency. For data centers running hundreds or thousands of servers, even marginal reductions in per-module power usage can result in significant operational savings over time.

Compatibility

This DDR5 module uses a 288-pin RDIMM form factor designed specifically for enterprise servers. It is not compatible with standard desktop motherboards. The 288-pin configuration ensures secure installation in supported HPE server platforms, delivering optimized signal integrity and system stability.

HPE Server Platforms

As part of HPE Smart Memory solutions, the P76172-001 module undergoes extensive validation testing to ensure seamless integration with compatible HPE ProLiant servers. This validation process eliminates compatibility concerns and maximizes hardware performance.

HPE Smart Memory

HPE Smart Memory provides enhanced functionality beyond standard third-party memory modules. HPE firmware recognizes certified Smart Memory modules and enables advanced features that optimize performance and reliability.

Use Cases

The 16GB capacity makes this module suitable for entry-level to mid-range enterprise servers. It can be deployed individually or in multi-module configurations to achieve higher total memory capacities.

Virtualization Environments

In virtualized infrastructures, memory capacity directly impacts the number of virtual machines that can run efficiently. The high bandwidth of DDR5-4800 ensures that hypervisors can allocate resources dynamically without performance degradation.

Database

Database servers require consistent, low-latency memory access. The CL40 latency timing combined with DDR5 architecture provides stable responsiveness for transactional workloads and enterprise resource planning systems.

Cloud and Hybrid

Modern cloud deployments demand scalable and energy-efficient hardware components. This RDIMM module supports scalable memory configurations, allowing organizations to expand server capabilities as business needs evolve.

CAS Latency CL40

The CL40 latency rating indicates the number of clock cycles between a read command and data availability. While DDR5 introduces higher latency numbers compared to DDR4, the significantly increased clock speed offsets this difference, resulting in improved overall performance.

Balanced Latency and Speed

The combination of 4800MT/s data rate and CL40 timing provides an effective balance between throughput and response time. This ensures consistent performance across varied workloads, including analytics, virtualization, and large-scale computing operations.
