HPE 128GB DDR4 3200 RDIMM ECC Server Memory

Equipment Overview

The HPE 128 GB DDR4 3200 MHz RDIMM (P11447-1A1) is a registered server memory module designed for enterprise-class servers, workstations, and storage systems. It operates as a Registered DIMM with an integrated command/address buffer, reducing electrical load on the memory controller for enhanced stability in multi-module configurations. The module incorporates ECC (Error Correction Code) Registered functionality to detect and correct single-bit errors, ensuring data integrity during continuous 24×7 operation. This memory is intended for high-availability environments requiring sustained performance under heavy transactional or virtualized workloads.

Main Parameters

• Part Number (PN): P11447-1A1
• Manufacturer: HPE
• Capacity: 128 GB
• Memory Type: DDR4
• Form Factor: RDIMM (Registered)
• Frequency: 3200 MHz
• Error Correction: ECC Registered

Key Advantages

This module is selected for enterprise projects due to its 128 GB capacity and 3200 MHz speed, which deliver high bandwidth for memory-intensive applications such as database management, virtualization, and large-scale data analytics. The registered buffering design improves signal integrity across multiple DIMMs per channel, enabling larger memory configurations without compromising stability. ECC Registered functionality provides robust error correction, making the module suitable for mission-critical systems where uncorrectable memory faults are unacceptable.

Compatibility & Integration

The HPE P11447-1A1 adheres to standard DDR4 RDIMM specifications and is compatible with HPE ProLiant servers, workstations, and storage arrays designed for 3200 MT/s registered memory. It supports industry-standard ECC Registered memory architectures and can be deployed in mixed-capacity configurations, provided the host system firmware is configured for RDIMM operation.
