P43336-6A1 HPE 128GB DDR5-4800MT/s PC5-38400 ECC RDIMM Memory Module

P43336-6A1 Overview

The HPE P43336-6A1 is a 128GB DDR5 Registered DIMM (RDIMM) designed for HPE ProLiant Gen11 servers, delivering 4800MT/s speed (PC5-38400) to provide high memory bandwidth and low latency for enterprise workloads. With its 288-pin form factor, it supports DDR5 technology, enabling greater performance, scalability, and efficiency compared to DDR4 modules.Equipped with ECC (Error-Correcting Code), the module ensures data integrity and system reliability, actively detecting and correcting memory errors, which is critical for mission-critical applications and always-on enterprise environments. Its registered (buffered) design reduces electrical load on the memory controller, allowing higher memory density and stability in multi-DIMM server deployments.Part of HPE’s SmartMemory ecosystem, the P43336-6A1 is fully validated for compatibility, performance, and reliability on HPE platforms.
