S4J68A HPE 128GB DDR5-5600 288-Pin RDIMM Memory Module

S4J68A Overview

The HPE S4J68A is a 128GB DDR5 Registered DIMM (RDIMM) designed for HPE ProLiant Gen11 servers, delivering 5600MT/s speed for high-bandwidth, low-latency performance in enterprise and data center workloads. Its 288-pin architecture supports DDR5 technology, providing enhanced throughput, improved efficiency, and scalability compared to DDR4 modules.Equipped with ECC (Error-Correcting Code), this module ensures data integrity and system reliability by detecting and correcting memory errors, which is critical for mission-critical applications and always-on enterprise environments. The registered (buffered) design reduces electrical load on the memory controller, enabling higher memory density and stable operation in multi-DIMM server deployments.
