HPE 128GB 4DRx4 DDR4-3200-L PC4-25600 LRDIMM ECC Load-Reduce Memory Samsung M386AAG40AM3-CWE P11447-1A1 P20505-001 P07652-B21

Upgrade your enterprise server infrastructure with the HPE 128GB 4DRx4 DDR4-3200-L PC4-25600 LRDIMM ECC Load-Reduce Memory Samsung M386AAG40AM3-CWE P11447-1A1 P20505-001 P07652-B21. Designed for demanding data center, virtualization, cloud, and high-performance computing environments, this high-capacity memory module delivers exceptional reliability, scalability, and performance for mission-critical workloads.

Built by Samsung and qualified for HPE server platforms, this 128GB Load-Reduced DIMM (LRDIMM) helps maximize memory capacity while maintaining signal integrity across large memory configurations. Operating at DDR4-3200 speeds, it provides fast data transfer rates and enhanced bandwidth, helping improve system responsiveness for memory-intensive applications such as database management, analytics, virtualization, and enterprise workloads.

Featuring ECC (Error-Correcting Code) technology, this module actively detects and corrects memory errors, reducing the risk of data corruption and improving server stability. The quad-rank (4DRx4 / 4Rx4) architecture and load-reduced design enable greater memory density compared to traditional RDIMMs, making it an ideal choice for modern HPE servers and workstations that require large memory footprints.
