The HPE P79988-001 is a 16GB DDR5-6400MT/s ECC Registered DIMM (RDIMM) Smart Memory module designed specifically for HPE ProLiant Gen11 rack and tower servers, Apollo systems, Synergy, and Blade platforms. Featuring single rank x8 architecture, PC5-51200 speed rating, and CL46 CAS latency at 1.1V operation, it delivers up to 85% higher memory performance compared to DDR4 through doubled bandwidth and density. HPE SmartMemory undergoes rigorous qualification for optimal compatibility, supporting unique features like advanced error detection, Fast Fault Tolerance for DRAM failure correction at full speed, and integration with HPE iLO for remote memory diagnostics. This enterprise-grade module enhances throughput by up to 23% and reduces latency by 25% in HPE environments, ideal for virtualization, databases, HPC, and AI/ML workloads requiring high memory capacity and reliability. The ECC functionality ensures data integrity for mission-critical applications, while low-voltage design improves power efficiency and reduces cooling costs in dense server deployments. Compatible with Intel Xeon and AMD EPYC processors in supported HPE platforms, it enables scalable memory configurations up to terabyte capacities per server.
