Product Description
The Fujitsu S26361-F3898-L643 is a high-capacity 64 Gigabyte DDR4 Load-Reduced DIMM (LRDIMM) memory module, engineered for servers requiring maximum memory density and performance. LRDIMMs utilize a Memory Buffer (MB) chip on the module to isolate the DRAM from the memory controller. This significantly reduces the electrical load, allowing servers to support a greater number of DIMMs per channel and achieve higher total memory capacities compared to RDIMMs. Operating at 2400MHz (PC4-2400T), this module provides high bandwidth crucial for memory-intensive enterprise workloads. The 4Rx4 organization indicates a quad-rank configuration, where each rank consists of four memory chips. This advanced rank structure, combined with the load-reducing buffer, enables higher memory capacities and can improve performance through advanced interleaving techniques. With CL17 timings, the module offers standard latency for DDR4-2400MHz operation, ensuring reliable performance in demanding server environments. This Fujitsu LRDIMM is ideal for applications such as large-scale virtualization, big data analytics, and high-performance computing, where maximizing memory resources is critical for efficiency and scalability.
