The FUJITSU S26361-F3781-E515 represents a robust and reliable memory solution for Fujitsu server platforms requiring the DDR3 technology standard. With an 8GB capacity and a 1600MHz clock speed, this module delivers the balance of performance and power efficiency needed in modern data centers and enterprise computing environments. The PC3L-12800R specification indicates both the performance level and the use of Low Voltage (LV) technology, which reduces the module's power consumption compared to standard DDR3 memory, contributing to a lower overall energy cost for running servers. This Registered DIMM (RDIMM) module is designed to offer stability and reliability for critical server applications through its 1Rx4 configuration, meaning it has one rank and uses x4 organization. The ECC (Error-Correcting Code) feature is a significant advantage, offering the ability to detect and correct data corruption in real-time, a necessity in environments where data integrity is crucial. As an RDIMM, it also facilitates higher memory densities and stability for the system by buffering the address, control, and clock lines, which is essential for servers that require large memory configurations. The S26361-F3781-E515 module provides a straightforward upgrade path, enhancing the performance and reliability of Fujitsu servers that support DDR3 memory technology.
