The FUJITSU S26361-F3604-E513 memory module offers a compact yet potent upgrade for older generation servers, with a capacity of 2GB and a speed of 1333MHz. It utilizes DDR3 technology, which stands for third-generation Double Data Rate memory, providing a balance between performance and power consumption. The '1Rx4' configuration indicates a single-rank module with four data banks, optimized for compatibility and stability in a wide range of systems. This particular module operates with a PC3-10600R specification, ensuring data transfer rates that can achieve up to 10666MB/s, making it ideal for enhancing the performance of entry-level servers and workstations that require DDR3 type memory. Being a Registered (buffered) DIMM, it features additional hardware to improve signal integrity and maintain system stability by minimizing electrical load on the memory controller. This makes it particularly suitable for systems that need to maintain uptime and reliability. Engineered to fulfill the needs of Fujitsu's server platforms, this memory module is a cost-effective way to extend the life and improve the performance of older infrastructure.
