The FUJITSU M393B2G70QH0-CMA-FU memory module comes with a capacity of 16GB, offering substantial room for multitasking and large-scale computing tasks. This DDR3 module operates at a frequency of 1866MHz, under the PC3-14900R classification, delivering high-rate data transfer speeds essential for server applications and data-intensive programs. The 2Rx4 configuration indicates a dual-rank setup with four data banks, optimized for high-density and stability in demanding operational environments. Featuring Registered (Buffered) memory, it includes a register between the DRAM modules and the system's memory controller, enhancing stability and reliability in systems by reducing electrical loads. This is particularly beneficial in servers and high-end workstations, wherein ECC (Error-Correcting Code) support provides an additional layer of data integrity, automatically identifying and correcting any data corruption. This makes the module an excellent choice for enterprise-level hardware that requires robust, error-free performance. Its DDR3 technology, while being a previous generation compared to DDR4, still offers compelling performance for systems not yet transitioned to newer memory standards.
