Additional Details

The module utilizes a 240-pin DIMM form factor, which is standard for DDR2 memory. The ECC (Error-Correcting Code) feature ensures data integrity by detecting and correcting single-bit errors. This is particularly crucial in server and workstation environments where data corruption can have significant consequences. The Registered design incorporates a register between the DRAM chips and the memory controller, which buffers the signals and reduces the electrical load on the memory controller. This allows for greater system stability and the use of more memory modules. The Serial Presence Detect (SPD) feature allows the BIOS to automatically configure the memory module settings for optimal performance. DDR2 memory operates at a lower voltage than DDR, resulting in reduced power consumption. The HYS72T256420HFN-3S-B is designed to meet the stringent requirements of enterprise computing environments.
