Additional Details

The HMT31GR7EFR4A-H9 is a 240-pin DDR3 RDIMM (Registered Dual In-Line Memory Module) designed for use in servers and high-performance workstations. The ECC (Error-Correcting Code) functionality is crucial for server applications as it automatically detects and corrects single-bit memory errors, which can be critical in maintaining system stability and preventing data loss. The registered design includes a register between the DRAM modules and the system's memory controller, which helps to improve signal integrity and allows for greater memory capacity. The 1600MHz speed (PC3-12800) refers to the module's data transfer rate, which indicates how quickly the module can transfer data to and from the system. The 1Rx4 configuration signifies that the module is a single-rank module with a x4 organization, meaning it uses four data lines per rank. Operating at 1.35V contributes to lower power consumption and reduced heat generation, making it an energy-efficient choice for servers that require continuous operation.
