DDR3 XR-DIMM is Innodisk's most robust memory module - perfect for critical-mission applications and harsh environments. Furthermore, both ECC and Wide Temperature ( -40ºC to 85ºC) features are available to further optimize the module if needed. With its 300-pin socket connector, Innodisk’s XR-DIMM exceeds the pin number standard established by the SFF Special Interest Group (SFF-SIG), ensuring a firm connection between the CPU and DRAM module. The series includes 4GB and 8GB capacities and transfer rates of 1600 MT/s and 1866 MT/s.

ECC modules are designed to detect and correct single-bit errors that occur during data storage and transmission. ECC modules use Hamming Code or Triple Modular Redundancy for error detection and correction, and manage error corrections on their own, without requesting that the data source resend original data.
