DDR3-1333 ECC-DIMMs are specially engineered to maintain optimum performance even in extreme hot or cold environments. Moreover, Transcend's Industrial Grade Temp DDR3-1333 ECC-DIMM features Error Correcting Code that monitors the data that gets transferred in and out of memory and corrects any errors found. This greatly decreases the risk of computational errors during complex tasks, while at the same time increases overall system reliability.
