TS512MLK72W6H - Transcend 4GB DDR3-1600MHz PC3-12800 ECC Unbuffered CL11 240-Pin DIMM 1.35V Low Voltage Single Rank Memory Module

Built to exacting specifications with the finest chips and materials available, Transcend memory modules undergo strenuous laboratory testing to ensure the best performance possible. Engineered for long life and maximum durability, Transcend DDR3 ECC Low Voltage DIMMs feature Error Correcting Code (ECC) for better protection against uncorrectable errors. Operating at a nominal voltage of just 1.35V, these modules not only produce less heat, but also reduce electrical load on the memory controller to offer power savings of up to 15% versus standard 1.5V.
