Transcend TS512MLK72W6H RAM Module - DDR3L 1600 ECC DIMM 4GB CL11 1Rx8 1.35V 4 GB (1 x 4GB) DDR3 1600/PC3 12800 DDR3 SDRAM 1600 MHz CL11 1.35 V ECC Unbuffered 240 pin DIMM

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.
