Transcend DDR3L 1600 LONG-DIMM 4GB CL11 1Rx8 1.35V - 4 GB (1 x 4GB) - DDR3-1600/PC3-12800 DDR3 SDRAM - 1600 MHz - CL11 - 1.35 V - - - (TS512MLK64W6H)

Built to exacting specifications with the finest chips and materials available, Transcend memory modules undergo strenuous laboratory testing to ensure the best performance possible. Transcend DDR3 Low Voltage DIMMs operate at a nominal voltage of just 1.35V, which not only produces less heat, but also reduces electrical load on the memory controller to offer power savings of up to 15% versus standard 1.5V.
