Transcend TS512MSK64W6N - 4GB DDR3L 1600 So-DIMM 2RX8

Small form-factor cases and slim notebook enclosures usually come hand-in-hand with tightly spaced components with limited room for heat dissipation. Transcend's DDR3 Low Voltage SO-DIMM operates at a nominal voltage of just 1.35V which not only reduces heat production but also reduces overall power consumption for compact low power mini-ITX systems and slim power-efficient notebooks.
