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.
