Built to exacting specifications with the finest chips and components available, Transcend DDR4 SO-DIMM memory modules undergo rigorous laboratory testing to ensure unrivaled performance and stability for notebooks. Because small form-factor cases and slim notebook enclosures usually mean tightly spaced components with limited room for heat dissipation, Transcend's DDR4 SO-DIMM operates at a nominal voltage of just 1.2V to reduce heat production and overall power consumption.
