Transcend - DDR4 - module - 4 GB - SO-DIMM 260-pin - 2666 MHz / PC4-21300 -

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 mainstream notebooks. Because 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 DDR4 SO-DIMM operated at a nominal voltage of just 1.2V not only reduces heat production, but also reduces overall power consumption to save more energy.
