Transcend's DDR4 SO-DIMM memory modules are manufactured to demanding specifications using the highest quality chips and components available on the market and undergo rigorous lab testing to ensure unmatched performance and stability for mainstream notebooks. Since small form factor cases and slim notebook designs typically feature closely spaced components that offer limited space for heat dissipation, Transcend's DDR4 SO-DIMM, which operates at a nominal voltage of just 1.2 V, not only reduces heat generation but also lowers overall power consumption to save more energy.
