ASUS EPU-6 Engine is an energy-efcient tool that satises different computing
needs. This utility provides four modes that you can select to enhance system
performance or save power. Selecting Auto mode will have the system shift modes
automatically according to current system status. You can also customize each
mode by conguring settings like CPU frequency, vCore Voltage, and Fan Control.
