different system functions in a user-friendly interface, which is including

Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hard-

ware Monitor, it shows the major readings of your system. In Fan Control,

it shows the fan speed and temperature for you to adjust. In Overclock-

ing, you are allowed to overclock CPU frequency for optimal system

performance. In OC DNA, you can save your OC settings as a prole

and share with your friends. Your friends then can load the OC prole to

their own system to get the same OC settings. In IES (Intelligent Energy

Saver), the voltage regulator can reduce the number of output phases to

improve efciency when the CPU cores are idle without sacricing com-

puting performance. Please visit our website for the operation procedures
