ferent system functions in a user-friendly interface, which includes Hard-
ware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hardware
Monitor, it shows the major readings of your system. In Fan Control, it
shows the fan speed and temperature for you to adjust. In Overclocking,
you are allowed to overclock CPU frequency for optimal system per-
formance. In OC DNA, you can save your OC settings as a pro
fi
le and
share it with your friends. Your friends then can load the OC pro
fi
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
fi
ciency when the CPU cores are idle without sacri
fi
cing com-
puting performance. Please visit our website for the operation procedures
