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 profi le  and 
share it with your friends. Your friends then can load the OC profi 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 effi ciency when the CPU cores are idle without sacrifi cing

computing performance. Please visit our website for the operation proce-
dures of ASRock Extreme Tuning Utility (AXTU).
