9.ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to ne-tune dif- 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 profile and share it with your friends. Your friends then can load the OC profile 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 efficiency when the CPU cores are idle without sacrificing com- puting performance. Please visit our website for the operation procedures of ASRock Extreme Tuning Utility (AXTU).
