	Users can enjoy a fully interactive 3D utility that facilitates adjustment of the 3 dimensions that control the power delivery to your CPU and Memory: Voltage, Phase and Frequency. These parameters are crucial to how the digital PWM supplies power to critical areas of the motherboard and can help users quickly obtain the highest, most stable overclock.
	3D Power: Voltage Control Voltage parameters can be modified within 3D Power, including load line calibration of the CPU. By adjusting load line calibration, Vdroop can be avoided, maintaining optimal voltages levels despite increasing current levels. OVP (over voltage protection) can also be adjusted to change default protection range of the CPU, IGP, VTT and system memory.
	3D Power: Phase Control Users can calibrate OCP (Over Current Protection) for the CPU, integrated memory controller and system memory power levels. This allows the Phase control to deliver even more power to the system when needed.
	3D Power: Frequency Control GIGABYTE's all digital PWM allows for adjustable frequency control via the International Rectifier PWM controller. 3D Power frequency control allows users to change the PWM controller frequency so that the CPU VRM can adjust power delivery speeds more quickly. Users can also adjust the PWM spectrum or maximum and minimum overall frequencies.
