******** Clock Driving & Skew Control ******** CPU/PCIEX Clock Driving Control Allows you to adjust the amplitude of the CPU, North Bridge and PCI Express clock. Options are: 700mV, 800mV (default), 900mV, 1000mV. CPU Clock Skew Control Allows you to set the CPU clock prior to the North Bridge clock. Options are: Normal (default), 50ps~750ps. (G)MCH Clock Skew Control Allows you to set the North Bridge clock prior to the CPU clock. Options are: Normal (default), 50ps~750ps. ******** System Voltage Optimized ******** System Voltage Control Determines whether to manually set the system voltages. Auto lets BIOS automatically set the system voltages as required. Manual allows all voltage control items below to be configurable. (Default: Manual) DDR2 OverVoltage Control Allows you to set memory voltage. Normal Supplies the memory voltage as required. (Default) +0.05V ~ +1.55V Increases memory voltage by 0.05V to 1.55V at 0.05V increment. Note: Increasing memory voltage may result in damage to the memory. PCI-E OverVoltage Control Allows you to set PCIe voltage. Normal Supplies the PCIe bus voltage as required. (Default) +0.05V ~ +0.75V Increases PCIe bus voltage by 0.05V to 0.75V at 0.05V increment. FSB OverVoltage Control Allows you to set the Front Side Bus voltage. Normal Supplies the FSB voltage as required. (Default) +0.05V ~ +0.35V Increases FSB voltage by 0.05V to 0.35V at 0.05V increment. (G)MCH OverVoltage Control Allows you to set the North Bridge voltage. Normal Supplies the North Bridge voltage as required. (Default) +0.025V ~ +0.775V Increases North Bridge voltage by 0.025V to 0.775V at 0.025V increment. Loadline Calibration Lets the BIOS fine-tune the CPU Vcore voltage. Options are: Auto (default), Enabled, Disabled. CPU Voltage Control Allows you to set the CPU voltage. Normal sets the CPU voltage as required. The adjustable range is dependent on the CPU being installed.
