CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being used. CPU Host Clock Control Enables or disables the control of CPU host clock. Auto (default) allows BIOS to automatically adjust the CPU host frequency. Manual allows the CPU Frequency (Mhz) item below to be configurable. Note: If your system fails to boot after overclocking, please wait for 20 seconds to allow for automated system reboot, or clear the CMOS values to reset the board to default values. CPU Frequency (MHz) Allows you to manually set the CPU host frequency. The adjustable range is from 200 MHz to 500 MHz. Important It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. 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: Auto) 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. (Default: Normal) Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU. Normal CPU Vcore Displays the normal operating voltage of your CPU. DDR2 Voltage Control Allows you to to set memory voltage. Normal Supplies the memory voltage as required. (Default) +0.025V ~ +0.375V Increases memory voltage by 0.025V to 0.375V at 0.025V increment. NorthBridge Volt Control Allows you to to set North Bridge voltage. Normal Supplies the North Bridge voltage as required. (Default) +0.025V ~ +0.375V Increases North Bridge voltage by 0.025V to 0.375V at 0.025V increment. SouthBridge Volt Control Allows you to to set South Bridge voltage. Normal Supplies the South Bridge voltage as required. (Default) +0.025V ~ +0.375V Increases South Bridge voltage by 0.025V to 0.375V at 0.025V increment. - 53 - BIOS Setup
