Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately alter ing the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.) • When the System Voltage Optimized item blinks in red, it is recommended that you set the System Voltage Control item to Auto to optimize the system voltage settings. 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 NorthBridge Freq. (Note) Allows you to alter the North Bridge controller frequency 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. (Note) This item is present only if you install a CPU that supports this feature. - 39 - BIOS Setup
