- 51 - BIOS Setup
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: Manual)
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 set the 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 set the 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.
