Introduction

5-4 POWER BIOS Features

This page lets you adjust various parameters to obtain improved performance for overclocking.
Overclocking requires expert knowledge and risks permanent damage to system components.
We recommend you leave these parameters at their default values for proper operation.
Auto Detect PCI Clk
When enabled the mainboard automatically disables the clock source for a PCI slot which does not have a module in it,
reducing EMI (ElectroMagnetic Interference).
Options: Enabled, Disabled.
Spread Spectrum Modulated
If you enable spread spectrum, it can significantly reduce the EMI (ElectroMagnetic Interference) generated by the
system.
Options: Enabled, Disabled.
Watch Dog Function
If you select "Enabled" and overclock fail before POST code 26h, the system will reset automatically by default configuration.
Options: Enabled, Disabled.
CPU CLOCK/SPEED
Enables you to increment the CPU's clock generator at 1 MHz step. This works together with CPU Clock Ratio (below)
to set the CPU operating frequency.
CPU Clock Generator x CPU Clock Ratio = CPU Frequency
For example, if you have a processor that is rated at 2.4GHz and the clock generator is 200MHz, then 200MHz x 12
= 2.4GHz

Overclocking failure will cause no display on the monitor. To overcome this switch off the power supply
and switch on again. Restart the system, press and hold < Insert> key. This will revert the BIOS to
default or initial setting. Refer to Hotkey summary at the end of this manual.
