Frequency Setup

 

 

 

 

 

 

 

 

 

 

 

If [CPU Frequency] field is set to [Manual]

After you have selected the host clock, choose the right multiplier for the CPU. Options are: [2, 2.5, 3., 3.5, 4, 4.5, 5, 5.5,6,6.5,7.0,7.5,8.0]. The CPU frequency is then defined as [host clock freq.]x[multiplier], and should the working frequency of your Pentium® III, Pentium® II & Celeronprocessor.

AGP Clock

 

 

 

 

 

Auto

 

 

Default

 

 

/ 1

This option allows you to manually adjust the

 

 

/ 1.5

AGP host bus clock frequency to a value

 

 

 

determined as a fraction of the CPU host clock.

 

 

 

For example:

 

 

 

 

 

With a CPU front side bus of 66MHz,

 

 

 

[/ 1] sets à

AGP Clock = 66MHz

 

 

 

[ / 1.5] sets à AGP Clock = 44MHz

 

Vcore voltage

 

 

 

 

 

Normal

 

 

Default

 

Adjust

+2.5 %

The CPU notifies the board of what core

 

 

+5.0%

voltage it requires by its VID outputs. The

 

 

+7.5 %

on-board voltage regulator uses the VID

 

 

+10.0%

code to set the core voltage. If the Vcore

 

 

 

Voltage adjust is set to normal, the Vcore

 

 

 

will be exactly what the VID code

 

 

 

specifies. If an adjustment percentage is

 

 

 

selected the Vcore will be that percentage

 

 

 

higher than the VID code specifies. If for

 

 

 

instance the VID code specifies 2.0V and

 

 

 

the Vcore Voltage Adjust is set to +10.0%

 

 

 

the actual CPU voltage will be 2.2V. This

 

 

 

function should only be used if the CPU is

 

 

 

running on FSB Frequencies beyond the

 

 

 

CPu specifications.
