CPU Ratio
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 &
Celeron

processor.

/ 1.5
AGP Clock
This option allows you to manually adjust the
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
Normal Default
+2.5 %
+5.0%
+7.5 %
Vcore voltage
Adjust
+10.0%
The CPU notifies the board of what core
voltage it requires by its VID outputs. The
on-board voltage regulator uses the VID
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.
