Under this item you find the
frequencies your PCI and
AGP slots run at. These
frequencies are derived
from the CPU host clock in
the following way:
CPU host clock > 100MHz
PCI = CPU host clock /3,
CPU host clock < 100MHz
PCI = CPU host clock /2,
(b) CPU Ratio
After you have selected the CPU Host/ PCI Clock, choose the right
multiplier for the CPU. CPU Ratio options are:
o x 2 o x 2.5 o x 3 o x 3.5 o x 4
o x 4.5 o x 5 o x 5.5 o x 6 o x 6.5
o x 7 o x 7.5 o x 8
The CPU frequency is then defined as [host clock freq.] x [multiplier],
and should the working frequency of your CPUs processor.
(c) 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 100MHz,
[Auto] sets
à
When [auto] is selected and the (FSB Frequency) is
less then 100MHz, it will be divided by [/ 1]. Otherwise it will
be divided by [/ 1.5].
[/ 1] sets
à
AGP Clock = 100MHz
[/ 1.5] sets à AGP Clock = 66.6MHz
AGP Clock options are:
o Auto
o ÷1.0
o÷1.5
