Under this item you find the
frequencies your PCI slots run
at.
(2) 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 equal the working frequency of your CPU.
(3) DRAM Clock
(3) DRAM Clock
Now select the DRAM clock source. It is derived form the CPU FSB
clock and it can, depending on the BIOS setting, be:
Ø
Equal to the CPU FSB clock
Ø
CPU FSB clock – PCI clock
Ø
CPU FSB clock + PCI clock
As an example: If the user sets the CPU Host/PCI clock to 105/35 MHz,
the options will be:
Ø
Equal to the CPU FSB clock = 105 MHz
Ø
CPU FSB clock – PCI clock = 70 MHz
Ø
CPU FSB clock + PCI clock = 140 MHz
