118/39 MHz
Select the host clock of your
Slot 1 processor among these
values.
Note: For the Via 694X
chipset, 66 and 100 and
133 MHz host clock
frequencies are acceptable.
However, the system
stability is not guaranteed
for other frequencies due
to the limitations of this
chipset.
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
