550MHz (100 x 5.5)
Select the working
frequency of your
Pentium
®
 II processor
among these preset
values.
Note: Setting this field to
[Manual] requires you to
fill in the next two
consecutive fields:
(1) the [CPU Host Clock],
(2) the [CPU Ratio].
If [CPU Speed] field is set to [Manual]
68 MHz
75 MHz
83 MHz
66 MHz
103 MHz
112 MHz
133 MHz
CPU Host Clock
100 MHz
Select the host clock of your Pentium
®
II processor among these values.
Note: For the EX/LX chipset,
66MHz and 100MHz host clock
frequencies are acceptable.
However, the system stability is
not guaranteed for other
frequencies due to the limitations
of this chipset.
If [CPU Speed] field is set to [Manual]
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]. The CPU frequency is then
defined as [host clock freq.]x[multiplier], and should
match the working frequency of your Pentium
®
 II
processor.
