66/33 MHz	124/31 MHz
68/34 MHz	126/31 MHz
75/37 MHz	129/32 MHz
80/40 MHz	133/33 MHz

100/33 MHz	143/35 MHz
103/34 MHz	145/36 MHz
105/35 MHz	147/36 MHz
109/36 MHz	150/37 MHz
112/37 MHz	154/38 MHz
114/38 MHz	160/40 MHz
115/38 MHz	166/41 MHz
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 frequency of your Pentium® III & Pentium® II processor.
