CPU Host/

 

 

 

 

 

 

Default

110/37MHz/NO

Select the host clock of your

 

PCI Clock

 

66/33MHz/NO

115/38MHz/NO

Socket 370 processor among these

 

 

 

68/35MHz/NO

133/33MHz/Yes

values.

 

 

 

 

 

Note: For the 815 chipset, 66,

 

 

 

70/35MHz/NO

137/34MHz/Yes

 

 

100 and 133 MHz host clock

 

 

 

75/38MHz/NO

140/35MHz/Yes

 

 

frequencies are acceptable.

 

 

 

80/40MHz/NO

145/36MHz/Yes

However, the system stability

 

 

 

83/42MHz/NO

150/37MHz/Yes

is not guaranteed for other

 

 

 

100/33MHz/NO

160/38MHz/Yes

frequencies due to the

 

 

 

 

 

limitations of this chipset.

 

 

 

103/34MHz/NO

166/42MHz/Yes

 

 

 

 

 

 

105/35MHz/NO

 

 

 

 

 

 

 

 

 

CPU Clock Ratio

After you have selected the host clock, choose the right multiplier for the CPU. Options are: [ 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 & Celeronprocessor.
