3.10 Frequency / Voltage Control

CPU Host / PCI Clock
This function allows you to set the FSB frequency of the CPU and the speed of PCI
bus. When JP3 is set to 66MHz, you can select the system bus frequency from 66MHz
to 68 MHz. When JP3 is set to 100MHz, you can select the system bus frequency from
100MHz to 124MHz. When JP3 is set to 133MHz, you can select the system bus frequency
from 133MHz to 150MHz.
•
CPU Ratio
This function allows you to set the CPU internal frequency ratio. It determines the CPU
internal frequency according to the following formula:
CPU internal frequency = frequency ratio x system bus frequency.*
* System bus frequency is set in the previous field (“CPU Host / PCI Clock”).
The choices: “3”, “3.5”, “4”, “4.5”, “5”, “5.5”, “6”, “6.5”, “7”, “7.5”, and “8”.
NOTE: Because Intel has locked the frequency ratio for new CPU settings, this field
to adjust the frequency ratio is usually useless. However, it is effective for old version
CPUs.
