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 or 8.5, 9, 10,
10.5, 11, 11.5, 12. The two different tables depend on your CPU type.
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
older version CPUs.
