• CPU Clock 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 are: “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.
