Overclocking a CPU is at your own risk. It may permanently damage your
CPU and void your warranty.
Changing “CPU to PCI Divider”.
Once the frequency of the CPU is changed, the next (most important) thing
to do is to change the “CPU to PCI Divider”. The purpose of the divider is to
allow the PCI bus to run at the standard “33MHz” or close to the standard
PCI bus speed. Here is the table to show the recommended divider to pick
associate with the frequency.

From the table it provide the desire PCI bus ranging from 30 ~ 40 MHz. The
most safe range is between 30 ~ 37.5 MHz.
