The wrong settings of the multiplier and external clock in certain circumstances may
cause CPU damage. Setting the working frequency higher than the PCI chipset or
processor specs, may cause abnormal memory module functioning, system hangs, hard
disk drive data lose, abnormal functioning of the VGA card, or abnormal functioning
with other add-on cards. Using non-specification settings for your CPU is not the
intention of this explanation. These should be used for engineering testing, not for
normal applications.
If you use non-specification settings for normal operation, your system may not be
stable, and may effect system reliability. Also, we do not guarantee the stability and
compatibility for settings that are not within specification, and any damage of any
elements on the motherboard or peripherals, is not our responsibility.

How is each component's working frequency calculated? For starters, everything is
derived from the clock generator on the motherboard. Upon boot up the CPU will
give the clock generator the default value for the Front Side Bus (FSB). Once the
