Overclocking Calculator calculates CPU speeds, PCI bus speed, and the
AGP bus speed based on the information it is given to work with.
For instance, if your FSB (Front Side Bus) is set to 100 mhz, and your CPU multiplier is set to 8, your CPU will be
running at 800 mhz. It will also tell you what your PCI bus speed will
be if you set the PCI multiplier to 1/2, 1/3, 1/4 or any other setting
at any range of bus speeds. It will also give you the same type of
information for the AGP bus.
