Intel CPU Clock Ratio

Important:
• The frequency ratio of some processors may have been
locked by the manufacturer. If you are using this kind of
processor, setting an extended ratio for the processor will
have no effect. The system will instead use its factory
default ratio.
• The frequency ratio of processors greater than 8x has been
locked by the manufacturer and will no longer have the
flexibility of using extended ratios. Therefore, the system will
use the processor’s factor y default ratio.
Note:
• Use a PS/2 or AT (requires a DIN to mini DIN adapter)
keyboard for method 2.
• When using a 66MHz FSB processor with PC-100 SDRAM
DIMM, the system memor y clock is 3/2 of the CPU’s
external bus clock and the PCI clock is 1/2 of the CPU’s
external bus clock.
