Eables or disables the spread spectrum for the
installed processor.
CPU Host/PCI
This item appears if you have set the CPU Internal
Core Speed to Manual. Use the CPU/DIMM/PCI
Clock
Clock to set the frontside bus frequency for the
installed processor (usually 133 MHz, 100 MHz or
66 MHz). Then use CPU Clock Ratio to set a
multiple.
CPU Clock Ratio
Use this item to select a multiplier for the system
frontside bus (FSB) frequency. The value of the
multiplier must be set so that:
Multiplier x Frontside Bus Frequency = CPU Clock
Speed
For example, if you have a processor that is rated
to run at 450 MHz and the system is running a
frontside bus frequency of 100 MHz, you should
select a multiplier of 4.5 so that:
4.5 (Multiplier) x 100 MHz (frontside bus) = 450
MHz (CPU clock).
