Auto Detect DIMM/
PCI Clk
When this item is enabled, BIOS will disabled the
clock signal of free DIMM and PCI slots.
Spread Spectrum
Eables or disables the spread spectrum for the
installed processor.
CPU Host/PCI
Clock
This item appears if you have set the
CPU Internal
Core Speed
to Manual. Use the
CPU/DIMM/PCI
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)
.
