Frequency/Voltage Control
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)
Auto Detect PCI/DIMM Clk
When this item is enabled, BIOS disables the clock signal of free DIMM
and PCI slots.
Ø
The choice: Enabled, or Disabled.
Spread Spectrum
This item allows you to enable/disable the spread spectrum modulation.
Ø
The choice: Disabled, Sp/- 0.5%, Sp/- 0.3%.
CPU Host/AGP/PCI clock
Use the CPU host clock to set the front side bus frequency for the
installed CPU (usually 133MHz, 100MHz or 66MHz).
