Frequency/Voltage Control
This item enables you to set the clock speed and system bus for your system.
The clock speed and system bus are determined by the kind of processor you
have installed in your system.

CPU Ratio (X 8)
Use this item to select a multiplier for the system frontside bus (FSB) fre-
quency. 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 DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM and
PCI slots.
Spread Spectrum (Spectrum +/- 0.5%)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-
Magnetic Interference) generated by the system.
CPU Host/AGP/PCI Clock (Default)
Use the CPU Host Clock to set the frontside bus frequency for the installed
processor (usually 133 MHz, 100 MHz or 66 MHz).
