CPU Clock Ratio
Enables you to set the CPU clock. The CPU clock ratio times the CPU
Host/PCI Clock should equal the core speed of the installed processor.
Example:
CPU Clock Ratio
8
CPU Host/PCI Clock
x 100
Installed CPU clock speed
800 MHz
Auto Detect PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM and
PCI slots.
Spread Spectrum (Enabled)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-
Magnetic Interference) generated by the system.
CPU Host/3V66/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).
