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 deter-
mined by the kind of processor you have installed in your
system.

Auto Detect DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal
of free DIMM and PCI slots.
CPU Internal Core Speed (Auto)
The value for this item will be automatically detected by the
system. If you set this value to Manual the CPU Host/PCI
Clock and CPU Clock Ratio items appear.
Spread Spectrum (Enabled)
If you enable spread spectrum, it can significantly reduce the
EMI (Electro-Magnetic Interference) generated by the system.
CPU Host/PCI Clock &CPU Clock Ratio
These items appear if you have set the CPU Internal Core
Speed to Manual. Use the CPU Host/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. The multiple times the frontside bus must equal
the core speed of the installed processor - e.g., 3.5 (multiple)
x 100 MHz (frontside bus) = 350 MHz (installed processor
clock speed).
