These fields provide you with information about the systems current operating
status. You cannot make changes to these fields.
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 Clock Ratio (Auto)
Use the CPU Host/SDRAM/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 Jumpless
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)
.
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 (Enabled)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-
Magnetic Interference) generated by the system.
CPU Host/SDRAM/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).
