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.
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.
Async AGP/PCI CLK (Sync)
This item allows you to select the fixed clock to generate the output to AGP/PCI frequency.
CPU Clock (100 MHz)
Use the CPU Host Clock to set the frontside bus frequency for the installed processor
(usually 133 MHz, 100 MHz or 200MHz).
CPU Clock Ratio (8X)
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.
CPU VID (0.8375V)
This item allows users to adjust CPU Voltage; and the function supports only in Prescott
CPU.
