CPU Clock Ratio (0 X)
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/PCI slots.
Spread Spectrum (Enabled)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic
Interference) generated by the system.
Clock Control By (Auto)
Use this item to set the CPU Host Clock frequency to Auto or by manual setting. Select
“Manual” to activate the following items and set each item manually.
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.
