CPU Clock Ratio
This field allows you to select the CPU clock ratio. Most CPU clock ratios are
fixed inside the CPU by the manufacturers that prohibit you to make any
changes. In this case, the setting in this field will make no change to the CPU
clock ratio since it locks and is automatically determined.
Auto Detect PCI Clk
When “Enabled” is selected, the mainboard will detect the presence of devices
on PCI slots. When there is no device present on some of the PCI connectors,
the clock on the related PCI slot will be disabled to reduce the Electro-Magnetic
Interference (EMI).
Spread Spectrum
When Spread Spectrum is enabled, the EMI radiation on this mainboard will be
reduced.
