CPU Clock Ratio
Use this item to select a multiplier for the system frontside bus (FSB) frequency.
The value of the multiplier must be set so that:
Multiplier x Frontside Bus Frequency = CPU Clock Speed
For example, if you have a processor that is rated to run at 450 MHz and the
system is running a frontside bus frequency of 100 MHz, you should select a
multiplier of 4.5 so that:
4.5 (Multiplier) x 100 MHz (frontside bus) = 450 MHz (CPU clock)
Auto Detect PCI Clk
When enabled the mainboard automatically disables the clock source for a PCI
slot which does not have a module in it, reducing EMI (ElectroMagnetic
Interference). The default is Enabled.
