CPU Ratio [Auto]
Allows you to set the ratio between the CPU Core Clock and the FSB Frequency. Use <+>
and <-> to adjust the ratio. The valid value ranges vary according to your CPU model.
FSB Frequency [200]
Displays the frequency sent by the clock generator to the system bus and PCI bus. Use the
<+> and <-> keys to adjust the FSB frequency. You can also type the desired FSB frequency
using the numeric keypad. The values range from 200 to 600.
PCIE Frequency [100]
Use the <+> and <-> keys to adjust the PCIE frequency. You can also type the desired PCIE
frequency using the numeric keypad. The values range from 100 to 200.
