CPU.Ratio.Setting.[Auto]

Allows you to adjust the ratio between CPU Core Clock and FSB Frequency. Use

the <+> and <-> keys to adjust the value. The values may vary depending on the

CPU installed. Configuration options: [Auto] [06.0] [07.0]–[XX.X]

The following two items appear only when you set the Ai.Overclock.Tuner item

to [Manual].

FSB.Frequency.[XXX]

Displays the frequency sent by the clock generator to the system bus and PCI bus.

The value of this item is auto-detected by the BIOS. Use the <+> and <-> keys to

adjust the frequency. You can also type the desired frequency using the numeric

keypad. The values range from 200 to 800. Refer to the table below for the correct
