The following items are user-configurable only when the Overclock

Profile item is set to [Manual].

Selecting a very high CPU frequency may cause the system to become

unstable! If this happens, revert to the default setting.

CPU Frequency [XXX] (value is auto-detected)CPU Frequency [XXX] (value is auto-detected)

CPU Frequency [XXX] (value is auto-detected)

Indicates the frequency sent by the clock generator to the system bus and

PCI bus. The bus frequency (external frequency) multiplied by the bus

multiple equals the CPU speed. The value of this item is auto-detected by

BIOS. The values range from 200 to 400. Refer to the following table for

the correct Front Side Bus and CPU External Frequency settings.
