4.4 Advanced Menu
CPU Frequency Multiple (when CPU Speed is set to [Manual])
This field is for unlocked processors only. If your processor frequency
multiple is locked, you cannot access this field. This field allows you to set
the frequency multiple between the CPU’s internal frequency (CPU speed)
and external frequency.
CPU/PCI Frequency (MHz)
(when CPU Speed is set to [Manual])
This feature tells the clock generator what frequency to send to the system
bus and PCI bus. The bus frequency (external frequency) multiplied by the
bus multiple equals the CPU speed. The setting of this field depends on
the CPU Frequency Multiple.
CPU Speed [Manual]
When the motherboard is set to JumperFree™ mode, this field allows you
to select the internal frequency of the CPU. Select [Manual] if you want to
make changes to the two subsequent fields.
Selecting a frequency higher than the CPU manufacturer recommends
may cause the system to hang or crash!
