CPU : System Frequency Multiple, (if CPU Speed set to [Manual])
This field is for unlocked processors only and will not be available to standard
AMD processors. If the processor frequency multiple is detected as being
locked, you cannot access this field. For unlocked processors, this field sets
the frequency multiple between the CPU’s internal frequency (CPU speed)
and the external frequency. Set this field in conjunction with the System/
PCI Frequency (MHz) to match the speed of the CPU. Configuration
options: [5x/14x] [5.5x] [6.0x]...[12.0x] [12.5x]
Advanced Menu
CPU Speed [Manual]
When the motherboard is set to JumperFree™ mode, this field sets the
internal frequency of your CPU. Select [Manual] if you want to make
changes to the next two fields. Note that selecting a frequency higher than
the CPU manufacturer recommends may cause the system to hang or crash.
Configuration options: [Manual] [750MHz] [1000MHz]
System/PCI Frequency (MHz)
(if CPU Speed 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.
Configuration ranges from 100/33 to 227/57.
