CPU : System Frequency Multiple (when CPU Speed is set to [Manual])
This field is for unlocked processors only. If your processor’s Frequency
Multiple is detected locked, you will not be able to access this field. This
field sets the frequency multiple between the CPU’s internal frequency (CPU
speed) and external frequency. This must be set in conjunction with Sys-
tem/PCI Frequency (MHz) to match the speed of your CPU. Configura-
tion options: [2.0x] [2.5x] [3.0x]...[7.0x] [7.5x] [8.0x]
System/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.

2 fields. Note that selecting a frequency higher
