CPU Speed [Manual]
When the motherboard is set to JumperFree™ mode, this field allows you
to select the internal frequency of your CPU. Available options include
multiples of 66, 100 and 133. Select [Manual] if you want to make changes
to the subsequent 2 fields. Note that selecting a frequency higher than the
CPU manufacturer recommends may cause the system to hang or crash. See
System Hangup later in this section.
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.
