CPU Speed [Manual]
When the motherboard is set to JumperFree™
mode, this field allows you to select the internal
Multiples of 100
frequency of your CPU. Available options (for 100MHz FSB)
include multiples of 66, 100, and 133. Select
[Manual] if you want to make changes to the
two subsequent fields. Note that selecting a
Multiples of 133
frequency higher than the CPU manufacturer
(for 133MHz FSB)
recommends may cause the system to hang or
crash.
CPU : System Frequency Multiple (when CPU Speed is set to [Manual])
This field is for unlocked processors only. If your processor frequency
multiple is detected locked, you cannot access this field. This field sets the
frequency multiple between the CPU's internal frequency (CPU speed) and
external frequency. Set this field in conjunction with System/PCI Frequency
(MHz) to match the speed of the CPU. Configuration 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.
