CPU Internal Frequency [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
100 and 133. Select [Manual] if you want to make
changes to the subsequent 2 fields. Note that select-
ing a frequency higher than the CPU manufacturer
recommends may cause the system to hang or crash.
See System Hangup on page 67.
CPU 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 fre-
quency multiple between the CPU’s internal frequency and external frequency. This
must be set in conjunction with CPU External (FSB) Frequency to match the speed
of your CPU. Configuration options: [2.0x] [2.5x] [3.0x]...[7.0x] [7.5x] [8.0x]
CPU External (FSB) Freq. (MHz) (when CPU Speed is set to [Manual])
This feature tells the clock generator what frequency to send to the CPU and chipset.
The external frequency (bus frequency) multiplied by the bus multiple equals the
CPU’s internal frequency (the CPU speed). Configuration options: [100] [103]
[105]...[174] [177] [180]
Multiples of 100
(for a 100MHz FSB)
Multiples of 133
(for a 133MHz FSB)
