CPU Internal Frequency
In JumperFree Mode, this field allows you to select the internal frequency
of your CPU. Select [Manual] if you want to make changes to the subse-
quent 2 fields. Note that selecting a frequency higher than the CPU manu-
facturer recommends may cause the system to hang or crash. See System
Hangup on page 60.
CPU Frequency Multiple
(When CPU Internal Frequency is set to [Manual])
This field sets the frequency multiple between the CPUs internal frequency
and external frequency. In JumperFree Mode, when CPU Internal Fre-
quency is set to [Manual], this must be set in conjunction with FSB/
SDRAM Freq. (MHz) to match the internal frequency of your CPU. Con-
figuration options vary according to the external frequency of your CPU.
FSB:SDRAM:PCI Freq. Ratio
(When CPU Internal Frequency is set to [Manual])
This field determines the frequency ratio among the Front Side Bus, SDRAM,
and PCI bus. You may set the memory clock frequency in synchronous or
asynchronous mode with respect to the Front Side Bus frequency. Configu-
ration options: [66:100:33] [100:100:33] [133:133:33] [133:100:33]
FSB/SDRAM/PCI Freq. (MHz)
(When CPU Internal Frequency is set to [Manual])
According to the previous setup field FSB:SDRAM:PCI Freq.
Ratio, this field offers 32 sets of Front Side Bus, SDRAM, and
PCI bus frequencies for you to choose.
Available options
when FSB:SDRAM:PCI Freq. Ratio
is set to [133:133:33]
