2-5.3 Frequency Ratio Select (By SW1 DIP1-DIP5)
• The AMD Athlon and Duron processors provides four Frequency ID signals
(FID) for the system controller to indicate the SYSTCLK multiplier at which
the processor core operates. Normally, multiplier (or bus ratio) is detected
automatically. Therefore, if the processor does not support the function, then
“Bus Ratio” can not be selected.
• When DIP5 of SW1 is on, LED
“SSF1” will be on, and light is on, it means
that Bus Ratio Select Function is enabled. So as long as your CPU supports
Bus Ratio Select function, then Bus Ratio can be selected by users.
