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
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.
NOTICE : Setting of multiplier
12.5x or above will depend on
the type of CPU on board .
*
Setting of will depend on the type of CPU on board Multiplier 12.5x or
