2-4.4 Frequency Ratio Select (By Sw3 Dip1-Dip4) - SOLTEK SL-75LIV User Manual

2-4.4 Frequency Ratio Select (By SW3 DIP1-DIP4)

• The AMD Athlon and Duron processors provides four Frequency ID signals
(DIP1-DIP4) (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 SW3 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.
