Jumper JP3
CPUs Front Side Bus Select
The default setting of jumper JP3 is
Auto - the system will automatically
run according to the FSB of the
processor. If you wish to overclock a
66MHz FSB processor to 100MHz,
set pins 1, 2 and 3 to Off. If you
want a 100MHz FSB processor to
run at 66MHz, set pins 2 and 3 to
On. Refer to the figure below.

Warning:
Overclocking a 66MHz FSB processor to 100MHz willl
provide better system performance. However, not all 66MHz
FSB processors are capable of running at 100MHz bus
speed. Therefore, if you are unable to boot your system when
set at 100MHz, make sure to set JP3 back to its default
setting.
