2.4 Jumper Settings for the CPUs Front Side Bus
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.
Warning:
Overclocking a 66MHz FSB
processor to 100MHz will
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.
