Hardware Installation
2.4 Jumper Settings for the CPUs Front Side Bus
Jumper JP3
CPUs 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 on the next
page.
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.
Note:
Intel Pentium

II, Intel Pentium

III processors and Intel Celeron
TM
processors support VID (Voltage Identification). The switching voltage
regulator on the system board will automatically set the voltage regulator
according to the voltage of the processor.
