Overclocking Jumper Setting (JFSB)
Jumper labeled JFSB is located on the mainboard providing users with CPU overclocking
feature. The host bus speed can be set as 100/133MHz or AUTO. Refer to the chart
below for the location of these jumpers, and the table for information on how to set them..
If CPU FSB is set as Auto (default), the system detects the CPU FSB (front side bus)
automatically. If CPU FSB is set as 100MHz, the system will run at 100MHz even if a
processor with 66MHz or 133MHz FSB is installed. Setting up to 133MHz using proces-
sors with 100MHz bus speed is also supported. However, whether or not the system can
be overclocked depends on your processors capability. Whether the processor is bus
ratio locked or unlocked should also be taken into account. For bus ratio unlocked proces-
sor, this overclocking feature can be implemented by setting CPU FSB as 100/133MHz,
meanwhile adjusting the bus ratio (multiplier) lower in CPU SpeedEasy Setup in AWARD
BIOS CMOS Setup. You can also adjust the CPU frequency by running StepEasy II. We do
not guarantee the overclocking system will be stable.
Installation Instructions
Clear CMOS (JCC)
If you want to clear CMOS, unplug the AC power supply first, close JCC (pin1 & pin2)
once, set JCC back to the normal status with pin2 & pin3 connected, then power on the
system.
Normal status:
(Default)
