How to tackle with Jumpers:
• Do not remove the jumper when power is on. Always make
sure the power is off before changing any jumper settings.
Otherwise, mainboard could be damaged.
• In the Jumper setting diagram, all jumper pins covered with
black marks stand for closed pins by jumper caps.
2-7.1 Switch 1 System Clock Adjust
This mainboard is built with a 4-DIP Switch on board, by which user
can adjust the CPU clock generator for the Pentium 4 processor in-
stalled on board. Yet users are not recommended to take Switch 1 as
a tool for overclocking. It is saver and more advisable for users to
select the CPU clock as close as possible to the one marked on the
selected CPU. Default setting of SW1 is 100MHz.

Advice from our Engineering Team :
CPU Overclocking should always take all other components on board
into account. No matter what Host clock your CPU has , any attempt to
set your CPU to higher frequency than the host will get no guaranty of
success. Instead, you are taking the risk of breaking the stability of
your CPU as well as the mainboard.
