Hardware Installation
JP1 and JP2 are used to select the front side bus of the CPU
installed on the system board. The default setting is Auto. The system
will run according to the front side bus of the CPU installed on the
system board.
Important:
•
If you are using a CPU whose frequency has been locked
by the manufacturer, overclocking will have no effect.
•
Overclocking may result to the CPU’s or system’s instability
and are not guaranteed to provide better system
performance. If you are unable to boot your system due to
overclocking, make sure to set these jumpers back to their
default settings.
