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.
