Note on CPU Overclocking:
1. If you have successfully booted system with or without CPU overclock,
you still can do another CPU overclock in BIOS Setup. Please enter
BIOS Setup, choose "Frequency/Voltage Control" menu, and take
the "Use Linear" option of the "Use CPU Linear Frequency". Then
configure the "CPU Clock" item to raise your CPU clock.
2. CPU overclocking should take all components on board into account.
If you fail in BIOS overclocking, you will not be able to restart system.
In such case, power off system and clear CMOS by JBAT1 as stated
below and then restart your system. And remember to reconfigure
whatever should be reconfigured.

the power button on the case and simultaneously press down the
"Insert" key of the keyboard until you see the initial bootup screen
appear. And remember you should also enter CMOS BIOS Setup
and choose "Load Optimized Defaults" to restore default BIOS .
