Further Notes on CPU Overclocking:
1. If you have successfully booted system, with or without CPU
overclock, you still can try 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 and then
restart your system. And remember to reconfigure whatever should
be reconfigured.
3. If your system is already fixed in a cabinet or case, you may not like
to take the trouble to clear CMOS. Then power on your system with
the power button on the PC case and simultaneously press down the
"Insert" key on the keyboard until you see the initial bootup screen
appear. And remember you should also enter CMOS BIOS Setup
instantly and choose "Load Optimized Defaults" to restore default
BIOS .
