2-7.3 Jclk1: Cpu & Str(S3) Support - SOLTEK B7A-F User Manual

2-7.3 JCLK1: CPU Clock Adjustable
1. Setting JCLK1 all pins open is for
adjusting CPU clock by BIOS setup after
booting system. If overclocking by BIOS
setup fails, the system will automatically
reboot with default CPU clock 100MHz.
2. Setting JCLK1 1-2 closed will allow users
to set the CPU clock manually by JCLK2
or by BIOS. However, if the system gets
down due to overclocking and cannot
reboot, users must implement the nVIDIA
Boot-Failure-Reboot Procedures.
3. Setting JCLK1 2-3 closed will fix CPU
clock to 100MHz and will not allow users
to make any adjustment and JCLK2 is
invalid hereby.
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 "Advanced Chipset Features"
menu, then configure the "FSB Freqency" 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 .
