Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on. It's not necessary to set CPU core voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB
clock x CPU Ratio. However, all CPU now selling in the market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but only change CPU
FSB clock to achieve overclocking.
(Users do the overclocking at their own risk!!)
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup

FSB = 100MHz-400MHz by 1MHz Stepping CPU Overclocking

Note:
With CPU speed changing rapidly, there might be faster CPU on the market
by the time you received this installation guide. This table is kindly for your

Warning: Intel 945G / 945P chipset support maximum 1066MHz (266MHz*4)
system bus; higher clock setting may cause serious system damage.

JP14 Clear CMOS
You can clear CMOS to restore system default setting. To clear the CMOS, follow
the procedure below.
1.
Turn off the system and unplug the AC
power.
2.
Remove ATX power cable from
connector PWR3.
3.
Locate JP14 and short pins 2-3 for a few
seconds.
4.
Return JP14 to its normal setting by
shorting pin 1 & pin 2.
5.
Connect ATX power cable back to
connector PWR3.

JP28 Keyboard/Mouse Wakeup Jumper
This motherboard provides keyboard / mouse wake-up function. You can use JP28
to enable or disable this function, which could resume your system from suspend
mode with keyboard or mouse. The factory default setting is "Disable" (1-2), and
you may enable this function by setting the jumper to 2-3.
Tip: When should I Clear CMOS?
1. Boot fails because of overclocking...
2. Forget password...
3. Troubleshooting...
