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

Tip: When should I Clear CMOS?
1. Boot fails because of over-clocking…
2. Forget password…
3. Troubleshooting…
If the housing has been designed with an audio port on the front panel, you’ll be able to
connect onboard audio to front panel through this connector. By the way, please remove 5-6
and 9-10 jumper caps from the Front Audio Connector before connecting the cable. Please do
not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on the front panel.
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.

Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage automatically
during power-on.
Setting CPU Frequency
This motherboard is CPU jumper-less design, set CPU frequency through 1MHz stepping CPU
Overclocking in the BIOS. CPU Core Frequency = CPU external frequency 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 over-clocking.
(Users do the over- clocking at their own risk!)

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
references only.
Tip: When you fail to over-clock, you could:
Clear CMOS (JP14) to restore the default setting.
After turning power on, press “Home” immediately until the screen
appears.
