1. JP14 Clear CMOS
Everything you need to boot this
motherboard is included in this
Easy Installation Guide. For more
information, a complete Online
User's Manual can be found in the
Bonus Pack CD Disc. Thanks for
the help of saving our earth.

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 p ower cable from connector PWR2.
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 p ower cable back to connector PWR2.
Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…
3. Troubleshooting…
2. JP17 FSB Select Jumper
This jumper allows you to select CPU FSB frequency manually. If you are not an overclocker, we
recommend you keep the default jumper setting.

1. Pull up the CPU socket lever and up to
90-degree angle.
2. Locate Pin 1 in the socket and look fo
r
a (golden) cut edge on the CPU uppe
r
interface. Match Pin 1 and cut edge.
Then insert the CPU into the socket.
3. Press down the CPU socket lever and
finish CPU installation.
Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan, you
can also plug it on System FAN (FAN2) or AUX FAN (FAN3) connector.
This motherboard comes with a 20-pin ATX power connector and an extra 4-pin connecto
r
as shown below. Make sure you plug in the right direction. We strongly recommend you to
insert the 4-pin connector before connecting the 20-pin connector.

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports C PU VID function. The CPU core voltage will be automatical l
y
detected.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the
BIOS setup, and no jumpers or switches are needed. The default setting is "1MHz
stepping mode", which you can change to "table select mode" by enabling the "Spread
Spectrum" in the bios. so that you can adjust the FSB from "CPU Host/PCI/3V66 Clock"
for overclocking.
3. Installing Processor
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.
