2. Install CPU
3. Install Memory
4. Install other expansion cards
5. Connect all signal lines, cables, panel control circuits and power adaptor.
6. Power on the computer and complete BIOS setup.
Key components of this motherboard are Integrated circuit, and these components
could be easily damaged by electrostatic influence. So, before installing this unit, please
always keep the following precautions in mind:
1. Hold the board by edges, don’t touch any components or plug and socket pins.
2．Wear anti-static gloves/wrist strap while touching the integrated circuit components, such as
CPU, RAM, etc.
3．Put those unused or uninstalled components in static shielding bags or trays.
4．Please first check the power switch is off before connecting the power plug.
2.3 Install CPU
Pls follow the steps below to install CPU
（1）Open the cover of CPU socket on the motherboard.
（2）Hold CPU by both sides. Make the triangle mark of its Pin1 aim at the socket notch mark
and insert CPU into the socket.
（3）Check the installation of CPU and close the socket cover.
Pls follow the steps below to install CPU FAN:
（1）Make sure the CPU FAN heat sink fits the CPU surface and fix the fan on the motherboard.
（2）Connect the fan power cord to the CPU FAN socket.
2.4 Install Memory
Board with 2x DIMM slots. Please pay attention to following two points when installing the
memory bank:
1. Please first align the notch of the RAM with the socket and press the memory bank
downward softly to tighten the connection.

2. Select a proper memory bank that matches your motherboard.
2.5 Jumper Settings
Please refer to following instructions to setup jumpers before installing your hardware devices.
Remark: How to identify the PIN1 of all jumpers and interfaces: Please observe the word mark
on the side of the plug socket, which will be a “1” or bold line or triangular symbol; And please
look at the back of PCB, each with a square shape will be the PIN 1; and all the jumpers’ PIN1
have a white arrow on the side.。
2.5.1 CMOS Clear/Hold Jumper Setting（JCC）
CMOS is powered by the onboard button cell. Clear CMOS will lead to permanent elimination
of previous system settings and back to the original system setting (factory default).
Steps。
（1）Turn off the computer and disconnect the power supply.
（2）Use Jumper Cap J36/J37 Pin1-2 short for 5~6 sec. Then restore the default setting with
Pin2-3 connected.
（3）Turn on the computer, then press “DEL” key to enter BIOS setting and reload optimal
defaults.
（4）Save and Exit
