Installing Hardware
Warning
The motherboard consists of a great number of ICs and other
components. These ICs are apt to be damaged by the static
charge. Therefore, the user must make the following prepara-
tions before formal installation:
1. Turn off the power of the computer. It is preferable
the power cord be unplugged.
2. Take care not to contact the metal wires and theirs
joints on the motherboard when handling it.
3. It is preferable that the anti-static wrist strap be worn.
4. Before the ICs are installed, the components of the
motherboard should be placed on the anti-static mat
or bag.
5. When you remove the plug on the ATX power sup-
ply of the motherboard, make sure the switch of the
power supply is in OFF state.
Installing the motherboard onto the computer case:
For most of the computer cases, the multiple fixing holes left
on their bottoms can be used for securing the motherboard and
no short circuit can occur therefrom. During your operation,
take care not to allow the screws to contact any circuit or part
on PCB. When circuits on the surface of the motherboard get
close to the fixing holes, you can use the plastic sheet to sepa-
rate the screws from the board surface so as to avoid damage or
failure of the motherboard.

2. Installing CPU
Please install the CPU (central processing unit) in accordance with the follow-
ing procedures:
1) Find the processor receptacle Socket AM2/AM2+ on the motherboard;
2) Open the fixing bar beside the receptacle SocketAM2/AM2+ to the
height of a 90-degree angle, as shown in the figure below;
3) Note that, at pin-hole area of the left and right sides of the bottom of
Socket AM2/AM2+ (marked with “Socket AM2/AM2+), one pin hole
is missing. This is used for indicating the direction for the installation of
CPU. There should be drawing indicating the direction, like a triangle, at
the edge of the CPU you bought;
4) Align Socket AM2/AM2+ to the indicated direction on CPU, slowly
insert CPU into Socket AM2/AM2+, and then put back the fixing bar;
Note
To install the CPU correctly, you should make sure the indicated
direction on CPU matches that of Socket AM2/AM2+. Otherwise,
the CPU might be damaged.
5) After the installation of CPU, you should install the CPU fan onto the
CPU. To secure the fan, you should make the buckle of CPU fan engaged
in the corresponding position at the two sides of Socket AM2/AM2+;
6) Once CPU and its securing parts are installed, you should then plug the
power cord of the fan into the corresponding receptacle on the motherboard.

2.3 Installing memory card
Please install the memory card in accordance with the following
procedures:
1) Remove the white tenon at the two ends of the interface slot
for the memory card;
2) Align the golden finger of the memory card to the groove of the
interface slot and pay attention the concave hole of golden
finger should be aligned to the convex point of the slot;
3) Finally, insert the memory card into the interface slot gently. If
no error occurs at the moment, insert the card forward in the
slot till the white buckle is automatically engaged in the con-
cave hole at the two sides of the memory card.
Note
In order to avoid damages to the motherboard or the components,
the user must make sure the power supply to the computer is
turned off before the memory card or other system component is
installed or removed.As the groove is set at the golden finger of the
DDRII DIMM memory card, the memory card can only be inserted
into the slot with one direction. During installation, the user only
needs to align the golden finger and the dual-channel groove of the
interface slot and insert it gently. To avoid damage, never apply
excessive force in that process.
Remove outward the white tenon at
the two ends of the interface slot
for module of the memory card.

2.4 Installing extension interface card
Installing graphics card
This motherboard provides one interface slot for PCIEx 16 graphics
card. When you install the PCIE graphics card, you should note that
groove of the golden finger must be exactly engaged into the interface
slot. In that process, it is preferable that you be in grounded state, and
you should carefully take out the graphics card from the anti-static
bag. Then align the graphics card to the PCIE interface slot and insert
it. After that, tighten the screw on the metal baffle. See Figure 2.4.

See Figure 2.5.
2) CLR_CMOS(CMOS port)
The correct time, system hardware and other information are saved in
the CMOS memory of the motherboard. The shutoff the computer’s
power supply won’t cause the loss of this information, for the CMOS
is powered by the battery on the motherboard. Its settings are seen in

BIOS Setup
Note
The descriptions relating to BIOS in this Manual can only be used for reference as the
BIOS version of the motherboard is upgraded continuously. OEM provides no guarantee
that the contents in this Manual be consistent with the information you acquire.
BIOS is a basic I/O control program saved in the Flash Memory. Bridging the
motherboard and the operating system, BIOS is used for managing the setup of the
related parameters between them. When the computer is activated, the system is
first controlled by the BIOS program. First, a self-detection called POST is per-
formed to check all hard devices and confirm the parameters of the synchronous
hardware. Once all detections are completed, BIOS will hand over the controlling to
the operating system (OS). The correct setup of BIOS plays a key role in stably
running the system and optimizing its performance.
The CMOS Setup will save the set parameters in the built-in CMOS SRAM on the
motherboard. When the power is shut off, the lithium battery on the motherboard
will supply power CMOS SRAM continuously. The BIOS setup program will
allow you to configure the following items:
1. HD drive, floppy drive and peripheral devices;
2. Video display type and display items;
3. Password protection;
4. Power management characteristics.
A. State of BIOS Setup
When the computer is started up, BIOS will run the self-detection (Post) program.
This program includes series of diagnosis fixed in BIOS. When this program is
executed, the following information will appear if any error is found:
Press F1 to Run Setup
Press F 2 to Load default values and continue
To enter BIOS, you can press F1; to load the default values and enter the system,
you can press F2. After the self-detection process is completed, you can press DEL
to enter the BIOS interface if no error is found. If the indicative information disap-
pears before you can act, you can shut off the computer and turn on it again, or you
can press the key RESET on the machine case. To restart your computer, you can
also simultaneously press <Ctrl>+<Alt>+<Delete>.
