2.1.Safety Instructions
To reduce the risk of fire, electric shock, and injury, always follow basic safety precautions.
Remember to remove power from your computer by disconnecting the AC main source before removing or installing any equip-
ment from/to the computer chassis.
2.2.Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU or memory. You need to purchase a CPU, a CPU fan assembly, and
memory to complete this installation.
2.2.1.Installing the CPU
When installing a CPU, always remember to install a CPU heatsink. An CPU heatsink is necessary to prevent overheating and main-
tain system stability. Follow the steps below to ensure correct APU and heatsink installation. Wrong installation can damage both
the APU and the motherboard.
1. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-degree angle.
2. Locate the pin one (denoted by a small triangle) of the CPU socket and the CPU..
3. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that
any violation of the correct installation procedures may cause permanent damages to your motherboard.
4. Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always
close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded
into the socket.
5. Locate the CPU fan connector on the motherboard.
6. Position the cooling set onto the retention mechanism. Hook one end of the clip to hook first.
7. Then press down the other end of the clip to fasten the cooling set on the top of the retention mechanism. Locate the Fix Lever
and lift up it.
8. Fasten down the lever.
9. Attach the CPU Fan cable to the CPU fan connector on the motherboard.

Your new motherboard has 2 slots for DDR4 memory. They support dual channel DDR4 memory technology. There must be at least
one memory bank populated to ensure normal operation. Use the following the recommendations for installing memory.
One DIMM: Install into DIMM1 or DIMM2. You can install the DIMM into any slot, however, slot 1 is preferred.
Two DIMMs: Install into DIMM1 & DIMM2,to build dual channel.
Use the following procedure to install memory DIMMs into the slots on the motherboard. Note that there is only one gap near the
center of the DIMM slot. This slot matches the slot on the memory DIMM to ensure the component is installed properly.
Unlock a DIMM slot by pressing the module clips outward.
Align the memory module to the DIMM slot, and insert the module vertically into the DIMM slot. The plastic clips at both sides
of the DIMM slot automatically lock the DIMM into the connector.

2.4.Installing the Motherboard
2.5.Installing the I/O Shield
2.6.Securing the Motherboard into the Chassis
The sequence of installing the motherboard into the chassis depends on the chassis you are using and if you are replacing an
existing motherboard or working with an empty chassis. Determine if it would be easier to make all the connections prior to
this step or to secure the motherboard and then make all the connections. Use the following procedure to install the I/O
shield and secure the motherboard into the chassis.
The motherboard kit comes with an I/O shield that is used to block radio frequency transmissions, protects internal compo-
nents from dust and foreign objects, and promotes correct airflow within the chassis.
Before installing the motherboard, install the I/O shield from the inside of the chassis. Press the I/O shield into place and
make sure it fits securely. If the I/O shield does not fit into the chassis, you would need to obtain the proper size from the
chassis supplier.
Most computer chassis have a base with mounting studs or spacers to allow the mother board to be secured to the chassis
and help to prevent short circuits. If there are studs that do not align with a mounting hole on the motherboard, it is recom-
mended that you remove that stud to prevent the possibility of a short circuit.
1.Carefully place the motherboard onto the studs/spacers located inside the chassis.
2.Align the mounting holes with the studs/spacers.
3.Align the connectors to the I/O shield.
4.Ensure that the fan assembly is aligned with the chassis vents according to the fan assembly instruction.
5.Secure the motherboard with a minimum of eight-to-ten screws.
Be sure that the CPU fan assembly has enough clearance for the chassis covers to lock into place and for the expansion
cards. Also make sure the CPU Fan assembly is aligned with the vents on the covers.

2.7.Connecting Cables and Setting Switches
2.7.1.ATX power connectors (24-pin ATXPWR, 4-pin ATX12V)
These connectors are for an ATX power supply. The plugs from the power supply are designed to fit these connectors in only
one orientation. Find the proper orientation and push down firmly until the connectors completely fit.
2.7.2.Power off charging and PS2 mouse/keyboard wake up jumper
Only the PS2+USB ports on the back panel can support the shutdown charging function.You can open this function by short-
ing 2-3pin.
Note: the white silk-screen "1" on the PCB is the first needle of jumper.
This section takes you through all the connections and switch settings necessary on the motherboard. This will include:

hard disk drives and optical drives via Serial ATA 3.0
6Gb/s signal cables.
These connectors are for USB 2.0 ports. Connect the USB module cable to any of these connectors, then install the module to a
slot opening at the back of the system chassis. These USB connectors comply with the USB 2.0 specification that supports up to
480Mbps connection speed.
2.7.4.USB2.0 connectors

This connector supports several chassis-mounted functions.
2.7.6.System panel connector
This connector is for a chassis-mounted front panel audio I/O module that supports either High Definition Audio or AC`97 audio
standard. Connect one end of the front panel audio I/O module cable to this connector.
2.7.8.Front panel audio connector
PCI Express x1 Slot
PCI Express3.0 x16 Slot
The PCI Express x1 slots that are designed to accommodate less bandwidth-intensive cards, such as a modem or LAN card. The x1
slot provides 250 MB/sec bandwidth.
The PCI Express3.0 x16 slot is reserved for a graphics or video card. The bandwidth of the x16 slot is up to 4GB/sec (8GB/sec
concurrent).
When installing a PCI Express3.0 x16 card, be sure the retention clip snaps and locks the card into place. If the card is not seated
properly, it could cause a short across the pins. Secure the card’s metal bracket to the chassis back panel with the screw used
to hold the blank cover.

The motherboard has one M.2 slot,support PCI-e x4 and SATA SSD,support 2242/2280 size SSD.
Please install M.2 SSD correctly in the slot following the following steps:
1. please use a screwdriver to remove the screws and studs in order, and then lock the stud first when the actual M.2 SSD is found
to be suitable for the screw hole position.
2. insert the M.2 SSD into the slot in a inclined angle.
3. press M.2 SSD, then lock the screw.
2.7.10.M.2 slot
There is a CMOS RAM on board that has a power supply from external battery to keep the system configuration data. With the
CMOS RAM, the system can automatically boot OS every time it is turned on. If you want to clear the system configuration, use
the CLR_CMOS Jumper to clear data.
2.7.9.Clear CMOS Jumper: CLR_CMOS
You can clear CMOS by shorting 1-2 pin. Before you clearing the CMOS, following next procedure:
1.Turn off the AC power supply and connect pins 1 and 2 together using the jumper cap.
2.Return the jumper setting to normal (pin 1 or 2) or Remove the jumper cap
3.Turn the AC power supply back on.
