1.3.Motherboard Layout
Important:

Make sure the CPU is fully seated and level in the socket.
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
Be very careful when handling the CPU. Make sure not to bend or break any pins on the back. Hold the processor only by the
edges and do not touch the bottom of the processor.
Use the following procedure to install the CPU onto the motherboard.
1.Unhook the socket lever by pushing down and away from the socket.
2.Lift the load plate. There is a protective socket cover on the load plate to protect the socket when there is no CPU installed.
3.Remove the protective socket cover from the load plate.
4.Remove the processor from its protective cover, making sure you hold it only by the edges.
It is a good idea to save the cover so that whenever you remove the CPU, you have a safe place to store it.
5.Align the notches in the processor with the notches on the socket.
6.Lower the processor straight down into the socket with out tilting or sliding it into the socket
7.Close the load plate over the CPU and press down while you close and engage the socket lever.
8.There are many different fan types that can be used with this motherboard. Follow the instruction that came with you fan
assembly. Be sure that the fan orientation is correct for your chassis type and your fan assembly.

2.4.Inslling the Motherboard
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.
Be sure that the CPU fan assembly has enough clearance for the chassis covers to lock into place and for the expan-
sion cards. Also make sure the CPU Fan assembly is aligned with the vents on the covers.
The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors
on the socket and damaging the CPU!
SO-DIMM slot
2.3.Installing Memory DIMMs
Your new motherboard has 1 slots for SO-DIMM memory. They support DDR4 memory technology. There must be at least
one memory bank populated to ensure normal operation. Use the following the recommendations for installing memory.
Install into DIMM: You only can install the DIMM into this slot.

2.6.1.MSATA slot
2.5.Securing the Motherboard into the Chassis
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.Ensure that the fan assembly is aligned with the chassis vents according to the fan assembly instruction.
4.Secure the motherboard with a minimum of eight-to-ten screws.
This slot connect to MSATA hard disk drives,the maximum support 6 gb/s transmission rate.
2.6.Connecting Cables and Setting Switches
This section takes you through all the connections and switch settings necessary on the motherboard. This will include:
Power Connections
4-pin ATX 12V power
Internal Headers
Front panel
USB Headers
Serial ATA III
Chassis Fans

2.6.3.Back Panel IO Connector
2.6.2.Power connectors:HDD_PWR1、CPU_12VIN、CPU_12VOUT、12V_PCIE_IN1-10，12V_PCIE_OUT1-8
The silk-screen“CPU_12VIN”connector is for CPU power supply,when using the mining power, need to use a cable which
on both sides are 4PIN power ports, shorting between the“CPU_12VIN”and“CPU_12VOUT”connectors.
The silk-screen“12V_PCIE_IN1-10”connectors are for the motherboard power supply , connected to the power supply.
The silk-screen“12V_PCIE_OUT1-8”connectors are just for graphics card auxiliary power supply port,Graphics card
external 12V 6PIN or 8PIN power port,please directly connect to PSU PCI-E 6PIN or 8PIN connectors.
The silk-screen“HDD_PWR1”connector is for HDD power supply,the function of this connector is to supply power to the
hard disk from the motherboard.It is designed for colorfull mining PSU,when using an ordinary PSU, this connector on the
motherboard can not be used,because the PSU can supply power to the hard disk directly .

UseParts
The standard RJ-45 jack is for connection to single Local Area Network (LAN).
You can connect a network cable to it.
LAN Jack
Onboard HDMI port, connect to HDMI Monitor.HDMI
These connectors are for attaching USB devices such as keyboard, mouse,
or other USB-compatible devices.
USB Ports
Connect the fan cables to the fan connectors on the motherboard, making sure that the�black wire of each cable matches
the ground pin of the connector.
2.6.4.CPU, Chassis, and Power fan connectors (4-pin CPU_FAN, 3-pin PWR_FAN)
These connectors connect to Serial ATA 3.0 6Gb/s Gb/s hard disk drives and optical drives via Serial ATA 3.0 6Gb/s Gb/s
signal cables.
2.6.5.Serial ATA 3.0 6Gb/s Gb/s connectors (7-pin)

System power LED (2-pin PLED)
This 2-pin connector is for the system power LED. Connect the chassis power LED cable to this connector. The system
power LED lights up when you turn on the system�power, and blinks when the system is in sleep mode.
Hard disk drive activity LED (2-pin IDE_LED)
This 2-pin connector is for the HDD Activity LED. Connect the HDD Activity LED cable to this connector. The IDE LED lights

2.6.6.System panel connector

The PCI Express x16 slot�is reserved for a graphics or video card. The bandwidth of the x16 slot is up to 8GB/sec.
When installing a PCI Express 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.
(Warm prompt: when you want to set up 12pcs�graphics�card for mining, it is recommended to use WIN10 1703 version
system, 8 Gb of memory)

PCI Express x16 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 configura-
tion, use the CLR_CMOS Jumper to clear data.
2.6.8.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 2) or Remove the jumper cap
3.Turn the AC power supply back on.
