Chapter 2 Installation
is is an ATX form factor motherboard. Before you install the motherboard, study
the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Make sure to unplug the power cord before installing or removing the motherboard
components. Failure to do so may cause physical injuries and damages to motherboard
components.
• In order to avoid damage from static electricity to the motherboard’s components,
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
• Hold components by the edges and do not touch the ICs.
• Whenever you uninstall any components, place them on a grounded anti-static pad or
in the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not over-
tighten the screws! Doing so may damage the motherboard.

2.3 Installing Memory Modules (DIMM)
is motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel conguration, you always need to install identica l (the same
brand, speed , size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memor y Technology with only one or three
memor y module installed.
3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

2.4 Expansion Slots (PCI Express Slots)
ere are 5 PCI Express slots on the motherboard.
Before installing an ex pansion card, please make sure that the power supply is
switched o or the power cord is unplugged. Plea se read the documentation of the
expan sion card and mak e necessary hardware settings for the card before you start
the installation.
PCIe slots:
PCIE1 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE3 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIE4 (PCIe 3.0 x16 slot) is used for PCI Express x8 lane width graphics cards.
PCIE5 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics cards.

2.5 Jumpers Setup
e illustration shows how jumpers are setup. When the jumper cap is placed on
the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is
“Open”.

Clear CMOS Jumper
(CLRMOS1)
(see p.8, No. 21)
CLRMOS1 allows you to clear the data in CMOS. e data in CMOS includes
system setup information such as system password, date, time, and system setup
parameters. To clear and reset the system parameters to default setup, please turn
o the computer and unplug the power cord, then use a jumper cap to short the
pins on CLR MOS1 for 3 seconds. Please remember to remove the jumper cap aer
clearing the CMOS. If you need to clear the CMOS when you just nish updating
the BIOS, you must boot up the system rst, and then shut it down before you do
the clear-CMOS action.
e Clear CMOS Button has the same function as the Cl ear CMOS jumper.

2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over
these header s and connectors. Placing jumper caps over the headers and connectors
will cause permanent damage to the motherboard.

(9-pin PANEL1)
(see p.8, No. 19)
PWRBTN (Power Button):
Connec t to the power button on the chassi s front panel. You may congure the way
to turn o your system using the powe r button.
RESET (Reset Button):
Connec t to the reset button on the chassi s front panel. Press the reset button to
restar t the computer if the computer freezes and fails to perform a nor mal restart.
PLED (Syste m Power LED):
Connec t to the power status indicator on the chassis front panel. e LED i s on when
the system is ope rating. e LED keeps blinking when the system i s in S1/S3 sleep
state. e LED is o when the system is in S4 sleep state or powered o (S5).
HDLED (Ha rd Drive Activity LED):
Connec t to the hard drive ac tivity LED on the chassis front panel. e LED is on
when the hard drive i s reading or writing data.
e front panel de sign may dier by chassis. A front pane l module mainly consists
of power button , reset button, power LED, hard dr ive activity LED, speaker and etc.
When connecting your chassis front panel module to this head er, make sure the wire
assig nments and the pin assig nments are matched correctly.
