Chapter 2 Installation

is is an ATX form factor motherboard. Before you install the motherboard, study
the conguration 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.

1. Before you insert the 1200-Pin CPU into the socket, please check if the PnP cap is on the
socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not
force to in sert the CPU into the socket if above situation is found. Otherwise, the CPU
will be seriously damaged.

2. Unplug all power cables before installing the CPU.

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 conguration, you always need to install identical (the same

brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Dual Channel Me mory Technology w ith only one or three

memory 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.

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 make 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.

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
(CLRMO S1)
(see p.1, No. 30)

CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short the pins on CLRMOS1 for 5 seconds. However, please do not clear the
CMOS right aer you update the BIOS. 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. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed. Please remember toremove the jumper cap aer clearing the CMOS.

2.6 Onboard Headers and Connectors

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

e front panel design may dier by chassis. A front panel module mainly consists
of power button, reset button, power LED, hard drive 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.

must support HDA to function correctly. Please follow the instructions in our
manual and chassis manual to install your system.

2. If you use an AC’97 audio panel, please install it to the front panel audio header by

the steps below:
A. Connect Mic_IN (MIC) to MIC2_ L.
B. Conne ct Audio_R (RIN) to OUT2_R and Audio_ L (LIN) to OUT2_ L.
C. Connect Ground (GND) to Ground (GND).
D. MIC_ RET and OUT_RET are for the HD audio panel only. You don’t need to
connect them for the AC’97 audio panel.
E. To activate the front mic, go to the “FrontMic” Tab in the Realtek Control panel
and adjust “Recording Volume”.
