Chapter 2 Installation

is is a Micro 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.

2.1 Installing the CPU

1. Before you insert the 1200-Pin CPU into the socke t, 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 c ables before in stalling 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 channe l conguration, you always need to in stall identical (the same

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

2. It is unable to activate Dual Channel Memor y Technolog y with 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.

e DIMM only ts in one correct orientation. It will cause permanent dam age to
the mothe rboard and the DIMM if you force the DIMM into the slot at incor rect

2.4 Expansion Slots (PCI Express Slots)

ere are 4 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 x16 slot) is used for PCI Express x16 lane width graphics cards.

PCIE2 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width 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 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

“O pen”.

Clear CMOS Jumper

(CLRMO S1)

(see p.7, No. 18)

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 CLR MOS1 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-pin Jumper

English

18

If you clear the CMOS, the case open may be detec ted. Please adjust the BIOS option
“Clear Status” to clear the record of previou s chassis intrusion status.

2.6 Onboard Headers and Connectors

SPEAKER

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.

1. High De nition Audio supports Jack Sen sing, but the panel wire on the chassis

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
connec t 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”.
