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.

2.1 Installing the CPU

1. Before you insert the 1151-Pin CPU into the socket, please check if the PnP cap
is on the socket, if the CPU sur face is unclean, or if there are any bent pins in the
socket. Do not force to insert the CPU into the socket if above situation is found.
Other wise, the CPU will be seriously d amaged.

2. Unplug all power cables be fore 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 Memor y Technology 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.

2.4 Expansion Slots (PCI and PCI Express Slots)

ere is I PCI slot and 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 make necessary hardware settings for the card before you start
the installation.

PCI slot:

e PCI1 is used to install expansion cards that have 32-bit PCI interface.

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 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”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”

when a jumper cap is placed on these 2 pins.

Clear CMOS Jumper
(C LR MOS 1)
(see p.1, No. 21)

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 pin2 and pin3 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.

Clear CMOSDefault

Z270 Pro4

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

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.

System Panel Header
(9-pi n PANEL1)
(see p.1, No. 14)

PWRBTN (Power Switch):

Connec t to the power switch on the chassi s front panel. You may congure the way to
turn o your system using the power switch.

RESET (Reset Switch):
Connec t to the reset switch on the chassis front panel. Press the reset sw itch to restart
the computer if the compute r freezes and fails to perform a normal 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 activity LED on the chassis front panel. e LED is on
when the hard drive i s reading or writing data.

e front panel design may dier by chassis. A front panel module mainly consists
of power switch, reset switch, power LED, hard dr ive activity LED, speak er 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 heade r 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”.

2.7 M.2_SSD (NGFF) Module Installation Guide

e M.2, also known as the Next Generation Form Factor (NGFF), is a small size and
versatile card edge connector that aims to replace mPCIe and mSATA. e Ultra M.2
Sockets (M2_1 and M2_2) support SATA3 6.0 Gb/s module and M.2 PCI Express module
up to Gen3 x4 (32 Gb/s).
* If M2_1 is occupied by a SATA-type M.2 device, SATA3_5 will be disabled.
* If M2_2 is occupied by a SATA-type M.2 device, SATA3_0 will be disabled.

Installing the M.2_SSD (NGFF) Module
