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 over­tighten the screws! Doing so may damage the motherboard.

Chapter 2 Installation

English

Z270 Extreme4

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 surface 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. 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.

Dual Channel Memory Conguration

e DIMM only ts in one correct orientation. It will cause permanent damage to the
motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

2 Populated Populated
3 Populated Populated Populated Populated

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 Memory 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 Express Slots)

ere are 6 PCI Express slots on the motherboard.

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 x1 slot) is used for PCI Express x1 lane width cards.

PCIE6 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics cards.

PCIe Slot Congurations

For a better thermal environment, please connect a chassis fan to the motherboard’s chas­sis fan connector (CHA_FAN1, CHA_FAN2 or CHA_ FAN3 ) when using multiple graphics
cards.

Before installing an expansion card, please make sure that the power supply is switched o
or the power cord is unplugged. Please read the documentation of the expansion card and
make necessary hardware settings for the card before you start the installation.

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
(CLRMOS1)
(see p.1, No. 25)

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

2.6 Onboard Headers and Connectors

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

Connect the power
switch, reset switch and
system status indicator on
the chassis to this header
according to the pin
assignments below. Note
the positive and negative
pins before connecting
the cables.

PWRBTN (Power Switch):

Connect to the power switch on the chassis front panel. You may congure the way to turn
o your system using the power switch.

RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset switch to restart the
computer if the computer freezes and fails to perform a normal restart.

PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. e LED is on when the
system is operating. e LED keeps blinking when the system is in S1/S3 sleep state. e
LED is o when the system is in S4 sleep state or powered o (S5).

HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. e LED is on when the
hard drive is 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 drive activity LED, speaker and etc. When connect­ing your chassis front panel module to this header, make sure the wire assignments and the
pin assignments are matched correctly.

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.
