Chapter 2 Installation

is is a Mini-ITX 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 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 two 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 Memory Technology w ith only one memor y module
installed.

3. It is not allowed to install a DDR, DDR2 or DDR 3 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 damage to the
motherboard and the DIMM if you force the DIM M into the slot at incorrect orientation.

ere is 1 PCI Express slot on the motherboard.

Before installing an expansion card, ple ase 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.

PCIe slot:

PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 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
(C LR MOS 1)
(see p.1, No. 14)

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-pin Jumper

Z370M-ITX/ac

If you clear the CMOS, the case open may be detected. Please adjust the BIOS option “Clear
Status” to clear the record of previous chassi s intrusion status.

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these
heade rs and connectors. Plac ing jumper caps over the hea ders and connectors will cause
permanent damage to the motherboard.

2.7 M.2_SSD (NGFF) Module Installation Guide

The 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. The Ultra M.2
Socket (M2_1) supports SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3
x4 (32 Gb/s).
Please be noted that if the Ultra M.2 Socket (M2_1) is occupied by a SATA-type M.2 de­vice, SATA3_0 will be disabled.

Installing the M.2_SSD (NGFF) Module

Step 1

Prepare a M.2_SSD (NGFF) module
and the screw.
