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 socke t, please check if the PnP cap is on the socket, if the CPU sur face is unclean, or if th ere are any b ent pins in the socket. Do not force to insert the CPU into the socket if above situ ation is found. Other wise, the CPU wil l be seriously d amaged.
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 in stall identical (the same
brand, speed , size and chip-type) DDR4 DIMM pairs.
2. It is unable to ac tivate Dual Channel Memory Technology with only one memory module instal led.
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 orie ntation. It will cause permanent dam age to the mothe rboard and the DIMM if you force the DIMM into the slot at incor rect orientation .

2.4 Expansion Slots (PCI Express Slot)
ere is 1 PCI Express slot slot 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 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
(CLRMOS1)
(see p.7, 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 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
H370M-ITX/ac
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 header s and connectors. Placing jumper caps over the headers and connectors will cause permanent damage to the motherboard.
System Panel Header
(9-pin PANEL1)
(see p.7, No. 12)
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 chassi s front panel. P ress 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 ac tivity LED on the chassis front panel. e LED is on when the hard drive i s reading or writing data.
e front panel de sign may dier by chassis. A front pane l 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.

The M.2, also known as the Next Generat ion 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 M Key type 2230/2242/2260/2280 M.2 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 de-
vice, SATA3_1 will be disabled.
Installing the M.2_SSD (NGFF) Module

be aware that the M.2 (NGFF) SSD
module only ts in one orientation.
Step 6
Tighten the screw with a screwdriver

to secure the module into place.
Please do not overtighten the screw as
this might damage the module.
