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.
Chapter 2 Installation

H310M-G/M.2
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 two 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
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.
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 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 3 PCI Express slots on the motherboard.
PCIe slots:
PCIE1 (PCIe 2.0 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 2.0 x1 slot) is used for PCI Express x1 lane width 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”.
Clear CMOS Jumper
(CLRCMOS1)
(see p.1, No. 10)
Short: Clear CMOS
Open: Default
CLRCMOS1 allows you to clear the data in CMOS. e data in CMOS includes
system setup information such as system password, date, time, and system setup
parameters. To clear and reset the system parameters to default setup, please
turn o the computer and unplug the power cord, then use a jumper cap to short
the pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper
cap aer clearing the CMOS. 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.
2-pin Jumper
If you clear the CMOS, the case open may be detected. Please adjust the BIOS option
“Clear Status” to clear the record of previous chassis intrusion status.

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.
PWRBTN (Power Button):
Connect to the power button on the chassis front panel. You may congure the way to turn
o your system using the power button.
RESET (Reset Button):
Connect to the reset button on the chassis front panel. Press the reset button 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
button, reset button, power LED, hard drive activity LED, speaker and etc. When connect-
ing your chassis front panel module to this header, make sure the wire assignments and the
pin assignments are matched correctly.
