B460TM-ITX
is is a in 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.
Failure to do so may cause physical injuries to you 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

2.1 Installing the CPU
1. Before you insert the 1200-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 (SO-DIMM)
is motherboard provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM
slots.
It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot;
otherwise, this motherboard and SO-DIMM may be damaged.
e SO-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.

2.4 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. 5)
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
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.
