Chapter 2 Installation
is is a Deep mini-ITX form factor motherboard. Before you install the
motherboard, study the conguration 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
1. Before you insert the 1700-Pin CPU into the socket, plea se check if the PnP cap is on the
socket, if the CPU surface is unclean, or if there are any bent pins in the sock et. 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 four 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel conguration, 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, DDR 2 or DDR3 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 DIMM into the slot at incor rect
orientation.

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 make necessary hardware settings for the card before you start
the installation.
PCIe slot:
PCIE1 (PCIe 4.0 x16 slot) is used for PCIe 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”.
B660-ITX
Clear CMOS Jumper
(CLRCMO S1)
(see p.1, No. 10)
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 aer 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.
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.

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

RESET (Reset B utton):
Connec t to the reset button on the chassi s front panel. Press the reset button to restart the
computer if the computer f reezes and fails to per form a normal restar t.
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 operating. e LED keeps blinking when the system is in S1/S3 sleep state. e
LED is o when the system is in S4 slee p state or powered o (S5).
HDLED (Ha rd Drive Activity LED):
Connec t to the hard drive activity LED on the chassis front panel. e LED is on when the
hard drive is reading or wr iting data.
e front panel design may dier by chassis. A front panel module mainly consists of powe r
button, reset button , power LED, hard dr ive activity LED, speaker and etc. When connecting your chassi s front panel module to thi s header, make sure the wire a ssignments and the
