B660D4-P1
is is a Proprietary 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

English

2.1 Installing the CPU
1. Before you insert the 1700-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.

2.2 Installing the CPU Fan and Heatsink

English

2.3 Installing Memory Modules (SO-DIMM)
is motherboard provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM
slots.
1. Carefully insert the SO-DIMM memory modules into the slot at a 30-degree angle.
2. Push down until the modules snap into place.
e SO-DIMM only ts in one correct orientation. It will cause permanent damage to
the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at incorrect
orientation.
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.

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. 6)
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.
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.

2.5 Onboard Headers and Connectors
Serial ATA3 Connector
(SATA1:
see p.1, No. 5)
is SATA3 connector
supports SATA data cables
for internal storage devices
with up to 6.0 Gb/s data
transfer rate.
CPU Fan Connectors
(4-pin CPU_FAN1)
(see p.1, No. 2)
is motherboard
provides a 4-Pin CPU fan
(Quiet Fan) connector. If
you plan to connect a 3-Pin
CPU fan, please connect it
to Pin 1-3.
Chassis Fan Connectors
(4-pin CHA_FAN1)
(see p.1, No. 3)
Please connect fan cables
to the fan connectors and
match the black wire to the
ground pin.
Serial Port Header
(9-pin COM1)
(see p.1, No.8)
is COM1 header supports
a serial port module.
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.
