WARNING
Please realize that there is a certain risk involved with overclocking, including
adjusting the setting in the BIOS, applying Untied Overclocking Technology, or
using the third-party overclocking tools. Overclocking may affect your system
stability, or even cause damage to the components and devices of your system.
It should be done at your own risk and expense. We are not responsible for possible
damage caused by overclocking.
CAUTION!
1. Due to the chipset limitation, the actual memory size may be less than
4GB for the reservation for system usage under Windows®OS.
2. You can choose to use two of the three monitors only. D-Sub, DVI-D and
HDMI monitors cannot be enabled at the same time. Besides, with the
DVI-to-HDMI adapter, the DVI-D port can support the same features as
HDMI port.

2. Installation
This is a Mini-ITX form factor (6.7" x 6.7", 17.0 x 17.0 cm) motherboard. Before you
install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts into it.
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.
2.1 Screw Holes
Place screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched off or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

2.3 Installation of Memory Modules (SO-DIMM)
AD2550-ITX motherboard provides two 204-pin DDR3 (Double Data Rate 3) SO-
DIMM slots.
1. It is not allowed to install a DDR or DDR2 memory module into DDR3
slot; otherwise, this motherboard and SO-DIMM may be damaged.
2. Please install the memory module from DDR3_A2 slot for the rst
priority.
Installing a SO-DIMM
Please make sure to disconnect power supply before adding or
removing SO-DIMMs or the system components.
Step 1. Unlock a SO-DIMM slot by pressing the retaining clips outward.
Step 2. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
The SO-DIMM only ts in one correct orientation. It will cause perma-
nent damage to the motherboard and the SO-DIMM if you force the SO-
DIMM into the slot at incorrect orientation.
Step 3. Firmly insert the SO-DIMM into the slot until the retaining clips at both
ends fully snap back in place and the SO-DIMM is properly seated.

interface.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off 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.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.

2.6 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.
Jumper Setting Description
Clear CMOS
(CLRCMOS1, 2-pin jumper)
(see p.2 No. 13)
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS in-
cludes system setup information such as system password, date, time, and
system setup parameters. To clear and reset the system parameters to de-
fault setup, please turn off the computer and unplug the power cord from the
power supply. After waiting for 15 seconds, use a jumper cap to short 2 pins
on CLRCMOS1 for 5 seconds.
