This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reason-
able protection against harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the re-
ceiver is connected.
• Consult the dealer or an experienced radio TV technician for help.

Warranty
1. Warranty does not cover damages or failures that arised from misuse of the product,
inability to use the product, unauthorized replacement or alteration of components and
product specifications.
2. The warranty is void if the product has been subjected to physical abuse, improper in-
stallation, modification, accidents or unauthorized repair of the product.
3. Unless otherwise instructed in this user’s manual, the user may not, under any circum-
stances, attempt to perform service, adjustments or repairs on the product, whether in
or out of warranty. It must be returned to the purchase point, factory or authorized ser-
vice agency for all such work.
4. We will not be liable for any indirect, special, incidental or consequencial damages to
the product that has been modified or altered.
Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components or devices even
before installing them in your system unit. Static electrical discharge can damage computer
components without causing any signs of physical damage. You must take extra care in han-
dling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you
are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the components, con-
tacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or
connectors by their ends.
Safety Measures
• To avoid damage to the system, use the correct AC input voltage range.
• To reduce the risk of electric shock, unplug the power cord before removing the sys-
tem chassis cover for installation or servicing. After installation or servicing, cover the
system chassis before plugging the power cord.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and other
components. Perform the upgrade instruction procedures described at an ESD
workstation only. If such a station is not available, you can provide some ESD pro-
tection by wearing an antistatic wrist strap and attaching it to a metal part of the
system chassis. If a wrist strap is unavailable, establish and maintain contact with
the system chassis throughout any procedures requiring ESD protection.

X Features
Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the system at the set
time interval. If the system hangs or fails to function, it will reset at the set time interval so that
your system will continue to operate.
DDR4
DDR4 delivers increased system bandwidth and improves performance. The advantages of
DDR4 provide an extended battery life and improve the performance at a lower power than
DDR3/DDR2.
Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of
up to 6Gb/s (SATA 3.0), it improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s.
Gigabit LAN
The Realtek RTL8119-CG Gigabit Ethernet Controllers support data transmission at 1Gbps.
Audio
The Realtek ALC888S-VD2-GR audio codec provides 7.1 channel High Definition audio output.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is
supported via the onboard LAN port or via a PCI LAN card that uses the PCI PME (Power Man-
agement Event) signal. However, if your system is in the Suspend mode, you can power-on the
system only through an IRQ or DMA interrupt.
Wake-On-USB
This function allows you to use a USB keyboard or USB mouse to wake up a system from the
S3 (STR - Suspend To RAM) state.
ACPI STR
The system board is designed to meet the ACPI (Advanced Configuration and Power Interface)
specification. ACPI has energy saving features that enables PCs to implement Power Manage-
ment and Plug-and-Play with operating systems that support OS Direct Power Management.
ACPI when enabled in the Power Management Setup will allow you to use the Suspend to RAM
function.
With the Suspend to RAM function enabled, you can power-off the system at once by pressing
the power button or selecting “Standby” when you shut down Windows®without having to go
through the sometimes tiresome process of closing files, applications and operating system.
This is because the system is capable of storing all programs and data files during the entire
operating session into RAM (Random Access Memory) when it powers-off. The operating ses-
sion will resume exactly where you left off the next time you power-on the system.
Power Failure Recovery
When power returns after an AC power failure, you may choose to either power-on the system
manually or let the system power-on automatically.
RTC Timer
The Real Time Clock (RTC) installed on the system board allows your system to automatically
power-on on the set date and time.

Chapter 2 - Hardware Installation
Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives,
add-in boards, and other components. Perform installation procedures at an ESD
workstation only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a metal part of
the system chassis. If a wrist strap is unavailable, establish and maintain contact
with the system chassis throughout any procedures requiring ESD protection.
Note:
Specifications of these components are model-specific. Please refer to the specifi-
cations for detail.

• 260-pin SO-DIMM up to 64GB
• DDR4 3200MHz
X System Memory
Features
The system board supports one dual channel DDR4 SO-DIMM memory module.
Single Channel (SC)
Data will be accessed in chunks of 64 bits from the memory channels.
Dual Channel (DC)
Data will be accessed in chunks of 128 bits from the memory channels. Dual channel provides
better system performance because it doubles the data transfer rate.
Installing the SO-DIMM Module
Before installing the memory module, please make sure that the following safety cautions are
well-attended.
1. Make sure the PC and all other peripheral devices connected to it has been powered
down.
2. Disconnect all power cords and cables.
3. Locate the SO-DIMM socket on the system board
4. Make sure the notch on memory card is aligned to the key on the socket.
