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, contacts
or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or con-
nectors 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 system chassis cover for installa-
tion 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 com-
ponents. Perform the upgrade instruction procedures described at an ESD worksta-
tion 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 chas-
sis. If a wrist strap is unavailable, establish and maintain contact with the system
chassis throughout any procedures requiring ESD protection.

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 deliver increased system bandwidth and improved performance. The advantages of
DDR4 are its higher bandwidth and its increase in performance at a lower power than DDR3/
DDR3L/DDR2. It is not compatible with DDR3/DDR3L/DDR2.
• Graphics
The integrated Intel®HD graphics engine delivers an excellent blend of graphics performance
and features to meet business needs. It provides excellent video and 3D graphics with out-
standing graphics responsiveness. These enhancements deliver the performance and compat-
ibility needed for today’s and tomorrow’s business applications. Supports 1 x VGA, 1 x DVI-I
(DVI-D signal) and 1 x HDMI interfaces for triple display outputs.
• PCI Express
PCI Express is a high bandwidth I/O infrastructure that possesses the ability to scale speeds
by forming multiple lanes. The x4 PCI Express lane supports transfer rate of 4 Gigabyte per
second (2 directions). The PCI Express architecture also supports high performance graphics
infrastructure by enhancing the capability of a PCIe x16 Gen 3 at 16GB/s bandwidth (8GB/s in
each direction).
• 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. The bandwidth of the SATA 3.0 will be limited by
carrier board design.
• Gigabit LAN
Two Intel®Gigabit LAN controllers (Intel®I210AT PCI Express Gigabit Ethernet controller and
Intel®I219LM Gigabit Ethernet Phy) support up to 1Gbps data transmission.
• Audio
The Realtek ALC888S-VD2-GR audio codec provides 5.1 channel High Definition audio output.
Important:
The 5V_standby power source of your power supply must support ≥720mA.
• 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.
• RTC Timer
The RTC installed on the system board allows your system to automatically power-on on the
set date and time.
• 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.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB ports, the
5V_standby power source of your power supply must support ≥1.5A. For 3 or more
USB ports, the 5V_standby power source of your power supply must support ≥2A.
• 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
Management Event) signal. However, if your system is in the Suspend mode, you can power-
on the system only through an IRQ or DMA interrupt.
Important:
The 5V_standby power source of your power supply must support ≥720mA.

• Wake-On-PS/2
This function allows you to use the PS/2 keyboard or PS/2 mouse to 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.
• USB
The system board supports the new USB 3.0. It is capable of running at a maximum transmis-
sion speed of up to 5 Gbit/s (625 MB/s) and is faster than USB 2.0 (480 Mbit/s, or 60 MB/s)
and USB 1.1 (12Mb/s). USB 3.0 reduces the time required for data transmission, reduces
power consumption, and is backward compatible with USB 2.0. It is a marked improvement in
device transfer speeds between your computer and a wide range of simultaneously accessible
external Plug and Play peripherals.

The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) 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 DIMM Module
Single Channel
DIMMs are on the same channel.
DIMMs in a channel can be identical or
completely different. However, we highly
recommend using identical DIMMs.
Not all slots need to be populated.
Dual Channel DIMMs of the same memory configuration
are on different channels.
Important:
You can populate either Channel A or Channel B first.
Note:
The system board used in the following illustrations may not resemble the actual
board. These illustrations are for reference only.
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 DIMM socket on the system board.
4. Push the “ejector tabs” at the ends of the socket to the side.
