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.

►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.
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 DP++, HDMI, and
VGA interfaces for diaplay outputs.
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
Two Realtek®8111HN PCI Express Gigabit Ethernet controllers for two individual LAN ports are
equpped to support data transmission at 1Gbps (10/100/1000Mbps).
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.
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 accessibl
external Plug and Play peripherals.
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.
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.

Important:
Electrostatic discharge (ESD) can damage your board, pro-
cessor, 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

• Two 288-pin DDR4 UDIMM vertical sockets
• Supports 2133/2440 MHz DDR4 SDRAM
• Dual channel memory interface
• Supports maximum of 32GB system memory
►System Memory
Features
The system board supports the following memory interface.
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.
Single Channel DIMMs are on the same channel. DIMMs in a channel can be identi-
cal 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.
