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.

INTRODUCTION
XFeatures
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.
DDR3L
DDR3L requires less voltage (1.35V) than DDR3 (1.5V). DDR3L SDRAM modules support
1867MHz for DDR modules.
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 HDMI
and 1 x LVDS/eDP (eDP optional) interfaces for triple display 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 RTL8111H-CG Ethernet controllers support up to 1Gbps data transmission.
Audio
The Realtek ALC269Q audio codec provides 4-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.
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 exter-
nal Plug and Play peripherals.

HARDWARE INSTALLATION
• Two 204-pin SODIMM up to 8GB
• Dual Channel DDR3L 1867MHz
XSystem 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.
