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.
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.
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 Intel®Gigabit LAN controllers (Intel®I211AT and Intel®I219LM PCI Express Gigabit Eth-
ernet controllers) support up to 1Gbps data transmission.
Audio
The Realtek ALC888 audio codec provides high-performance of 7.1+2 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.
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).
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 3.1 Gen 2. It is capable of running at a maximum
transmission speed of up to 10 Gbit/s (1.2 GB/s) and is faster than USB 3.1 Gen 1 (5 Gbit/s, or
625 MB/s), USB 2.0 (480 Mbit/s, or 60 MB/s) and USB 1.1 (12Mb/s). USB 3.1 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.
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.

board. These illustrations and photos are for reference only.
Important:
1. Before you proceed, make sure (1) the LGA 1151 socket comes with a protec-
tive cap, (2) the cap is not damaged and (3) the socket’s contact pins are not bent.
If the cap is missing or the cap and/or contact pins are damaged, contact your
dealer immediately.
2. Make sure to keep the protective cap. RMA requests will be accepted and pro-
cessed only if the LGA 1151 socket comes with the protective cap.
Installing the CPU
1. Make sure the PC and all other peripheral devices connected to it have been powered
down.
2. Disconnect all power cords and cables.
3. Locate the LGA 1151 CPU socket on the system board.
4. Unlock the socket by pressing
the load lever down, moving it
sideways until to escape the
retention tab. Lift the load lever
up when it’s released.

Important:
The CPU socket must not come in contact with anything other than the CPU. Avoid
unnecessary exposure. Remove the protective cap only when you are about to in-
stall the CPU.

6. Remove the protective cap from
the CPU socket. The cap is
used to protect the CPU socket
against dust and harmful par-
ticles. Remove the protective
cap only when you are about to

HARDWARE INSTALLATION
Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circula-
tion across the CPU and heat sink, the CPU will overheat damaging both the CPU and system
board.
1. Before you install the fan / heat sink, you must apply a thermal paste onto the top of
the CPU. The thermal paste is usually supplied when you purchase the fan / heat sink
assembly. Do not spread the paste all over the surface. When you later place the heat
sink on top of the CPU, the compound will disperse evenly.
Some heat sinks come with a patch of pre-applied thermal paste. Do not apply thermal
paste if the fan / heat sink already has a patch of thermal paste on its underside. Peel
the strip that covers the paste before you place the fan / heat sink on top of the CPU.
2. Place the heat sink on top of the CPU. The 4 spring screws around the heat sink, which
are used to secure the heat sink onto the system board, must match the 4 mounting
holes around the socket.
3. Orient the heat sink so that the CPU fan’s cable is nearest the CPU fan connector.
XCPU
4. Screw tight two of the spring screws at opposite corners into the mounting holes. And
then proceed with the other two spring screws.

Note:
A boxed Intel®processor already includes the CPU fan and heat sink assembly. If
your CPU was purchased separately, make sure to only use Intel®-certified fan and
heat sink.
