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 outstanding graphics responsiveness.
These enhancements deliver the performance and compatibility 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
The Gigabit Ethernet Controllers support data transmission at 1Gbps.
Audio
The audio codec provides 5.1 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 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.
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 Management 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 session 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 1. It is capable of running at a maximum transmission speed of up 5 Gbit/s, or 625 MB/s, faster than 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.

Chapter 2 – Hardware Installation

Board Layout

  Note: Some optional components are only available upon request.
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.

Standby Power LED

Important:
When the Standby Power LED lit red, it indicates that there is power on the system board. Power-off the PC then unplug the power cord prior to installing any devices. Failure to do so will cause severe damage to the motherboard and components.

System Memory

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 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.

Features

• Two 288-pin UDIMM up to 64GB (non-ECC support)
• Dual Channel DDR4 2400/2666MHz

Installing the 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 DIMM socket on the system board
4. Make sure the notch on memory card is aligned to the key on the socket.

Please follow the steps below to install the memory card into the socket.
Step 1:
Press the eject tabs at both ends of the socket outward and downward to release them from the locked position.
Step 2:
Insert the memory card into the slot while making sure the notch and the key are aligned. Press the card down firmly with fingers while applying and maintaining even pressure on both ends.
Step 3:
The tabs snap automatically to the edges of the card and lock the card in place.

Removing the DIMM Module
Please follow the steps below to remove the memory card from the socket.
Step 1:
Press the eject tabs at both ends of the socket outward and downward to release them from the locked position.
Step 2:
The memory card ejects from the slot automatically.
Step 3:
Hold the card by its edges and remove it from the slot.

The system board is equipped with a surface mount LGA 1151 socket. This socket is exclusively designed for installing a LGA 1151 packaged Intel CPU.
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 processed only if the LGA 1151 socket comes with the protective cap.

Note:
The system board used in the following illustrations may not resemble the actual board. These illustrations and photos are for reference only.

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.
   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 install the CPU.

4. Unlock the ocket by pressing the load lever down, moving it sideways until it escapes the retention tab. Lift the load lever up when it’s released.

5. Lift the load lever and the load plate all the way up as shown in the photo.

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

7. 1.Insert the CPU into the socket.
   The gold triangular mark on the CPU must align with the chamfer corner of the CPU socket shown in the photo. Important:
   The CPU will fit in only one orientation and can easily be seated without exerting any force.
   7-2. Two keys on the socket and notches on the CPU also facilitate alignment.
   7-3.The CPU’s notch will fit into the socket’s alignment key when it’s seated in the correct orientation.

8. Close the load plate then push the load lever down.
   While closing the load plate, make sure the front edge of the load plate slides under the retention knob.

9. Press down the load lever and hook it under the retention tab.

Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circulation across the CPU and heat sink, the CPU will overheat damaging both the CPU and system board.
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.

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.

4. Screw tight two of the spring screws at opposite corners into the mounting holes. And then proceed with the other two spring screws.

5. Connect the CPU fan’s cable to the CPU fan connector on the system board.

Cooling fans provide adequate air circulation throughout the chassis and dissipate heat to prevent overheating of the system board and components. The 4-pin fan provides PWM to modulate fan speed whereas the 3-pin fans modulate fan speed via voltage modulation.
BIOS Setting
Configure the Smart Fans in the Advanced menu (“SIO NUVOTON6116D” submenu) of the BIOS. Refer to chapter 3 for more information.

Power Connector

Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1. An ATX12V power supply unit has a standard 24-pin ATX main power connector that must be in-serted into the 24-pin connector. The 8-pin +12V power connector enables the delivery of more +12VDC current to the processor’s Voltage Regulator Module (VRM).
The power connectors from the power supply unit are designed to fit the 24-pin and 8-pin connectors in only one orientation.
Make sure to find the proper orientation before plugging the connectors.
The system board requires a minimum of 300 Watt power supply to operate. Your system configuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the minimum power requirement. To ensure that adequate power is provided, we strongly recommend that the system is supplied with a minimum of 400 Watt power.
Important:
Insufficient power supplied to the system may result in instability or malfunction of the add-in boards and peripherals. Calculating the system’s approximate power usage is important to ensure that the power supply meets the system’s consumption requirements.
Chassis Intrusion

The board supports the chassis intrusion detection function. Connect the chassis intrusion sensor cable from the chassis to this connector. When the system’s power is on and a chassis intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion occurred, the alarm will sound only when the system restarts.

When the system’s power is on, this LED will light up. When the system is in the S1 (POS – Power On Suspend) state, it will blink at 1-second intervals. When the system is in the S3 (STR – Suspend To RAM) state, it will blink at 4-second intervals.
ATX-SW – ATX Power Switch
This switch is used to power on or off the system.

S/PDIF The Sony/Philips Digital Interface (S/PDIF) connector is for audio output to external audio equipment. The S/PDIF port may be mounted on a card- edge bracket. Install the card-edge bracket to an available slot at the rear of the system chassis then connect the audio cable to the S/PDIF connector. Make sure pin 1 of the audio cable is aligned with pin 1 of the S/PDIF connector.

Battery The lithium ion battery addendum supplies power to the real-time clock and CMOS memory as an auxiliary source of power when the main power is shut off. Insert a coin cell battery into the holder and make sure the polarities are correctly oriented — the cap side (rimmed rounded edge) is negative and should be facing the holder; the flat side with a + mark is positive and should be facing away from the holder.
Safety Measures

• There exists explosion hazard if the battery is incorrectly installed.
• Replace only with the same or equivalent type recommended by the manufacturer.
• Dispose of used batteries according to local ordinances.

SMBus

The SMBus (System Management Bus) connector is used to connect the SMBus device. It is a multiple device bus that allows multiple chips to connect to the same bus and enable each one to act as a master by initiating data transfer.

Chapter 3 – BIOS Settings

The BIOS is a program that takes care of the basic level of communication between the CPU and peripherals. It contains codes for various advanced features found in this system board.
The BIOS allows you to configure the system and save the configuration in a battery-backed CMOS so that the data retains even when the power is off. In general, the information stored in the CMOS RAM of the EEPROM will stay unchanged unless a configuration change has been made such as a hard drive replaced or a device added.
It is possible that the CMOS battery will fail causing CMOS data loss. If this happens, you need to install a new CMOS battery and reconfigure the BIOS settings.
The BIOS is constantly updated to improve the performance of the system board; therefore the BIOS screens in this chapter may not appear the same as the actual one. These screens are for reference purpose only.

Default Configuration
Most of the configuration settings are either predefined according to the Load Optimal Defaults settings which are stored in the BIOS or are automatically detected and configured without requiring any actions. There are a few settings that you may need to change depending on your system configuration.
Entering the BIOS Setup Utility
The BIOS Setup Utility can only be operated from the keyboard and all commands are keyboard commands. The commands are available at the right side of each setup screen. The BIOS Setup Utility does not require an operating system to run. After you power up the system, the BIOS message appears on the screen and the memory count begins. After the memory test, the message “Press DEL to run setup” will appear on the screen. If the message disappears before you respond, restart the system or press the “Reset” button. You may also restart the system by pressing the and keys simultaneously.
