Introduction

Static Electricity Precautions

It is quite easy to inadvertently damage your PC, system board, components
or devices even before installing them in your system unit. Static electrical dis­charge can damage computer components without causing any signs of physical
damage. You must take extra care in handling 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 connectors by their ends.

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 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.

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 instal­lation or servicing. After installation or servicing, cover the system chassis
before plugging the power cord.

Battery:

• Danger of explosion if battery incorrectly replaced.

• Replace only with the same or equivalent type recommend by the manufac­turer.

• Dispose of used batteries according to local ordinance.

Introduction

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.

DDR3

DDR3 delivers increased system bandwidth and improved performance. It offers
peak data transfer rate of up to 32 Gb/s bandwidth. The advantages of DDR3
are its higher bandwidth and its increase in performance at a lower power than
DDR2.

Graphics

The integrated Intel HD graphics for graphics intensive applications delivers ex­ceptional 3D, 2D and video capabilities. It supports VGA and DVI interfaces.

DVI

DVI (Digital Visual Interface) is a form of video interface technology made to
maximize the quality of flat panel LCD monitors and modern video graphics
cards. Data is transmitted using the TMDS (Transition Minimized Differential Sig­naling) protocol, providing a digital signal from the PC’s graphics subsystem to
the display.

Audio

The Realtek ALC886 audio codec provides 5.1-channel High Definition audio out­put.

Serial ATA

Serial ATA is a storage interface that is compliant with SATA 1.0a specifica­tion. SATA 3.0 supports speed up to 6Gb/s while SATA 2.0 supports speed up to
3Gb/s. This improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s.

Gigabit LAN

The Realtek RTL8111DL PCI Express Gigabit controllers supports up to 1Gbps
data transmission.

1

13

Introduction

USB

The system board supports USB 2.0 and USB 1.1 ports. USB 1.1 supports 12Mb/
second bandwidth while USB 2.0 supports 480Mb/second bandwidth providing a
marked improvement in device transfer speeds between your computer and a
wide range of simultaneously accessible external Plug and Play peripherals.

Wake-On-LAN

This feature allows the network to remotely wake up a Soft Power Down (Soft­Off) 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.

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.

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.

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 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

1

14

Introduction

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.

Important:

The 5V_standby power source of your power supply must support
720mA.

Power Failure Recovery

When power returns after an AC power failure, you may choose to either power­on the system manually or let the system power-on automatically.

Hardware Installation

System Memory

Important:

Electrostatic discharge (ESD) can damage your system board, processor,
disk drives, add-in boards, 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 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.

Channel A

Channel B

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.

Features

• The four DIMM sockets are divided into 2 channels:

Channel A - DDR3_1 and DDR3_2
Channel B - DDR3_3 and DDR3_4

• Dual channel memory interface

• Maximum of 32GB system memory

17

2

Hardware Installation

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.

DIMMs of the same memory confi guration are
on different channels.

Single Channel

Dual Channel

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.

Important:

1. You can populate either Channel A or Channel B fi rst.

2. When installing a DIMM in Channel A or Channel B, always populate
the socket that is farthest the CPU. In this case, it will mean popu­lating DDR3-2 and/or DDR3-4 fi rst.

3. If you intend to use dual channel, the same rule applies - always
the socket farthest the CPU. Populate DDR3-2 and/or DDR3-4 fi rst;
not DDR3-2 and DDR3-3 and not DDR3-1 and DDR3-4.

The system board is equipped with a surface mount LGA 1155 socket. This sock­et is exclusively designed for installing a LGA 1155 packaged Intel CPU.

Important:

1. Before you proceed, make sure (1) the LGA 1155 socket comes with
a protective 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 1155 socket comes with the protective
cap.

Hardware Installation

Installing the Fan and Heat Sink

The CPU must be kept cool by using a CPU fan with heat sink. Without suffi cient
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

®

-certifi ed 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 ap-

ply 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 push­pins 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 such
that the CPU fan’s cable is
nearest the CPU fan con­nector.

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.

By default, the PS/2 port supports PS/2 keyboard only. If you intend to
connect a PS/2 mouse, you must set JP3 to 2-3 On. This will support
the auto-swap function allowing the system to auto-detect the PS/2 de­vice.

To allow the system to detect devices that may be incorrectly plugged to
the wrong port on the cable, set JP3 to 2-3 On. Setting JP3 to 2-3 On
will enable the auto-swap function allowing you to use the devices with­out having to replug the devices.
