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 dis-

charge can damage computer components without causing any signs of physical

damage. You must take extra care in handling them to ensure against electro-

static 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 compo-

nents, 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 instal-

lation 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 manufac-

turer.

• Dispose of used batteries according to local ordinance.

Introduction

Features

Watchdog Timer

The Watchdog Timer function allows your application to regularly “clear” the sys-

tem 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 21 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 ex-

ceptional 3D, 2D and video capabilities. It supports HDMI and 2 DVI-I 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 Sig-

naling) protocol, providing a digital signal from the PC’s graphics subsystem to

the display.

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 trans-

fer rate of 1 Gigabyte per second. The PCI Express architecture also provides a

high performance graphics infrastructure by enhancing the capability of a x16 PCI

Express lane to provide 8 Gigabytes per second transfer rate.

Intel Active Management Technology (AMT)

Intel Active Management Technology (Intel

®

AMT) allows remote access and man-

agement of networked systems even while PCs are powered off, remotely repair

systems after OS failures and has the capability to remotely update all systems

with the latest security software.

Audio

The Realtek ALC886 audio codec provides 5.1-channel High Definition audio out-

put.

Introduction

Serial ATA

Serial ATA is a storage interface that is compliant with SATA 1.0a specifica-

tion. 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. The board supports RAID 0/1/5/10.

Gigabit LAN

The Intel WG82579LM PHY and Intel WG82574L PCI Express Gigabit controllers

support up to 1Gbps data transmission.

USB

The system board supports the new USB 3.0. It is capable of running at a maxi-

mum transmission 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 re-

quired for data transmission, reduces power consumption, and is backward com-

patible 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.

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 inter-

rupt.

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 sys-

tem 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.

14

Introduction

RTC Timer

The RTC installed on the system board allows your system to automatically pow-

er-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 Manage-

ment 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.

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 power-

on the system manually or let the system power-on automatically.

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 pro-

tection.

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 com-

pletely 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 popu-

lating 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.

CPU

The system board is equipped with a surface mount LGA 1155 socket. This sock-

et 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.
