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.

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 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 exceptional 3D, 2D and video capabilities. It supports VGA and DVI interfaces.
PCI Express
PCI Express is a high bandwidth I/O infrastructure that possesses the ability to
scale speeds by forming multiple lanes. 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.
Audio
The Realtek ALC262 audio codec provides 2-channel High Definition audio output.
Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification.
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 support up to 1Gbps data
transmission.
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.

Introduction
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
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.

14
Introduction
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.

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. If you intend to use dual channel, populate DDR3_1 and DDR3_2
the same rule applies - always the socket farthest the CPU.

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.

Power-on Select
JP8 is used to select the method of powering on the system. If you want the
system to power-on whenever AC power comes in, set JP8 pins 2 and 3 to On. If
you want to use the power button, set pins 1 and 2 to On.
When using the JP8 “Power On” feature to power the system back on after a
power failure occurs, the system may not power on if the power lost is resumed
within 5 seconds (power fl icker).
Note:
In order to ensure that power is resumed after a power failure that recovers within a 5 second period, JP8 must be set to pins 2-3 and the
“AC Power Lose” in CMOS is set to “On”.
