Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
• When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
• Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
• Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
• Ensure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
• If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.

Motherboard overview
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.
• Unplug the power cord before installing or removing the motherboard. Failure to do so
can cause you physical injury and damage to motherboard components.

1-2 Chapter 1: Product introduction
CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN )
Connect the fan cables to the fan connectors on the motherboard, ensuring that
the black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside
the system may damage the motherboard components. These are not jumpers! Do not
place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan
of maximum 1A (12 W) fan power.
SATA power connector (15-pin SATA_PWRCON)
This connector is for the SATA power cable. The power cable plug is designed to
t this connector in only one orientation. Find the proper orientation and push down
rmly until the connector completely t. To provide power to your SATA device,
connect the SATA power cable to this connector
USB 2.0 connectors (USBE1~5)
Connect the USB module cable to these connectors, then install the module to a
slot opening at the back of the system chassis. These USB connectors comply with
USB 2.0 specications and support up to 480Mbps connection speed.
Serial ATA 6.0Gb/s connectors (SATA6G_1/2)
These connectors connect to Serial ATA 6.0 Gb/s hard disk drives via Serial ATA
6.0 Gb/s signal cables.
When using hot-plug and NCQ, set the SATA Mode Selection item in the BIOS to
[AHCI].
LCD panel monitor switch header (2-pin PANEL_SW)
This 2-pin header is for connecting a monitor switch that can turn off the LCD panel
display backlight.
System panel connector (10-1 pin PANEL)
This connector supports several chassis-mounted functions.
Speaker connector (4-pin SPEAKER)
This 4-pin connector is for the chassis-mounted system warning speaker. The
speaker allows you to hear system beeps and warnings.

sockets.
TPM connector (14-1 pin TPM)
This connector supports a Trusted Platform Module (TPM) system, which can
securely store keys, digital certicates, passwords and data. A TPM system also
helps enhance network security, protects digital identities, and ensures platform
integrity.
DMIC connector (4-pin DMIC)
The DMIC connector is for connecting the digital microphone module used in All-in-
One chassis.
Chassis intrusion header (4-1 pin CHASSIS)
This header is for a chassis-mounted intrusion detection sensor or switch. Connect
one end of the chassis intrusion sensor or switch cable to this header. The chassis
intrusion sensor or switch sends a high-level signal to this header when a chassis
component is removed or replaced. The signal is then generated as a chassis
intrusion event.
By default, the pin labeled “Chassis Signal” and “Ground” are shorted with a jumper
cap. Remove the jumper caps only when you intend to use the chassis intrusion
detection feature.
Front panel audio connector (10-1 pin AAFP)
This connector is for a chassis-mounted front panel audio I/O module that supports
either HD Audio or legacy AC`97 audio standard. Connect one end of the front
panel audio I/O module cable to this connector

1-4 Chapter 1: Product introduction
• We recommend that you connect a high-denition front panel audio module to this
connector to avail of the motherboard’s high-denition audio capability.
• If you want to connect a high-denition front panel audio module to this connector,
set the Front Panel Type item in the BIOS setup to [HD Audio]. If you want to
connect an AC’97 front panel audio module to this connector, set the item to
[AC97]. By default, this connector is set to [HD Audio].
Internal stereo speaker header (4-pin SPK_OUT)
The internal mono speaker header allows connection to an internal, low-power
speaker for basic system sound capability. The subsystem is capable of driving a
speaker load of 4 Ohms at 3 Watts (rms).
Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the CMOS RTC RAM data of
the system setup information such as date, time, and system
passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two
pins.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and
enter BIOS setup to re-enter data.
If the steps above do not help, remove the onboard battery and short the
two pins again to clear the CMOS RTC RAM data. After clearing the CMOS,
reinstall the battery.
Serial port connector (10-1 pin COM4)
Connect the serial port module cable to this connector, then install the module to a
slot opening at the back of the system chassis.
mSATA/mPCIe combo slot (MSATA_MPCIE)
This slot allows you to install a full length mSATA or mini-PCIe card, providing you
with expandability and connectivity solutions for an optimal system performance.
• mSATA shares the same slot with the full-length mini-PCIe card.
• mSATA shares the same bandwidth with SATA6G_2 slot. When a device is
installed on the SATA6G_2 slot, the mSATA device is disabled.

When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI

Central Processing Unit (CPU)
The motherboard comes with an onboard Intel®Celeron®Dual-core processor.
System memory
Overview
This motherboard comes with two Double Data Rate 3 (DDR3) Small Outline Dual Inline
Memory Module (SO-DIMM) sockets. The gure illustrates the location of the DDR3 DIMM
sockets:
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
• You may install varying memory sizes in Channel A and Channel B. The system
maps the total size of the lower-sized channel for the dual-channel conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
• Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code
(D/C) from the same vendor. Check with the vendor to get the correct memory
modules.
• Always install a DIMM into the DIMM_A1 slot for the motherboard to work properly.
• This motherboard supports 1.35V DDR3L and 1.5V DDR3 DIMMs.
• Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
- Use a maximum of 3 GB system memory if you are using a 32-bit Windows®OS.
- Install a 64-bit Windows® OS if you want to install 4GB or more on the
motherboard.
- For more details, refer to the Microsoft®support site at http://support.microsoft.
