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 fix it by yourself. Contact a qualified service technician or your retailer.

Operation safety

•Before installing the motherboard and adding devices on it, carefully read all the manuals that came with the package.

•Before using the product, ensure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately.

1.1Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

• 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.

•Hold components by the edges to avoid touching the ICs on them.

•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

•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.

1.2Motherboard overview

Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.

Ensure that you unplug the power cord before installing or removing the motherboard.

Failure to do so can cause you physical injury and damage motherboard components.

1.2.1Placement direction

When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.

1.2.2Screw holes

Place four screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not overtighten the screws! Doing so can damage the motherboard.

When you install only one memory module, install it to DIMM_A1 slot.

1-4	Chapter 1: Product introduction

1.4.2Memory configurations

You may install 1GB, 2GB, 4GB, and 8GB unbuffered non ECC DDR3 U-DIMMs into the DIMM sockets.

•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 configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.

•Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.

•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:

-Install a maximum of 3GB system memory if you are using a 32-bit Windows® OS.

-Use a 64-bit Windows® OS if you want to install 4GB or more memory on the motherboard.

-For more details, refer to the Microsoft® support site at http://support.microsoft. com/kb/929605/en-us.

•This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.

• The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, refer to section 2.5 Ai Tweaker menu for manual memory frequency adjustment.

•For system stability, use a more efficient memory cooling system to support a full memory load (2 DIMMs) or overclocking condition.

•Refer to www.asus.com for the latest Memory QVL (Qualified Vendors List).

1.5Expansion slots

In the future, you may need to install expansion cards. The following sub sections describe the slots and the expansion cards that they support.

Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.

1.5.1Installing an expansion card

To install an expansion card:

1.Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card.

2.Remove the system unit cover (if your motherboard is already installed in a chassis).

3.Remove the bracket opposite the slot that you intend to use. Keep the screw for later use.

4.Align the card connector with the slot and press firmly until the card is completely seated on the slot.

5.Secure the card to the chassis with the screw you removed earlier.

6.Replace the system cover.

1.5.2Configuring an expansion card

After installing the expansion card, configure it by adjusting the software settings.

1.Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for information on BIOS setup.

2.Assign an IRQ to the card.

3.Install the software drivers for the expansion card.

1.5.3mini PCIe slot

This mini PCIe slot supports a half length mini PCIe module.

1.5.4PCI Express 2.0 x4 slot (@x1 mode)

This motherboard supports PCI Express 2.0 x4 network cards, SCSI cards, and other cards that comply with the PCI Express specifications.

1.Clear RTC RAM (2-pin CLCMOS)

This header allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.

N3150I-C / N3050I-C Clear RTC RAM

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 reenter 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.

•You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut down and reboot the system, then the BIOS automatically resets parameter settings to default values.

3.Chassis intrusion connector (4-1 pin CHASSIS)

This connector is for a chassis-mounted intrusion detection sensor or switch.

Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced. The signal is then generated as a chassis intrusion event.

By default, the pins labeled “Intruder” are shorted with a jumper cap. Remove the jumper caps only when you intend to use the chassis intrusion detection feature.
