ASUS A T3N7A-I 1-1 Chapter 1 Product introduction If any of the items is damaged or missing, contact your retailer . Thank you for buying an ASUS ® A T3N7A-I motherboard! Before you start installing the motherboard, and hardware devices on it, check the items in your motherboard package. Refer to page ix for the list of accessories. 1.1 Before you proceed T ake 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 A TX 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. Onboard LED The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.
1-2 Chapter 1: Product introduction 1.2.2 Layout contents 1.2 Motherboard overview 1.2.1 Motherboard layout 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. Ensure that you install the motherboard into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis. Place this side towards the rear of the chassis. Connectors/Jumpers/Slots/LED Pa ge Connectors/Jumpers/Slots/LED Page 1.

Ensure that the CPU fan cable is connected to the onboard CPU_Fan connector . 1.4 System memory 1.4.1 Overview The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. The gure illustrates the location of the DDR2 DIMM sockets: Channel Sockets Channel A DIMM_A1 Channel B DIMM_B1
1-4 Chapter 1: Product introduction 1.4.2 Memory congurations Y ou may install 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMMs into the DIMM sockets. • Y ou 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 the single-channel operation. • Alwa ys inst all DIMMs wi th the same CA S la tency . For optimum com patibili ty , it is reco mmended tha t you ob tain me mory mo dule s from the same ven dor . • 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 3GB system memory if you are using a 32-bit Windows ® OS. - Install a 64-bit Windows ® OS when you want to install 4GB or more memory on the motherboard. • This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less. This motherboard supports up to 4GB on Windows ® XP Professional x64 and Windows ® Vista x64 editions. Y ou may install a maximum of 2GB DIMMs on each slot.

ASUS A T3N7A-I 1-7 1.5 Expansion slot In the future, you may need to install expansion cards. The following sub-sections describe the slot and the expansion cards that it supports. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.5.1 Installing an expansion card T o 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 rmly 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 . 1.5.2 Conguring an expansion card After installing the expansion card, congure it by adjusting the software settings. 1. T urn 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. 1.5.3 PCI slot The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specications.
1-8 Chapter 1: Product introduction 1.6 Jumpers 1. Clear RTC RAM (3-pin CLRTC) This jumper allows you to clear the Real T ime Clock (RTC) RAM in CMOS. Y ou 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. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery . T o erase the RTC RAM: 1. T urn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2. 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.

ASUS A T3N7A-I 1-1 1 1. A TX power connectors (24-pin EA TXPWR, 4-pin A TX12V) These connectors are for A TX power supply plugs. The power supply plugs are designed to t these connectors in only one orientation. Find the proper orientation and push down rmly until the connectors completely t. • We recommend that you use an A TX 12V Specication 2.0-compliant power supply unit (PSU) with a minimum of 400W power rating. This PSU type has 24-pin and 4-pin power plugs. • If you intend to use a PSU with 20-pin and 4-pin power plugs, ensure that the 20-pin power plug can provide at least 15 A on 12 V and that the PSU has a minimum power rating of 400W . The system may become unstable or may not boot up if the power is inadequate. • DO NOT forget to connect the 4-pin A TX 12V power plug. Otherwise, the system will not boot up. • We recommend that you use a PSU with higher power output when conguring a system with more power-consuming devices or when you intend to install additional devices. The system may become unstable or may not boot up if the power is inadequate. • If you are uncertain about the minimum power supply requirement for your system, refer to the Recommended Power Supply Wattage Calculator at http://support.asus. com/PowerSupplyCalculator/PSCalculator .aspx?SLanguage=en-us for details. 1.7.2 Internal connectors
