ASUS A7V400-MX motherboard user guide 1-7 1 .6 Central Processing Unit (CPU) 1.6.1 Overview The motherboard provides a Socket A for CPU installation. Each AMD CPU has a “ marked” corner . This corner is usually indicated with a notch, and/or a golden square or triangle. Refer to this indicator while orienting the CPU. A fan and heatsink should be attached to the CPU to prevent overheating. 1.6.2 Installing the CPU Follow these steps to install a CPU: 1. Locate the Socket 462 and open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees). 2. Insert the CPU with the correct orientation. The notched or golden corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge. The CPU should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins. Golden corner This motherboard does not support AMD processors with less than 1GHz core speed. A7V400-MX ® A7V400-MX Socket 462 AMD ™ CPU CPU NOTCH LOCK CPU NOTCH TO INNER CORNER LEVER

Unlock a DIMM socket by pressing the retaining clips outward. 3. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket. 1.7.4 Removing a DIMM Follow these steps to remove a DIMM. 1. Simultaneously press the retaining clips outward to unlock the DIMM. 4. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated. 2. Remove the DIMM from the socket. Unlocked Retaining Clip DDR DIMM notch Locked Retaining Clip Make sure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components. A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM. Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force.
1-10 Chapter 1: Product introduction 1 .8 Expansion slots In the future, you may need to install expansion cards. The following sections describe the motherboard slots and the expansion cards that they support. 1.8.1 Installing an expansion card Follow these steps 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 . 1.8.2 Configuring an expansion card After installing the expansion card, configure the card 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. Refer to the tables on the next page. 3. Install the software drivers for the expansion card. Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.

ASUS A7V400-MX motherboard user guide 1-13 1 .9 Switch and jumpers 1. CPU external frequency selection (DSW Switches 1-5) The motherboard frequency is adjusted through the DIP switches. The white block represents the switch position. The illustration below shows the ON and OFF positions of the switches. The option to set the CPU core bus frequency multiple is available only on unlocked CPUs. If you are using a locked CPU, setting the switches does not produce any effect. Set the CPU frequency only to the recommended settings. Frequencies other than the recommended CPU bus frequencies are not guaranteed to be stable. The default CPU external frequency is 100MHz. If your CPU supports 200/166/ 133 MHz external frequency , adjust the DSW settings before installing the motherboard to the chassis. The DSW switch tells the clock generator what frequency to send the CPU. This allows the selection of the CPU ’s external frequency (or bus clock). The bus clock multiplied by the frequency multiple equals the CPU ’s internal frequency (the advertised CPU speed).

1-14 Chapter 1: Product introduction 2. USB device wake-up (3-pin USBPWR12, USBPWR34, USBPWR56) Set these jumpers to 5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to 5VSB to wake up from S3 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). Both jumpers are set to pins 1-2 ( 5V) by default because not all computers have the appropriate power supply to support this feature. The USBPWR12 and USBPWR34 jumpers are for the rear USB ports. USBPWR56 is for the internal USB connector . • The USB device wake-up feature requires a power supply that can provide 500mA on the 5VSB lead for each USB port. Otherwise, the system does not power up. • The total current consumed must NOT exceed the power supply capability ( 5VSB) whether under normal condition or in sleep mode.

2-6 Chapter 2: BIOS information 2.3 BIOS Setup progr am This motherboard supports a programmable Low Pin Count (LPC) chip that you can update using the provided utility described in section “2.1 Managing and updating your BIOS. ” Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to “Run Setup ”. This section explains how to configure your system using this utility . Even if you are not prompted to use the Setup program, you may want to change the configuration of your computer in the future. For example, you may want to enable the security password feature or make changes to the power management settings. This requires you to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the LPC chip. The LPC chip on the motherboard stores the Setup utility . When you start up the computer , the system provides you with the opportunity to run this program. Press <Delete> during the Power-On Self T est (POST) to enter the Setup utility , otherwise, POST continues with its test routines. If you wish to enter Setup after POST , restart the system by pressing <Ctrl> <Alt> <Delete>, or by pressing the reset button on the system chassis. Y ou can also restart by turning the system off and then back on. Do this last option only if the first two failed. The Setup program is designed to make it as easy to use as possible. It is a menu- driven program, which means you can scroll through the various sub-menus and make your selections among the predetermined choices. 2.2 BIOS beep codes When you turn the power on and the system runs POST (Power On Self T ests), you will hear BIOS beeps. Refer to the following table for the meaning of the beeps. Award BIOS beep codes Beep Meaning One short beep when No error during POST displaying logo Long beeps in an endless loop No DRAM installed or detected One long beep followed by V ideo card not found or video card three short beeps memory bad High frequency beeps when CPU overheated; system is working System running at a lower frequency
