This chapter describes the motherboard features and the new technologies it supports.
1.1 Welcome! T h a n k y o u f o r b u y i n g a n A S U S® A 7 V 4 0 0 - M X S E m o t h e r b o a r d ! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
DDR memory support Employing the Double Data Rate (DDR) memory technology, the motherboard supports up to 2 GB of system memory using DDR 333/266/ 200 DIMMs. The fast 333 MHz memory bus delivers the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page 1-9 for details. Serial ATA technology The motherboard supports the Serial ATA technology through the Serial ATA connectors and the VIA VT8237R.
1.3.2 Innovative ASUS features CrashFree BIOS This feature allows you to restore the original BIOS data from a floppy disk (with the original BIOS file and the AwardBIOS Flash Utility) in case the BIOS file gets corrupted. This utility eliminates the need to buy a replacement ROM chip. See page 2-4 for details. ASUS EZ Flash BIOS With the ASUS EZ Flash, you can easily update the system BIOS even before loading the operating system. No need to use a DOS-based utility or boot from a floppy disk.
1.4 Before 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. • Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity • Hold components by the edges to avoid touching the ICs on them.

1.5.2 Placement direction When installing the motherboard, make sure 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. 1.5.3 Screw holes Place eight (8) 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.
1.6 Central Processing Unit (CPU) 1.6.1 Overview The motherboard has a Socket A for installation. The Athlon™/Sempron™ CPU has a “marked” corner. This corner is usually indicated with a notch, and/or a golden square or triangle. Refer to this indicator when orienting the CPU. A fan and heatsink should be installed on top of the CPU to prevent overheating. This motherboard does not support AMD processors with less than 1 GHz core speed.
1.7 System memory 1.7.1 Overview DIMM2 A7V400-MX SE 184-pin DDR DIMM sockets DIMM1 A7V400-MX SE 80 Pins 104 Pins The motherboard has two Double Data Rate (DDR) DIMM sockets that support up to 2 GB unbuffered non-ECC DDR400*/333/266/200 DDR SDRAM DIMMs. Each DIMM socket is double-sided. * You can install a DDR400 DIMM(s) on the slot(s). However, a DDR400 DIMM may only run at speeds of up to 333 MHz (DDR333). 1.7.

1.7.3 Installing a DIMM 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. Follow these steps to install a DIMM. 1. Locate the DIMM sockets in the motherboard. 2. 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.
1.8 Expansion 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. 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. 1.8.1 Installing an expansion card To install an expansion card: 1.

2. Clear RTC RAM (CLRTC) This jumper 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. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Remove the onboard battery. 3. Move the jumper cap from pins 2-3 (default) to pins 1-2.
3. USB device wake-up (3-pin USBPWR12, USBPWR34, USBPWR56, USBPWR78) 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 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).
