This chapter describes the motherboard features and the new technologies it supports.
1.1 Welcome! Thank you for buying an ASUS® A8V-X motherboard! 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.
1.3 Special features 1.3.1 Product highlights Latest processor and 64-bit computing technology The AMD Athlon™ 64FX, Athlon™ 64, Athlon™ 64 X2, and AMD Sempron™ desktop processors are based on AMDʼs 64-bit and 32-bit architecture, which represents the landmark introduction of the industryʼs first x8664 technology. These processors provide a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership and development. See page 1-9 for details.
Serial ATA 3Gb/s technology The motherboard supports the Serial ATA 3Gb/s technology through the Serial ATA interfaces. The Serial ATA II 3Gb/s specification provides twice the bandwidth of the current Serial ATA products with a host of new features, including Native Command Queuing (NCQ), and Power Management (PM) Implementation Algorithm. The Serial ATA allows for thinner, more flexible cables with lower pin count, reduced voltage requirement. See pages 1-25 for details.
Temperature, fan, and voltage monitoring The CPU temperature is monitored by the ASIC (integrated in the ITE Super I/O) to prevent overheating and damage. The system fan rotations per minute (RPM) is monitored for timely failure detection. The ASIC monitors the voltage levels to ensure stable supply of current for critical components. See section “2.5.4 Hardware Monitor” on page 2-31. 1.3.
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 to 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 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components. 1.5.1 Placement direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation.

1.6 Central Processing Unit (CPU) 1.6.1 Overview The motherboard comes with a surface mount 939-pin Zero Insertion Force (ZIF) socket designed for the AMD Athlon™ 64FX, AMD Athlon™ 64 X2, AMD Athlon 64™ or AMD Sempron™ processor. The 128-bit-wide data paths of these processors can run applications faster than processors with only 32-bit or 64-bit wide data paths. Take note of the marked corner (with gold triangle) on the CPU.
2. Unlock the socket by pressing the lever sideways, then lift it up to a 90°-100° angle. Make sure that the socket lever is lifted up to 90°-100° angle, otherwise the CPU does not fit in completely. 3. Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle. 4. Carefully insert the CPU into the socket until it fits in place. The CPU fits only in one correct orientation.
1.6.3 Installing the heatsink and fan The AMD Athlon™ 64, AMD Athlon™ 64FX or AMD Athlon™ 64 X2 processors require a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. Make sure that you use only qualified heatsink and fan assembly. Follow these steps to install the CPU heatsink and fan. 1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits properly on the retention module base.
2. Attach one end of the retention bracket to the retention module base. 1 2 4 3 3. 5 Align the other end of the retention bracket (near the retention bracket lock) to the retention module base. A clicking sound denotes that the retention bracket is in place. Make sure that the fan and heatsink assembly perfectly fits the retention mechanism module base, otherwise you cannot snap the retention bracket in place. 4.
1.7 System memory 1.7.1 Overview The motherboard comes with four 184-pin Double Data Rate (DDR) Dual Inline Memory Modules (DIMM) sockets.

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. 1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket. 2 DDR DIMM notch 1 1 Unlocked retaining clip A DDR DIMM is keyed with a notch so that it fits in only one direction.
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. We recommended to install the memory modules first before installing an AGP 8X card. 1.8.1 Installing an expansion card To install an expansion card: 1.
