This chapter describes the motherboard features and the new technologies it supports.
1.1 Welcome! Thank you for buying an ASUS® A8V-XE 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 x86-64 technology. These processors provide a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership and development. See page 1-8 for details.
USB 2.0 technology The motherboard implements the Universal Serial Bus (USB) 2.0 specification, dramatically increasing the connection speed from the 12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1. See pages 1-20 and 1-26 for details. S/PDIF-out on Back I/O Port This motherboard provides convenient connectivity to external home theater audio systems via an S/PDIF-out (SONY-PHILIPS Digital Interface) jack.
1.4 Before you proceed Take note of the following precautions before you install components into the system. • 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 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™ ,AMD Athlon 64 X2 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™ 64FX, Athlon™ 64X2, AMD Athlon 64™ or AMD Sempron™ processor require a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. 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. • The retention module base is already installed on the motherboard upon purchase.
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 two Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets. DIMM_B2 DIMM_B1 DIMM_A2 104 Pins DIMM_A1 The following figure illustrates the location of the sockets: 80 Pins A8V-XE R A8V-XE 184-pin DDR DIMM Sockets Channel 1.7.
