This chapter describes the motherboard features and the new technologies it supports.
1.1 Welcome! Thank you for buying an ASUS® M2S-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 technology The motherboard comes with a 940-pin AM2 socket that supports AMD Athlon™ 64 FX/AMD Athlon™ 64 X2/AMD Athlon™ 64/AMD Sempron™ processors. With an integrated low-latency high-bandwidth memory controller and a highly scalable HyperTransport™ technology-based system bus, the motherboard provides a powerful platform for your diverse computing needs, increased office productivity, and enhanced digital media experience.
1.3.2 Unique ASUS features CrashFree BIOS 3 The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB flash disk containing the BIOS file. This utility saves users the cost and hassle of buying a replacement BIOS chip. C.P.R. (CPU Parameter Recall) The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the BIOS default settings in case the system hangs due to overclocking. When the system hangs due to overclocking, C.P.R.
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.

1.5.2 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 six (6) screws into the holes indicated by circles to secure the motherboard to the chassis. Do not overtighten the screws! Doing so may damage the motherboard.
1.6 Central Processing Unit (CPU) 1.6.1 Overview The motherboard comes with a surface mount 940-pin AM2 socket designed for the AMD Athlon™ 64, AMD Athlon™ 64 X2, AMD Athlon™ 64 FX, and AMD Sempron™ Processors. Take note of the marked corner (with gold triangle) on the CPU. This mark should match a specific corner on the socket to ensure correct installation. Gold triangle 1.6.2 Installling the CPU To install a CPU: 1. Locate the CPU socket on the motherboard.
2. Unlock the socket by pressing the lever sideways, then lift it up to a 90°‑100° angle. Socket Lever 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. Small triangle Gold triangle The CPU fits only in one correct orientation.
1.6.3 Installing the heatsink and fan The AMD Athlon™ 64, AMD Athlon™ 64 X2, AMD Athlon™ 64 FX, or AMD Sempron™ 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.
