This chapter describes the motherboard features and the new technologies it supports.
1.1 Welcome! Thank you for buying an ASUS® M2N-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.
AMD Cool ‘n’ Quiet Technology The motherboard supports the AMD Cool ‘n’ Quiet Technology, which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet operating environment. NVIDIA ® nForce™ 520 MCP chipsets The NVIDIA® nForce™ 520 media and communications processor (MCP) builds on the award-winning single-chip, scalable architecture of the NVIDIA nForce MCP.
High Definition Audio The onboard 6-channel High Definition audio CODEC enables high-quality Realtek ALC883 audio CODEC, which automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection. 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 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 1.5.1 Motherboard layout 19.3cm(7.6in) PS/2KBMS T: Mouse B: Keyboard CPU_FAN PS2_USBPW1- USB LAN_USB12 EATXPWR 30.5cm(12.
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 can damage the motherboard.
1.6 Central Processing Unit (CPU) The motherboard comes with a 940-pin AM2 socket designed for the AMD Athlon™ 64 X2/Athlon™ 64/Athlon™ FX/Sempron™ processor. The AM2 socket has a different pinout from the 940-pin socket designed for the AMD Opteron™ processor. Make sure you use a CPU is designed for the AM2 socket. The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU! 1.6.
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. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU! 5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.
1.6.2 Installing the heatsink and fan The AMD Athlon™ 64 X2/Athlon™ 64/Athlon™ FX/Sempron™ processor 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. 3. 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 Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket. 12 Pins DIMM_A1 DIMM_B1 The figure illustrates the location of the DDR2 DIMM sockets: 112 Pins M2N-X M2N-X 240-pin DDR2 DIMM Sockets 1.7.

9. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V) These connectors are for an ATX power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. • We recommend that you use an ATX 12 V Specification 2.0‑compliant power supply unit (PSU) with a minimum of 300 W power rating. This PSU type has 24-pin and 4-pin power plugs.
10. System panel connector (20-1 pin F_PANEL) This connector supports several chassis-mounted functions. PLED+ PLEDPWR GND PWR LED PWR BTN M2N-X IDELED+ IDELEDGround Reset F_PANEL HD LED RESET M2N-X System Panel Connector • System power LED (2-pin PWRLED) This 2-pin connector is for the system power LED.
