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 754-pin surface mount, Zero Insertion Force (ZIF) socket that supports 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. See page 1-10.
PCI Express™ interface The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point-to-point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 1-22 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 1-26 and 1-30 for details. 1.3.2 ASUS Proactive features AI NET 2 AI NET 2 is a BIOS-based diagnostic tool that detects and reports Ethernet cable faults and shorts.
ASUS Multi-language BIOS The multi-language BIOS allows you to select the language of your choice from the available options. The localized BIOS menus allow you to configure easier and faster. Visit the ASUS website for information on the supported languages. See page 2-16 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. See page 2-8 for details.
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.

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. 1.6.2 Gold triangle Installling the CPU To install a CPU: 1. Locate the CPU socket on the motherboard. USB 2.
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. Gold triangle 5. When the CPU is in place, push down the socket lever to secure the CPU.
1.6.3 Installing the heatsink and fan The AMD Athlon™ 64FX or AMD Athlon 64™ 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.
3. When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

If you installed Serial ATA hard disk drives, you can create RAID 0, RAID 1, RAID 1+0, or JBOD configuration that spans across the Parallel ATA drives. Refer to Chapter 5 for details on how to set up RAID configurations.
4. CPU, Chassis and Power fan connectors (3-pin CPU_FAN, CHA2_FAN, PWR_FAN, CHIP_FAN) The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.) or a total of 1 A ~ 3.48 A (41.76 W max.) at +12 V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components.
