This chapter lists the hardware setup procedures that you have to perform when installing system components. It includes description of the jumpers and connectors on the motherboard.
1.1 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.
1.2 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Refer to the chassis documentation before installing the motherboard. 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. 1.2.

1.3 Central Processing Unit (CPU) The motherboard comes with a surface mount 939-pin Zero Insertion Force (ZIF) socket designed for the AMD Athlon™ 64FX or AMD Athlon™ 64 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. This mark should match a specific corner on the socket to ensure correct installation. Gold triangle 1.3.
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 Small triangle The CPU fits only in one correct orientation.
1.3.2 Installing the heatsink and fan The AMD Athlon™ 64FX or AMD Athlon™ 64 processor requires 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. 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. 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.
5. When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. GND +12V Rotation CPU_FAN A8N-SLI ® A8N-SLI CPU fan connector Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.
