The red warning LED lights up when you installed two graphics card but did not connect the ASUS EZ Plug™. The illustration below shows the location of the onboard LEDs.

2.1 Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

• Make sure that your power supply unit (PSU) can provide at least the minimum power required by your system. See “7. ATX power connectors” on page 2-25 for details.

• 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.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

2.3 .2 Ins ta ll ing t he CP U

To install a CPU:

1. Locate the CPU socket on the motherboard.

2.3 Central Processing Unit (CPU)

2.3 .1 Ove rv ie w

The motherboard comes with a surface mount 939-pin Zero Insertion Force (ZIF) socket designed for the AMD Athlon™ 64FX, AMD Athlon™ 64 or AMD Athlon™ 64X2 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.

Before installing the CPU, make sure that the socket box is facing towards you and the load lever is on your left.

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.
