1.6.1Overview

The motherboard has a Socket A for installation. The AMD Athlon™/Sempron™ /Duron™ CPU has a “marked” corner. This corner is usually indicated with a notch, and/or a golden square or triangle. Refer to this indicator when orienting the CPU. A fan and heatsink should be installed on top of the CPU to prevent overheating.

Do not use processors with core speeds of less than 1GHz.

1.6.2Installing the CPU

Golden corner

Follow these steps to install a CPU:

1.Locate the CPU socket. Open the socket by pulling the lever gently sideways away from the socket, then lift the lever upwards to a 90 to 100-degree angle.

2.Insert the CPU with the correct orientation . The notched or golden corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge.

The CPU should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins.
