1.6 Central Processing Unit (CPU)
1.6.1 Overview
The motherboard provides a Socket A for CPU installation. Each AMD CPU has a
“marked” corner. This corner is usually indicated with a notch, and/or a golden
square or triangle. Refer to this indicator while orienting the CPU. A fan and
heatsink should be attached to the CPU to prevent overheating.
1.6.2 Installing the CPU
Follow these steps to install a CPU:
1. Locate the Socket 462 and open it by
pulling the lever gently sideways
away from the socket. Then lift the
lever upwards. The socket lever
must be fully opened (90 to 100
degrees).
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.
Golden corner
This motherboard does not support AMD processors with less than 1GHz core
speed.
