1.8 Central Processing Unit (CPU)
The motherboard provides a Socket A (462) for CPU installation. The
A7N8X-VM/400 supports Athlon™ XP processors with “QuantiSpeed” data
processing, large data caches, 3D enhancements and 400/333/266MHz bus
speeds. AMD Athlon™ XP processors offer gigahertz speeds to support all the
latest computing platforms and applications.
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.

This motherboard does not support Athlon™, Duron™, and other AMD
processors with less than 1GHz core speed.
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.
