2. Central Processing Unit (CPU)
The motherboard provides a Socket A (462) for CPU installation. AMD processors
offer gigahertz speeds to support all latest computing platforms and applications.
The A7N8X-LA supports AMD Athlon™/Athlon XP™ 3200+ processors. This
motherboard supports 400/333/266MHz front side bus (FSB), and allows data
transfers of up to 2.7GB/s with PC2700 DDR.
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 a heatsink should be attached to the CPU to prevent overheating.

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 fits only in one correct orientation. DO NOT force the CPU into the
socket to prevent bending the pins and damaging the CPU!
