2.3.2 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
2.3 Central Processing Unit (CPU)
2.3.1 Overview
The motherboard comes with a surface mount 939-pin Zero Insertion Force
(ZIF) socket designed for the AMD Athlon™ 64 and AMD Opteron™ 64
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 notched corner on
the CPU. This corner should match
a specific corner on the socket to
ensure correct installation.
