2.3 Central Processing Unit (CPU)
2.3.1 Overview
The motherboard comes with a surface mount 940-pin Zero Insertion
Force (ZIF) socket designed for the AMD Athlon™ 64 FX and AMD
Opteron™ processors.
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.
Take note of the marked corner (with
gold triangle) on the CPU. This mark
should match a specific corner on the
socket to ensure correct installation.

2.3.2 Installing the CPU
Follow these steps to install a CPU.
1. Locate the 940-pin ZIF socket on the motherboard.

2. Unlock the socket by pressing the
lever sideways, then lift it up to a
90°-100° angle.
Socket Lever
Make sure that the socket lever is lifted up to 90°-100° angle,
otherwise the CPU does not fit in completely.
3. Position the CPU above the
socket such that the CPU corner
with the gold triangle matches the
socket corner with a small
triangle.
4. Carefully insert the CPU into the
socket until it fits in place.
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!
