2.3 Central Processing Unit (CPU)
The motherboard comes with an AM3 socket designed for AMD ® Phenom™ II / Athlon™ II /
Sempron™ 100 Series Processors.
The AM3 socket has a different pinout from the 940-pin socket designed for the AMD
Opteron processor. Ensure that you use a CPU designed for the AM3 socket. The CPU fits
in only one correct orientation. DO NOT force the CPU into the socket to prevent bending
the connectors on the socket and damaging the CPU!
Ensure that all power cables are unplugged before installing the CPU.
2.3.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
Ensure that the socket lever is lifted up
to a 90º angle. Otherwise, the CPU will
not fit in completely.
2. Press the lever sideways to unlock the
socket, then lift it up to a 90º angle.
