Central Processing Unit (CPU)

The motherboard comes with an AMD
Phenom™ II / Athlon™ II / Sempron™ 100 Series processors.
The AM3 socket has a different pinout from the AM2+/AM2 socket. Ensure
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!
