1.4Central Processing Unit (CPU)

This motherboard comes with an AM3+ socket designed for FX™ / Phenom™ II / Athlon™ II / Sempron™ 100 series processors.

The AM3+ socket has a different pinout from the AM2+/AM2 socket. 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 pins and damaging the CPU!
