Central 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!
