Central Processing Unit (CPU)

The motherboard comes with an AM2+ / AM2 socket designed for AMD
AM2 Phenom™ FX / Phenom / Athlon™ / Sempron™ processor
The AM2/AM2+ socket has a different pinout from the 940-pin socket designed
for the AMD Opteron™ processor. Ensure that you use a CPU that is designed
for the AM2/AM2+ 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!
