1.6 Central Processing Unit (CPU)
The motherboard comes with a 940-pin AM2 socket designed for the AMD
Athlon™ 64 X2/Athlon™ 64/Athlon™ FX/Sempron™ processor.
The AM2 socket has a different pinout from the 940-pin socket designed
for the AMD Opteron™ processor. Make sure you use a CPU is designed
for the 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!
