1.6 Central Processing Unit (CPU)
The motherboard comes with an AM2/AM2+ socket designed for AMD ® Socket
AM2+ Phenom™ FX / Phenom / Athlon™ 64 / Sempron™ processor or for Socket
AM2 Athlon 64 X2 / Athlon 64 FX / Athlon 64 / 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!
