1.6 Central Processing Unit (CPU)

The motherboard comes with an AM2+ / AM2 socket designed for AMD®

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 you use a CPU designed for the

AM2+/AM2 socket. The CPU ts 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!

lever sideways, then lift it up to a
