Make sure that the socket lever is lifted up to a 90º angle; otherwise, the CPU
will not fit in completely.
2. Unlock the socket by pressing the
lever sideways, then lift it up to a
90º angle.

The AM2+/AM2 socket has a different pinout from the 940-pin socket designed
for the AMD Opteron processor. Make sure you use a CPU 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!
