Central Processing Unit (CPU)

The motherboard comes with a 940-pin AM2+ socket designed for AMD

®

Phenom™FX / Phenom™ / Athlon™ / Sempron™ processors.

The AM2+ socket has a different pinout from the 940-pin socket designed for

the AMD Opteron™ processor. Ensure that you use a CPU 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 pins and damaging the CPU!

Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

2. Unlock the socket by pressing the

lever sideways, then lift it up to a

90°-100° angle.

Ensure that the socket lever is lifted up to 90°-100° angle, otherwise the CPU

does not fit in completely.
