Socket lever

Ensure that the socket lever is lifted up to a 90°-100° angle; otherwise, the CPU will not t

in completely.

3. Position the CPU above the socket such that the CPU

corner with the gold triangle matches the socket corner

with a small triangle.

4. Carefully insert the CPU into the socket until it ts in place.

The CPU ts only in one correct orientation.

DO NOT force the CPU into the socket to

prevent bending the pins and damaging the

CPU!

a CPU designed for the AM3 socket.
