In Figure 10 we can see the installation hardware for sockets 775 and 1156. With socket 775 you must use the black backplate on the left and the frame on the right. With socket 1156, however, the backplate is not used and the frame is attached to the motherboard using the black nuts shown at the bottom of Figure 10. In both cases you must have access to the solder side of the motherboard.
