I wouldn't touch it to try it on your friend's motherboard. Handle your pc components as little as possible. Trying it on his board won't accomplish much, unless he wants to sell it to you. Electronic components are sensitive to esd (static discharge), and should only be removed for replacement. If it works on your board, forget about overclocking. The performance difference is only a few frames per second, not worth the risk of damaging the cpu or pins in the socket.
