I'm having a severely hard time installing in my new x2 6400+ processor. The heatsink that it came with does NOT come with a small notch where you can put in a screwdriver to push down and clip onto the other side of the tab. I just don't see how its possible to do this with your fingers without breaking them or something else. It doesn't even budge. Is amd joking not to include this small notch? Not everyone is hercules. Any advice is appreciated on this. thank you.
