Your sample board is by Asus and their retention module seems to differ considerably from the one Gigabyte is using. I have no doubt that mounting the heatsink works fine on an Asus board, as demonstrated on your photos.

I did follow the procedure shown on your images, as it's the only reasonable way to accomplish the mounting procedure, yet step three is impossible unless you modify the side clip's position. Only then will the mounting process work as illustrated (and described). The heatsink sits reasonably tight on the CPU and there are no abnormally high temperatures, so to me, this change was the right thing to do.

You may have to aquire a recent Gigabyte board for AMD CPUs to see the difference with your own eyes. Unfortunately, Hamburg is not in my immediate neighbourhood, else I'd offer to use my machine as live test case for studying ;-)
