I am having major problems with installing the heatsink on my ATHLON 64 939 3000.
The processor goes in nicely, but when I tried to install the heatsink, it took a tremendous amount of force to get it to clip onto both tabs. When I finally got it clipped in, it was impossible to rotate the plastic safety arm. So, the heat sink is clipped in but I can't engage the plastic retention arm.
Did I do something incorrectly? Its not clear how this thing is supposed to attach!
I have not powered it up yet, I would prefer to make sure everything is secure before applying power. Any tips?
