I just got my athlon tbird 900, and kt7-raid mobo...I got the proc in the socket, now I need to put on that giant heatsink that came with it. I got the first side on properly, but when I push down the other side of the latch, the hook doesn't reach the lug on the other side of the socket! what should I do? and should pushing down the other side of the latch require lots of pressure?
