You can guess that I've tried that already :p. I will try again but certainly it wont fix it.

EDIT

I tried even without backplate to make sure it is not preventing the lock from locking properly. Nope, even tried wiping the contact points with alcohol aswell, didnt change anything. 1st slot is x8 no matter what I try, even with another card. And when 3rd slot is x2, something must be wrong with the board.
