The switch is just a dual bios feature, all of the cards have them. Only the cards with the reference PCB (hence the AMD logo) have the change to unlock. The cards that you listed, use non-reference PCBs, therefore, will not unlock.

Just what he said it isn't the right one. I don't even know if they have them any more for sale or even if they make them. Good luck to you.
