ive heard about using this to unlock certain things on motherboards and so on so my question is do u just put it there then take it away or do u have to find some way to hold it there?
well, the pencil mod is to connect the L12 and L3 bridges on the barton cores. Or, you can find the pins on the underside and connect those either of those work. It is used to overclock and open up the higher multipliers on the bartons. They dont work for the A64's because of the IHS they put on there. But you can always pry it off for a better heat conduction.
