Here is a full modding guide for the Ati HD4870X2 gfx card.
you need a screwdriver and a sharp knife and a good solder iron and some small wires
And 2x50 Ohm and 1x50K Ohm Multiturn Vrs
And a lot of paticence.
The first thing we have to start with is to dismantle the card.
The card it self.
The back of the card.
And now to unscrew all the screws.
And then we can take the back cover of the card, be carefull not to harm the mempads
as you are gonna use them again.
The rest you can se here..
