Just like the pencil mod for the 9800XT

"Locate the resistor as shown above and start to pencil it slowly, a few strokes should be sufficient to increase the VGPU from 1.31v to 1.4v. I have tried higher voltages but i have found that any voltage higher than 1.45V seems to be a little too much and the card will start artifacting during benching. Therefore i have left the VGPU at 1.4v which is pretty sufficient for air cooling."
