NVIDIA 9600 GT Voltmodding Article
 

NVIDIA's Geforce 9600 GT is quite an exceptional midrange card that offers excellent overclocking potential. Since the cards run at a relatively low voltage there is some extra overclocking waiting to be unleashed by raising the card's voltages. The GPU voltage mod we present in this article uses a new method which will not be affected by the card's overvoltage protection. Also we describe an easy to do modification to increase the memory voltage.
