The Vcore mod is done using a 50kohm variable resistor set to 0 ohm. You increase the vcore by increasing the resistance. As you can see you connect the resistor pins to the black and white cable. There should be a 0 resistor there, you have to unsolder it
The stock voltage is:
1.1V in 2d
1.35V on rev. M cards in 3d
1.45V on rev. H cards in 3d
The Vddr mod is something like a Vdd mod on a Radeon 8500/9xxx
I used a 50kohm Variable resistor set to 50k, the second pin is connected to ground. You increase the voltage by decreasing resistance. The stock voltage is:
2.5 to 2.55V on rev. H cards
2.6 to 2.65V on rev. M cards
