7900GT over voltage protection?

[t024484]

I'm afraid it won't be much easier...

BUT: If Pin 32 and pin 22 is *already* '0', why not just connect
Only pin 32 to pin 30 and 31 to get 1,350V or
Only pin 22 to pin 21 to get 1,4V or
pin 32 to pin 30 and 31 AND pin 22 to pin 21 to get 1,55V

Would that work?

Yes, this will work. Without changing the Resistor, you will have 1.55Volt.
Do not worry about burning pull up resistors as somebody suggested, these pull up resistors are very large in value.
To be more specific, the internal pull up resistors are in fact internal current sources, supplying 40UA ( 40exp-6 Amp) of current wen the input is connected to ground.
