7900GT over voltage protection?

[***Deimos***]

So this is correct right (just asking to be sure)? to get 1.5V

yup.

Belarnion, that looks right.
However, personally, I would not do it that way. The pull up resistor for ~+5V , will now be between 5V and ground, and perhaps too much current for it.. ie burn it out. Perhaps we should wait for the experts to confirm.

Majestik.. yes you can install dip switch. But, to make full use of it, you would need to solder so many wires, one for each of the vid pins. It would be really cool though. You could just toggle whatever setting you want. If I had a 7900GT and the necessary tools (I dont even have proper soldering equipment for such miniscule stuff), I would definetly install a dip switch.
