Two additional questions:
- how to know which voltage controller does each card have?
- where to find information about offset vbios mod for each kind of voltage controller?
Thanks again
About first question in general i2c dump
For second thing it ain't that simple. As far as I'm concerned for some controllers it ain't possible. The good thing is 90% of GPUs are based on 2 controllers where adding offset works. If you want to work it out hit me a pm.
