4890 Voltage
So i downloaded GPUTool to increase the voltage. My first question is what is the max voltage on a 4890? 1.4?
__________________Second question, on the gpu tool i have 2 voltage options. VDDC and another one which only shows question marks. What is that?

i think 1.45v is the max you can get out of the voltera on these cards, i may be wrong. something to keep an eye on though is your mosfet temps.

1.4v is the absolute max you should run with air cooling, anything over that and you really should be looking at watercooling the card.
