from the article.. pure retard..
The ASUS MARS II supports extremely limited overvolting. We could only raise the GPU voltage from 1.050 V to 1.075 V. This enabled overclocking to go up by around 20 MHz.
I would have loved to see how this card does with more voltage, especially considering that the beefed up VRM eliminates the chances of the card exploding. Unfortunately without more info on the voltage controller I can't write my own overvolting application that bypasses NVIDIA's limits.
