nVidia is apparently unhappy with people overvolting their video cards for higher performance. The guys over at Guru3d have the full scoop , with lots of comments from EVGA_JacobF over at the EVGA Forums, but the jest is the EVBot is gone:
It has come to our attention that NVIDIA is making sure that there will be no voltage control for their GK100 line up. In a forum post on EVGA forums, EVGA employee Jacob (EVGA_JacobF), responded to question about why a new GTX 680 Classified shipped without an EVBot port.
The initial assumption by members was that this was just a manufacturing defect that accidentally passed QA. However, here’s Jacob’s response to the initial question.
“Unfortunately newer 680 Classified cards will not come with the EVBot feature. If any questions or concerns please contact us directly so we can offer a solution.”
Crazy stuff. I imagine all other manufacturers will be following suit soon (Hotwire from ASUS, etc)
