I realize that you are trying to help. It seems the issue is the classified board, which my not be wired the same, as it is different and they may not have taken into account something with the BIOS, the updates, or the control panel, as it is a different PCB. It doesn't seem that EVGA has a direct answer, which I would think they would be able to provide at some point. Like I said, I have two bridges I will try, and see if I can get them to work. If mine work, it may just be his. If not, it may be the difference in the PCB.
As far as the Individuals that keep asking "will it work with the 760?" read the article..
http://www.evga.com/articles/00766/ It is publicly posted on page 1 post 1 and says Titan, 780ti, 780, and some 770 models. If it happens to work with something else, that is great. If it doesn't, it should not be a surprise.
