He actually describes it in the thread, a little farther down: "No, no schematic, what I did was look for resistors that looked like they had an alternative position, have a look at the photos and you will see what I mean. Any that I suspected of being a strap I used a meter to check if the resistor was connected to ground of 3.3V directly, and looked where the general traces were going in the area. If they went towards the GPU and connected to one of the rails it was a pretty good bet that it was a hard strap." http://www.eevblog.com/forum/projects/hacking-nvidia-cards-into-their-professional-counterparts/msg203225/?PHPSESSID=f88387c520550af1e0508d8687b41928#msg203225 http://www.eevblog.com/forum/projects/hacking-nvidia-cards-i...
