elmor Posted October 28, 2013 Share Posted October 28, 2013 The eVc device uses the 2-wire/I2C/SMBus interface to communicate with the VRM controllers on the graphics card. This interface works by using two signals (Data/SDA and Clock/SCL) plus a ground reference (Ground/GND), in total three connections. These points can be found by checking the datasheet of the VRM controller (the ground reference can be any ground point on the graphics card). If you have a card you suspect can work with this device, feel free to post in this thread to get help adding support for it.
