Using rivatuner to increase voltage to GPU on NVIDIA GT2xx cards
 

The news has been spreading like wildfire, Rivatuner has always been able to increase/decrease voltages with GT200 cards and others, but it has been a secret thus far...not anymore. All of my information is based on the information provided by justageek95 in this thread here. All credit goes to him, I am just doing what I do best, explaining in an easy to understand and follow manner.
