I have one of these http://www.gigabyte.com.tw/Products/VGA/Products_Overview.aspx?ProductID=2720 lying around. These cards have a some sort of fintek-brand voltage regulator chip which allows gigabyte's "GamerHUD" software to change the GPU voltage on the fly. However, I'm really not a fan of gigabyte's software, and would prefer to use rivatuner to manage voltages as well as clocks. I've been trying to mess around with RT's "graphics subsystem report" to see if I could capture the relevant registers, but I haven't had any luck -- changing the voltage doesn't change any values in the report. However, given this thread http://ocxtreme.org/forumenus/showthread.php?t=4427 it seems that rivatuner can see a lot more from the command line than the GUI lets on. Any ideas/help on the relevant commands to allow me to look at what registers get changed when the GamerHUD software changes the voltages? Has anyone attempted something similar with this card/GamerHUD?
