I have a 9800gt made by hp that constantly runs at full throttle and never down clocks the card when idle. The card idles around 60C. I would like to add some power management options to the bios so the card down clocks itself at idle. I did some testing with nvidia control panel and found the perfect setting for idle for the shader, memory and core. I then extracted the bios from my card with GPU-z and edited the bios with NiBiTor. I then used a usb stick and flashed the edited bios onto my video card(with nvflash and dos). The only problem is my card still does not under clock itself on idle. Does anyone know what I am doing wrong? Thanks!
