I did the flash using my 7800 GTX go, I used the 780GTXUN.ROM file, and it said the flash was successful. However, my clock speeds still do not stick! When I use ATItools, Rivatuner, or the Nvidia drivers themselves, if I make a change, then exit, then reload them, they are back to the default clock settings. I'm running an XPS gen 2... have I missed something?!
Also, I'm using windows XP, with geforce tony's 91.47s (which I know are older, but they are the only drivers that work properly for me).
