i posted here a couple days ago about this same subject, its a ways down and I got some good responses on how to make it work and I appreciate them. but it wouldn't work for me so it must be card specific. I have a hercules 3Dprophet 2 pro. I tried installing the the 12.41's and then coppying a dll file from a previous driver set and it works, it actually runs fine and places the overclocking menu in the display properties. but, as soon as i try to overclock the card it goes nuts. the srcreen shows a wonderful set of psychedelic colors and wont stop. I give up and will go back to one of the aftermarket shareware overclocking programs. I just hate have an extra app running or auto loading.
