I downloaded the above recommended utility to attempt to overclock my GTX 260 but the software does not appear to be working. I do not have all the items you have listed in the control panel. What I do have listed in the advanced portion of the control panel is: Performance/ Device settings, View system information, Profile policies. Nothing more is listed not even 3D settings, Display, System stability, or Video & Television. Please help, Bob
What driver did you install for your GTX 260? Did you download and install the latest driver from NVIDIA?
