Hi, I did a fair bit of searching the forums here and couldn't find a solution. (Maybe I overlooked it) I have a Leadtek GeForce 8800GTS running ForceWare 196.21 wunder Windows 7 x64. Whenever I go into the overclocking tab of the system tweaks dialog and change the values for core and or memory the values revert to the standard as soon as I click OK. Also, after I click Apply it does not appear that the OC went into effect. (I do not see the frquency increase in the hardware monitoring) I did find that my driver version is not yet supported by RivaTuner, so I changed the value of ForceDriverVersion to the latest supported version that I could find documentented for RivaTuner. (I forget the version I used and I've since removed the setting.) That did not change the behavior. Thanks to all in advance for any and all help!
