Note
This tweak is intended for use with GeForce/Quadro cards and ForceWare 55.xx - 7x.xx 3D Stereo drivers. NVTweak is not fully compatible with Windows 98/Me or driver versions older than 55.xx. If you do happen to run this tweak with older software, you could get errors at startup! To enable full compatibility, you will need to disable the options that are causing issues with your current setup.
NVTweak allows you to operate a graphics card out of normal specifications by overclocking and/or modifying how the driver operates. You should always use the overclocking utility with extreme care! I will not be held responsible for any damage that may result from the improper use of this program.
