nVidia BIOS Modifier has been updated to version v3.0 ! This tool must be used by ADVANCED users ONLY! This tool works correctly with BIOSes of 6x00 / 7x00 series cards ONLY (including QUADRO series, built on NV4x and higher) !!! BIOSes of 5x00 and older aren?t supported. Added to build 3.2:

Extended / corrected list of supported cards. The limits of delta (for NV47) were changed. Now delta parameter can be both positive (?+?) and negative values (?-?).
