This forum is littered with casualties (from this "bug fix"). Join the club.

I just hope nVidia is going to remove this "feature" soon.

Oh, ok, and there is no mean to force this badly calculated max dvi clock ?,
like the edid values ?

Why does the validation routine for the video cards is not the same as in the windows drivers, where it just nicely works since ever ?
