Default Re: FX 5200 DVI: No valid modes for "1680x1050"; removing.

If the mode is failing to validate due to the pixelclock being too high, then your only safe option is to attempt to generate a custom modeline (with cvt as others suggested).

You could set the NoMaxPClkCheck parameter for the ModeValidation option, however since your delta is 11Mhz, I can't see how that would ever work properly.
