Thanks for pointing that out, I thought I already applied that option by specifying "NoDFPNativeResolutionCheck" with a new line of Modevalidation directive. However, it was not in effect because the correct syntax is to put all modifiers into one line, separated by commas.

After forcing all my will on the monitor, I got a garbled screen with obvious line sync problems. Seems to me as raising the refresh rate above 60Hz in 1680x1050 is beyond the display capabilities in terms of pixel clock, no matter how much I tighten the mode timings (that is, narrowing the space offscreen for synchronization).
It was 75Hz though.
