that would result in more than 240MHz pixelclock.

He said his monitor can handle 117 Hz with dual-link DVI, so that's around 58.5 Hz with single-link DVI. The limit won't be exactly half, so he can probably push a little more. He did say he was getting occasional green line artifacts at 66 Hz, so he was already pushing the limits. He only did this for testing, not for continuous use.

AMD cards support up to 297 MHz pixel clock with HDMI, but these monitors were not designed to handle higher pixel clocks with a single-link connection.

What do you mean by out of range error? The overclockable X-Star doesn't have an OSD, so it can't display an error. It doesn't have a scaler either, so it shouldn't be able to display 1920x1080 @ 60 Hz.
