Custom Resolution Utility (CRU)

Is there anything I can do to get 80hz refresh rate?

80 Hz at what resolution? What type of port? DVI? HDMI? DisplayPort?

Single-link DVI is limited to 165 MHz pixel clock without driver modifications, and I don't have a patcher for Intel.

HDMI often has the same limit unless the EDID includes HDMI support with a higher limit. With CRU, importing the hdmi.dat file would include the higher limit.

The pixel clock is the total number of pixels per second (horizontal total * vertical total * refresh rate), so reducing the totals will reduce the pixel clock. You might be able to get 75 Hz working if you reduce the totals. CRU has an "LCD reduced" timing option for this. Intel's advanced custom timing options don't seem very user-friendly, but you can use CRU to calculate the values and copy them over.

You could also try using CRU, but I don't know if it will work with your setup. Intel's driver didn't support EDID overrides in the past, but I don't know if that has changed with newer drivers. I don't have any Intel systems to check myself.
