No, unfortunately anything higher than 85Hz did not work for me. The screen remained black in each case. I think the cable meets the DP 1.1 specifications with 10.8Gbps. This one, on the other hand, worked: Lindy DP-DP M-M (7.50m, Midrange)
Unfortunately, the cable only supports 60hz at 4k.
According to the manufacturer, 4k/60hz is only supported up to 3 metres. I am not currently aware of any cable that transmits 4k/60hz over 20 metres, so you will probably need a repeater for such a length.
