Hi,
I tried "OhGodAnETHlargementPill-r2" with my 6 x 1080ti, but I only went from 35Mh/s to 40Mh/s. Anyone else in my case ?
Mystery solved !
It seems I had a very old version of SimpleMining on this rig since it was running for a very long time. So I flashed a newer version and now I go from 35MH/s to 51Mh/s. Excellent !
