There is some kind of black magic in this miner... I have 2 rigs. Same hardware and some mixed pascal gpus. Same system win7 x64, with same updates and same nvidia drivers version.
1st rig sgminer -n shows all gpus and mines without any problem.

2nd rig it shows

and offcourse it doesn't work.
So there is a catch with igpu...
Once again-same mobo, same bios, same cpu, same system, same drivers, no displays connected. All other miners works on both systems.
I'm mining other coins with those 2 rigs and I would like the 2nd to work just for testing 1080 and 1080ti hashrates aswell. Any idea?
