I finally got this running on my ASUS motherboards apperantly only one Nvidia drivers works stable with 19GPU mining board.

T-Rex algorithm performances for 1080Ti:
lyra2z 65TDP +151 core -400 mem = 4288 Kh/s 59'C
lyra2z 65TDP +151 core -502 mem = 4413 Kh/s 58'C
lyra2z 70TDP +151 core -400 mem = crashing
lyra2z 70TDP +151 core -502 mem = 4490 Kh/s 63'C
So far for lyra2z best available miner!
