Hello all, I need help, I have both MB gaming 6 and gaming 7 on z170 chipset.

7 GPU works well but I need connect 8 via m2 . Have anyone this configuration?

I cant find optimal setting for this.

Ports can go bad on these board pretty easily I noticed, https://www.reddit.com/r/EtherMining/comments/6l286u/msi_z170a_gaming_m5_8_gpu_nightmares/
You aren't alone obviously. Best route is to take it slow, individually test all PCI-Risers and ports and see if you run into anything.
