How much cards per rig do you use? Have problems with 8 cards, but with ethminer - ok.
The max I have is 7 RX Vega cards per rig. The power supply I use doesn't have enough SATA power connectors for 8 risers. I would have to disconnect the SSD in order to be able to connect the 8th riser. However, with 7 cards everything works great. I assume it would work as well with 8 cards if I had enough SATA power connectors.
my cards working only in big pci-e slots via risers.
