I am building a mining rig with eventually 6 gpus. I just got my 3rd card and tested it and all seems fine. i added it via a riser and turned it on. the system boots up fine and goes through its initialization, but i only get a black screen. so i disconnected it and rebooted. Back to normal. Then i tried different combinations of 2 gpus and it all works perfectly, until i add a 3rd card. Anyone else have an issue similar and what be the reason/solution, please?
