Having issues I connected this morning and everything looked good until it crashed about 6 hours later having trouble getting it backup. Using XMR Stak on Hive OS 6 GPU Nivida Rig my settings are below. Don't see what I'm doing wrong. By the way never did get a payout so my guess my settings are wrong even though it was connected and seemed to be running fine.
