I have two MSI 5700XTs and an Asus ROG. All three are detected by HiveOS but will not start to mine. I think all the connections are good as the risers, ports, etc all work if I swap out for 3070’s. I have not attempted changing bios, etc.
I did get one to mine once…at 750kh. So a little more than 1% of what I expected. Then, upon reboot, no mining at all.
