So I received mine today & finished assembling them. When powered on I can get it to identify all 4 boards. However only 1 or 2 will mine. The board that mines isn't always #1. It seems to be random (after mining for approx 10 minutes Asics on the good board start to go bad). The dip switches are done correctly. How they are powered isn't the issue. Originally was using a 1200w psu. Added another 850 with each board having 2 pci-e. Didn't make a difference. Have also used different controllers.
Any ideas or something that I am missing? Have tried 3 of 10 with same results so far
Spent another 2 hours on them trying every different configuration, psu, controller, connector option I could think of and I was unable to get any better results. Max I got 1 to mine at was 250GH with 2 boards mining and 13 of their asics showing bad.
