Errors in the miner program, not in device manager
Bios configured
Above 4 G enabled
All slots set to Gen 1
4 PSU-s, linked in parallel, One PSU powering mobo and 3 cards, each other psu powering 3 cards. The configuration is correct as it works as a charm up to 7 cards, once I add 8-11 the Claymore miner starts to ask strange, haven't had much time to try with Nicehash maybe but I think would be the same.
