Maybe you heard but windows 10 now supports 8+ same brand gpus with the fall update. But the problem is ccminer 2.2 does not support 10+ gpus, so I should had to replace ccminer with the latest version (2.2.2). The same problem is available for the ccminer-alexis and for the other ccminer forks (nanashi, sp-mod etc.). I suggest splitting the miner threads by at least two (10+3, 9+4 etc.) for 10+ users at least for now for the alexis and other forks. And you should urgently update the tpruvot version to 2.2.2 for the 10+ users. On the other hand there comes 19gpu supported version with asus b250 boards. The same problem may arise with that, too.
Thanks
