Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)
ETC stopped mining for me as well on SMOS, ETH works fine. RX580 8GB cards... heck will need to move to another miner as well 
I have already file an issue on Claymore's GitHub. I hope it will be an update soon. I can confirm that ETH is mining ok.
