I'm done trying to mine this shit coin with this shit Claymore AMD miner.... Going back to mining Ethereum.... At least that miner will run reliably without hanging up every god time I leave the house for more than a few hours!
Get nVidia cards
Or get better HW/OS... running Claymore ZCash 24/7 on Windows without any problems. Or you can try Optiminer, but I had stability issues with it.
