screenshot URL doesn't work.

maybe you are using the wrong version of the miner for the coin. Are you using Nvidia or AMD?

what coin are you trying to mine?

I have just the same problem with my PowerColor HD6790. It works only with GUI Minergate program, but very slowly.
Any console miner does the same, they say about "incorrect data received from gpu" with Claymore's Zcash AMD GPU miner or "banned for invalid shares" with Claymore CryptoNote GPU Miner.
I have three computers, the other two are running HD7770 and R7, and there are no problems with them at all, using the same version of Claymore CryptoNote GPU Miner, with same config.
Now I'll try to install new drivers from amd site.
