When you say very many times, is it more than 3?

I recently changed benchmarking system to try to run algorithm for 3 switches before disabling. (Setting stat to 0). If is running longer than that, it may be a bug. I can test and address for next release, but this would be first report.

However, if you set the argument -No_Algo sib,keccak it should skip them.

Your oc seems fine, at least for a gtx 10 series. If you want to try to mine them, then adjust the intensity as I noted below. If not, then us -No_Algo and turn them off.

Let me know about the bechmarking, if its not stopping after third time of building database, or any other issues you may have.
