I'm not able to mine raven with the default settings at auto nor others

wildrig.exe --print-full --algo kawpow --url stratum+tcp://rvn.woolypooly.com:55555 --worker test --user RJjr1sMM2uVsiBpUN86vgbs3JnkPzwfWFD --pass x --opencl-threads auto --opencl-launch auto

I've tried 1 and 2 threads, lowered intensity from 23 to 18.  I just get crashes.  Any ideas?
