Are you, by any chance, trying to run with an overclocked GPU? In my experience, there is little gain, and risk of damage. I don't do it.

Also the help file in the zip file of almost any posted Windows build; rerun gpuowl-win -h on your own hardware to get the correct device number to gpu model output for your hardware.

What does g++ --version say?

You might have to hardwire your compiler name and version in gpuOwl's makefile.
