  1. While attempting to convert my older Maxwell (2GB) rig from zcash to btg, i’m getting a segfault with miniZ:

      Hi,

      thank you for leaving feedback.

      I is a bit late here but could you try the following and report back? We’ll try to get you and answer asap.

      1. Run nvidia-smi.

      2. Could you run miniZ with each que GPU separately? Or, at least separately for the GTX 750 Ti, and GTX 960?

      ./miniZ --url robertcnelson.m4a77d@btg.suprnova.cc:8866 --cuda-devices 0

      then

      ./miniZ --url robertcnelson.m4a77d@btg.suprnova.cc:8866 --cuda-devices 2

      and report if you get the same error?

      Although nvidia-ml doesn’t seem to be your main problem, it still needs to be solved.

      Thank you. Cheers.
