Very informative post

What OS, drivers, GPUs do you use? Do other CUDA miners (for example
https://bitcointalk.org/index.php?topic=1707546.0) work on your system ?
Appreciate the quick reply!
Windows 10 x64, Nvidia 1080 x2, drivers 397.31, EWBF's Zcash CUDA miner. 0.3.4b works on my system.
I used the default config as it seems proper for Nvidia, and tried disabling all but first 2 devices in the config but same results. Anything for me to try?
