Re: unstable stratum; try 1.0.7 beta in 107 branch release folder.
Re: mine on card 2 --cuda-devices 1, or mine 24/7 using --cuda-gridsize 2048
wierd, cuda devices 1, is still using both cards, so that didnt work
also using the --cuda-gridsize 2048 in the file after 'ethminer -g', made the .bat no longer open. so that also didnt work
ARE YOU MINING WITH CUDA GPUS? --
Try running with "ethminer -U", as "-G" indicates openCL cards, or AMD graphics. --scryptr
Thanks a bunch, so I'm using Two GTX 980s on Windows 10, with the 347.52 driver
when I use -U, i get "cuda driver version is insufficient for cuda runtime version"
A LOT OF AMD USERS POSTING--
Sorry, no offense meant. My suggestion is upgrading to driver 352 or better. However, there is a whole ball of wax with Win 10 that I have avoided by sticking to Win 7 x64.
One thing, I had a hang-up with my last nVidia driver update (361.xx). I just re-installed and upgraded to v364.72, and a lot of problems with mining software just disappeared.
I am definitely not a final authority. A good driver install may be what you need. I don't know what version you need, the Win 10 VooDoo i simply avoided. CUDA ToolKit v7.5 comes with driver 352.xx.
Good luck mining... --scryptr
