The default configuration that the miner suggests crashes the application (32x15). The best value is 20x15 and it crashes 26x15 and up. Not sure if the mobile have another requirements beside the 85% memory usage and the 950 threads.

I assume you're on windows, because I've had similar issues (32x15 works fine on linux). Try 8x30, it's the closest I've gotten.

The problem with CUDA is that it used in special cases extra memory for a kernel. It is not possible for the miner to calculate the extra amount, therefore the suggested config sometimes crash on low end cards. I will check if I can improve the suggested config.

Please reduce the number of threads up to a working configuration.

@esfomeado Try 24x15, I found that to be the best configuration for my set-up. Note also that the 960M can come in different memory configurations - 2GB and 4GB, and the actual layout of memory will be different depending on the vendor.

Hi, I'm new at mining and I have tested Minergate. It had a bad reputation, so I switched to xmr-stak on xmrpool.eu. I have a 960m 2GB and the default hashrate is poor : ~40-70 H/S It was ~250 H/S with Minergate. I found this thread : help_cant_mine_with_nvidia_gpu So values crash (maybe for the 4GB version) but I can reach ~110 H/S with this setting : 

  { "index" : 0,
    "threads" : 8, "blocks" : 30,
    "bfactor" : 6, "bsleep" :  25,
    "affine_to_cpu" : 0, "sync_mode" : 3,
  }

Their is a tips to reach the Minergate performance ?
