This version is not so easy to use because you have to adjust "-h" and "-dmem" values often, I will try to improve it soon.
1. "-dmem 1" requires twice more memory, make sure you have enough virtual memory. For example, if you have 6 GPUs 8GB, set virtual memory to 6*8=48GB.
2. Check how much memory miner allocates, it shows something like "(Memory used: 5128MB)", make sure you have this memory on your GPU.
3. You can see low hashrate if you use almost all memory on GPU, try to reduce "-h" value a bit.
