The NiceHash Equihash miner fails to benchmark on GPUs when the "t" flag is set to 0. Without the "t" flag set, the benchmark is performed on both the CPU and GPU.

The results reported are likely sums of the units' hash rates.

With the number of CPU threads set to 0, however, the benchmark does not run properly.

Now we don't get correct results for the GPU's hash rate. So of course it is necessary to set the "t" flag to 0, but the miner does not react to this correctly. This could be an issue with nheqminer.cs (https://github.com/nicehash/NiceHashMiner/blob/master/NiceHashMiner/Miners/nheqminer.cs#L66$L71) or the miner itself.

I have the same issue.

NiceHash Miner handles this correctly. You can check your logs that generate benchmark input. If you are referring this as an issue with nheqminer open an issue there. But nheqminer is intended to run on CPU by default.

0.3a version was compiled only for compute capability 5.2 , your card is older, you need compile cuda_tromp.dll for your card or use older (slower) from version 0.2a .... Or you can try dll compiled by me http://chronx.pl/cuda/cuda_tromp_0.3a.zip (cc2.x-cc6.2)... if not work try decrease number of blocks (-cb option) or threads (-ct option)

@chronosek Thank you. it works.
