quoting @eshbeata
i'm using the built release it worked with the old cuda not sure why
and it always [23:28:37][0x00007fffe30433c0] Speed [15 sec]: 0 I/s, 0 Sols/s
Any specific solution here?
- What is your graphics card?
- Which miner (nheqminer-cpu, gpu or old) are you using?
- Do you have CUDA toolkit installed?
- What is your CUDA driver version (System Preference)?
- Can you paste the output of the following commands (only the miner you'll be using is enough)
$ ./nheqminer-gpu -ci
$ ./nheqminer-old -b -cd 0 -cv 1
$ ./nheqminer-gpu -b -cd 0
I received
Speed [15 sec]: 1.13333 I/s, 1.73333 Sols/s
way less than my CPU. I know my GPU is not really god but should do better than that. (I will upgraded it soon, but in the mean time I wanto to use this one)
NVIDIA GeForce GT 750M 2048 MB
miner: OLD
Yes I do have CUDA installed
CUDA Version: 8.0.83

@Edig unfortunately currently best nheqminer GPU solvers supports Compute Capability > 5.0 (you may check the list here https://developer.nvidia.com/cuda-gpus) which means GeForce 9xx series minimum.
I added older Tromp GPU solver builds (nheqminer-old), although they work on older GPU's (and sometimes don't) the hashrate is not really good.
I will suggest giving an OpenCL miner a try (https://github.com/justvanbloom/silentarmy), @denics recommended this in one of the closed issues.
Hope that helps.
