GPU Miner MacPro Error-30

danielbo

Hi Panda (and others of course!!)!

I started using the GPU-Miner on my MacPro (6,1 , 12Core, 64 GB, OS 10.12.6) but i only receive the following error-log.
CPU-Miner is running well.
Beside of the internal Dual D700s i use a NVIDIA TITAN Xp (12GB, latest NVIDA-Drivers) in an external TB-Enclosure.
Would be nice to get all 3 GPUs running to crunch some numbers...

Thanks for your help and happy mining !!
Daniel

i should mention, that when the NVIDIA GPU is disconnected i still receive Error-30 BUT the miner starts working as expected!

I wouldn't be surprised if there were a problem mining on nvidia and AMD cards in the same instance. You could try running one in the GPU window and one in the ASIC window with manual flags for the GPU. However it's impossible to GPU mine Bitcoin these days, the difficulty is just too high so I'd really suggest looking in to other algorithms and currencies.

thanks for the reply!
is there a wiki/manual on how to manual setup GPUs in bfgminer /ASIC-miner ? or could you give me tipp how to do so? thanks in advance, daniel

There's a bunch of specific GPU mining information here:
https://github.com/luke-jr/bfgminer/blob/bfgminer/README.GPU

It advises using
-S opencl:auto
to enable GPU mining when combined with ASICs so this is just a guess but I think maybe you'd use
-S opencl:OCL0 or -S opencl:0
to enable only on the first GPU
