I have two video cards. My main card is a nvidia 650ti and my second is an AMD R9 280x. My monitor is connected to the nvidia and I use it for normal things. I want to start cgminer only on my second card - the AMD R9 280x. I tried with
cgminer -d1 but it says:
ADL found less devices than opencl! There is possibly more than one display attached to a GPU Use the gpu map feature to reliably map OpenCL to ADL WARNING: Number of OpenCL and ADL devices did not match! Hardware monitoring may NOT match up with devices!
I saw that there is this command:
--gpu-map <arg> - Map OpenCL to ADL device order manually, paired CSV (e.g. 1:0,2:1 maps OpenCL 1 to ADL 0, 2 to 1)
I have tried it but I don't know exactly what arguments to use and it does not work.
How can I use the command to start cgminer only for my second card?
