Again I can not turn off gpu0 !! with the help of the graphic interface - no. Using config.json also does not. It works with 0 or 0,1 or 0,1,2 or 0,1,2,3 .... 0 does not turn off !! NO !!!!!!!!!! "SelGPUCC": "1,2,3,4,5,6", - does not work !!! gpu 0 always works !!!!!

Are all the GPU in use still?
Sometimes 0 is not the one you think and you might need to disable 2 or 3 instead.

config.json :
"SelGPUCC": "1",
Miner :

Thanks for helping!
Could you try to download from master?
There is now a ManualConfig parameter in Config. If set to true, NPlusMiner GUI will not overwrite config.json.
Note that all config changes must then be done manually in the file.
This should fix your issue. Could you test and report?
