================================================================
when i try 65 bits, i get segmention error. But if i drop the bits to 60 it works fine. I am using Geforce GTX 2070 with ccap 75. Any thoughts please?

Try replacing
#define NB_TRHEAD_PER_GROUP 128
at
#define NB_TRHEAD_PER_GROUP 64

you should go back in earlier post to you, where i said you need to correct define, block, thread and process, and you will get 10x faster speed

hope you soon you will able to assign this in user level with switches -b -t -p , as per bitcracked assign for manage load of full GPU power
