Try "launch-config" : "28x128" as your launch parameter
Best of luck!
Thanks. I just tried but still the smae fatal warning. ccminer works fine on other algos but i cant get it to work on this one. I'm downloading latest nvidia drivers and see if any differense.
I had that error at first, but after a bit of tuning its working flawlessly. my launch parameter is as follows
"launch-config" : "66x7"
Maybe you could try this one, or do what I had done and start from low-ish numbers and work your way up EG: "8x16" & so fourth
