my results.. for 680

Can you run the miner same minits that we can see the hashrate. My driver under windows also crash, thats windows like shutdown^^

my results for 560ti

Autotuning is on because no gridsize is given
To big grid size fixed!!

:180[CUDA] Error: unknown error

app crashes..

Plese use -aggression=6 as parameter, the gpu is to slow and braek the kernel run limit.
