the 780 is this compute 30 or 35 ?
My 780ti works well on it.
I think too, it is a problem with the gpu not working properly on your card, if it always return, it means it doesn't work properly.
however, the 750ti shouldn't have any problem.
Any of your cards attached to a monitor ?
For info it was compiled with vs2013
and boost 1_56 (the others dependencies being those of ccminers, except for pthread which isn't needed. )
also make sure you have the latest drivers and compiled with cuda 6.5
The miner still doesn't works here.
I'm also using VS2013. I've downloaded and installed the latest driver and CUDA Toolkit today. I'm on Windows 8.1 if that makes any difference. The Nvidia card is the only card in the system and it's attached to the main monitor.
I am also on 8.1, try to go sk1024.cu and replace const int throughput = 512*8 * 512 * 4; by const int throughput = 512*8 * 512 * 2;
