cuda core count
I have asus ASUS N76 R701VM-V2G-T5065V and i use Mathematica on it. On specification is written it has 384 cuda cores, but when i start cuda in mathematica it said only 64 cores are visible?!
I dont use gt650m as graphic card (there is some other in notebook, so that one is used as graphic card and i need gt650m as GPU only).
So i dont get it, whats the problem?
Can anyone plz help me!

The software probably is too old to know that one SM(X) now has 192 cores and still assumes the compute capability 2.0 value of 32 SM per SM. Nothing to worry about, it will still use all cores (although it will not be optimized to take full advantage of new capabilities like register shuffling).

Always check return codes of CUDA calls for errors. Do not use __syncthreads() in conditional code unless the condition is guaranteed to evaluate identically for all threads of each block. Run your program under cuda-memcheck to detect stray memory accesses. If your kernel dies for larger problem sizes, it might exceed the runtime limit and trigger the watchdog timer.
