As axn said, it is a work type of GPUto72. If a factor is found the LL-DC

In the meantime my new gc arrived.
Isn't there a compiled version of gpu-ecm available compiled for

Or simply a working version for a GTX 970, GTX 980 or GTX 980ti?

same result as ATH at my computer, with k=8 it works correct (peak 9345MB).
I think there is a problem of GMP (not gmp-ecm) allocating more than 16GB of RAM for a single thread.
