Errore di segmentazione (core dump creato)

This is mainly related to these possible issues:

1. You're overclocking too much
2. If not overclocking you have a problem in data transferring from pc to gpu (is your GPU on board or is it connected through a raiser ?)
3. Segmentation fault means the program cannot access a specific memory address: either you have faulty ram on your GPU or, may happen, your PC has a faulty ram.

2,100,232,192 bytes GPU Memory is not enough.

[AndreaLanfranchi]

Whoops ... didn't see you had only 2G of ram on your GPU.
With that GPU RAM you can only mine UBIQ with ethminer.

I think this issue can be closed.
