Hi Ruochun,
thank you again now everything is working fine! 
However, I have another question related to the nvidia driver. For now, I 
have the 560 version and I have noticed a power cap on my GPU of 35W 
against the 110W limit specified by the manufacturer. Looking in some 
forums I understood that the problem may be related to the driver itself, 
therefore I want to update it. Do you know if this will cause any problem 
to DEME?

Thank you again.

Gianni
