Topic: gpu mining with sapphire 7950 dual x shutdown problem (Read 1650 times)

That is really weird, I think its your setting problem.

Off hand I would say try a different driver version.  Also is your cooling sufficient?  You should be able to go higher intensity than 13 on scrypt, scrypt-n, and x11 at least from what I have seen but if your ambient temps are already summertime high then the card will get hot fast.  Although usually an overheat causes a blue screen from what I have seen.  But something to pay attention to anyway.

BTW I don't have that specific card but I do have a few different kinds of AMD cards in my farm so I am talking from my experience with those.

i am facing shutdown problem sapphire 7950 dual x
i am using this script in cgminer

cgminer --scrypt -o stratum+tcp://pool.com:3322 -u user.worker -p x --intensity 13
