I'm running 3 7950 cards with GUIMiner and one of my cgminers end up crashing after a certain period of time, but the other 2 cards seem to keep on hashing. Temps are 69 and under 70 with all cards. Usually remote in and see that cgminer.exe has crashed and had an error or whatnot, but when I check my workers online 2/3 of the cards are still running and its just one that isn't due to the crash. Anyone have any ideas what the problem may be? Hashes fine until the program crash happens so it seems to be a software issue.
