I've been mining Judge coin from the start just to show my support. 
I have a question though with my mining rig if someone here with good knowledge may be able to help me. 
Just recently one of my cards will suddenly become dead. 
After I have rebooted the rig it will show all cards hashing normally, then after a certain length of time one particular card always becomes dead. 
Any help on this matter would be greatly appreciated.  
i had the same issue 2 times with asus 280x cards.
with first card i was able to resolve the problem with a firmware upgrade.
i had to replace the second card (exchange under warranty). 
i isolated both cards, used them within a normal desktop system and did some tests with 3d games. first card was ok -> firmware upgrade -> mining ok
the second card was always crashing after 10 -20 minutes while running 3d games on the pc, so it was clear there must by a damage.
i had some problems with dead cards while mining scrypt-n coins months ago. this was cuz i had not enough ram.
not sure if this can be a problem with x algos. the strange thing was: 
it was working for a month or 2, after that i had to upgrade to 8gb ram (3 gpu's/per worker) 
with 4 gb ram 1 card always died after a certain time.
hope this helps! 
forget my bad english and good luck
