had that issue also with some R9 280x vapor-x cards, latest claymore is really pushing the cards.

When you see errors, try setting :

-i 8  
-cclock 1080   
-mclock 1500  
-tt 75

The sols are almost the same, and the cards that had these issues look stable

Only had 2 cards from the 16 that had these issues.
