BFGminer seems to be more informative as to what's going on. This is after a short time period but it keeps doing the same thing.
bfgminer --scrypt --thread-concurrency 10752 -g 2 -I 20 -w 256
I tested one of these cards on a different pc and I get the same issue. There must be something in my config or drivers. I just installed 13.4 ccc on the new pc I tested. They were running 11.11 previously.

I'm not familiar with BFGMINER settings, but looks more or less the same than cgminer conf.
If I get it right with the config from above EACH GPU will use 4 threads. Shouldn't it be "gpu-threads" : "2,2" for each GPU to use 2 threads?
What does algo: c mean?
you can also try to use only one thread, in this case you can double the thread-concurrency.

I've been messing with the settings all day, I forgot to switch that back. I normally just have 1 or 2. Don't think it needs to be 2,2
