Atom. You are a star, but I'm stuck

[atom]

there is more stuff to play around with. try adding these: -n 800 --outfile-watch 0 --gpu-watchdog 0 --hex-salt --hex-charset

also try with -d 1, -d 2 and -d 3. this way you can target a specific gpu. a single 6990 is running at ~ 1865M on stock clock. if you get these everything is fine, the 6970 should be around 1966M on stock clock.
