I have 1 card that is half full of x's in low clock mode (x x x x x x x x o o o o o o o o). If I switch to high clock mode and restart, it goes to all o's. But when I switch back to low and restart, the x's return.

Anyone know what's going on or how to fix it?

Also, is it normal to always get these "WARNING proxy getwork_listener._on_submit" messages? I seem to be getting a lot of work accepted (27 gh/s on slush's pool), but I'm getting lots of WARNING spam.
