Can't believe no one has asked this:
What drivers are you using? Are you using the 14.1 or 14.2 beta drivers? If so, uninstall them, and go back to the 13.12 drivers. You lose ~100kh with the 14.1b drivers.
Make sure you're using the setx GPU_MAX_ALLOC_PERCENT 100 and setx GPU_USE_SYNC_OBJECTS 1 commands, and make sure the environment variables show the change IN CAPS. If the system env variables are lowercase, it won't work.

I'm using the 13.4 drivers.
Anyhow, here are my results from testing all night. The "best numbers."
And once again, they're all terrible.

Stock: 486 hash and 71 temp.
Stock/10% power boost: 500 hash and 77 temp.
1130/1500/No Power Boost: 486 hash and 72 temp.
1050/1500/10% power boost : 561 hash and 83 temp
1150/1250/10% power boost : 525 hash and 81 temp. Little bit of artifacting.
1150/1250/20% power boost = 510 hash and 82 temp. Little bit of artifacting.
I have to ramp this card up to it's limit and sky high temps and even THEN I still get nothing.
