DiabloMiner - Both GPU's stuck at 2D Clocks (Windows x64)

[Real]

Both of my 7970's will not run at full clock speeds using DiabloMiner, as such will only achieve ~250 to 260 mhash/s.  Using GUIMiner / cgminer with -k diablo, this is not an issue.  Any ideas?

low hashrate can be efect of many things, check if You are realy stuck in 2d clock by downloading gpu-z.
if it is low clock:
- check if you dont have a video paused in browser and close the tab
- apply newest beta drivers , 12.10 are f...ed up with 2d/3d clock change
 -  downgrade drivers to 12.8
