Hi,
I am running several 7950 around 580mH/s for a while now. During the night, one card hanged out so I restarted the rig in the morning. Now, I am getting only around 250mH/s on that card to matter what I do. Any ideas what is wrong?

Thanks

Solved. Just rollbacked the drivers and played with the Catalyst installations.

For completeness:
Had a similar thing. Its caused by all the clocks resetting to the lowest possible for some reason after a driver crash. So although it was hashing fine, it was likely hashing at 300MHz core.

Fixed by manually setting the clocks back or reinstalling drivers as you found.
