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

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.

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