Catalyst 12.1 crossfire problem

[HankScorpio]

Hello

I just got a prompt this morning to update to catalyst 12.1 and after noticing my PC being very quiet (as I fold@home on two 5770s) I looked into AMD overdrive and only 1 gpu is displayed. I went to AMD vision engine control thingy to enable crossfire and everytime I click enable it freezes for a few seconds then reverts to disabled.

Any idea how to fix this or how I can revert to the previous catalyst?

Thanks

how I can revert to the previous catalyst?

System Restore to before you installed the new drivers.

Cheers man, it worked.

You're welcome.

You might have more luck downloading the new drivers direct from AMD and installing them yourself rather than using automatic updates.

I'll leave it with you if you want to try that.

And Uninstall the old ones first.
