Sure enough, the damned clocks revert back to default after applying changes in ATITool. I don't remember that occuring in PowerStrip?[/quote]Originally posted by: tcsenter
These cards are locked against overclocking when using original Catalyst Driver versions 3.4 and up.
If your card's clock speeds revert to default after running a 3D application you need to download a modified driver from http://softmod.techpowerup.com
I got that same message and my clocks also reverted. I did as the message suggested and got the "patched" drivers and now my clocks stay put.
