And that's the rub. You may find that in order to fix something else ATI has changed something that now F's up your OCs. This happened before with another update where alot of people who were OC'ing suddenly found that their temps were going wacky, and it was because they had changed how the cards handled certain functions. I think it was 3.10 IIRC.
Anywhoo, I haven't heard/read anything pervasive yet, but really it's likely going to be an issue of trouble-shooting. And perhaps your best solution will be to stick with an older set of drivers to get the OC boost/benifit. ATI likely will just give the industry standard... we don't support people running their cards outside of the spec, with the exception of Overdrive... yada, yada, yada.
The first step is to always see what happens at stock, then find out where the issues are coming from. OC back up and you may find the stable levels have changed.
And until you can fidle and rule things out it's hard to trouble shoot from a distance.
