ATI's CCC - Overdrive - Greayed out (no, not another "key" answer)

[koocha]

Hi all

Been playing with my new 4980 but the overdrive section has greyed itself out.

I was overclocking like a goodun. Got it to 920mhz core and 1020mhz memory and thought I'd try and go a bit higher. I clicked on the "test custom clocks" button and it failed. Now everything is greyed out!

Any ideas how I can re-enable it all? unticking the "enable overdrive" box and applying, then clicking it again and applying does nothing.

Re-installing CCC should work.
