Here is the workaround:
Open CCC and switch to ATI Overdrive
Unlock and enable Overdrive
Go to Options/Profiles/Profile Manager and create a new profile called, let's say, STABLE.
Save the new profile. But DO NOT ACTIVATE the profile.
Now go to C:\Users\{YourUserName}\AppData\Local\ATI\ACE\Prof iles folder ( I assume C: is your system drive )
Note: You should have " show hidden files " turned on to see the folder.
Open the .xml file named STABLE with notepad.
Change the values of the idle Core clock and Memory clock speeds below
Feature name="CoreClockTarget_0"
Property name="Want_0" value="40000" note: previous value should be "15700"
Feature name="MemoryClockTarget_0"
Property name="Want_0" value="90000" note: previous value should be "30000"
Save the file and close it.
Go back to CCC and activate the profile. This will make the card idle at 400 MHz core clock and 900 MHz memory clock.
The speed change is immediate. You can see the speeds onder CCC Overdrive section.
Please note this change increases graphic card temperature by 6 to 7 degrees C at idle.
Those having issues under load,such as gaming, should not need this workaround.
Hope above helps.
