--- Comment #11 from t3st3r@mail.ru  2013-06-16 18:38:35 ---
For me this problem happens as following: 

My HD5770 card could clock up to 850MHZ - highest state, 600MHz in medium power
profile and 150MHz is low power profile.

However automatic management (dynpm) would only cycles 600 and 850MHz clocks
and never goes to 150MHz unless I explicitly force power profile to low. Should
I tell such power management is dumb? It is! 

You can be pretty sure that down-clocking 850MHz card to 600MHz does not makes
big difference. However down-clocking to 150MHz makes a really drastic
difference in power consumption and cooler noize. Should I admit current Radeon
dynpm implementation suxx?
