Talk:How to make use of Graphics Chips Power Management features
Experimentally, it seems that rovclock determines the maximum frequency, and "DynamicClocks" tells the chip to a lower frequency when possible. They are thus complementary. --Thinker 18:59, 27 Oct 2005 (CEST)
show current power state with fglrx?
Switching power states using aticonfig
seems to work fine. Seems, because I can't really see in which state the ATI chip is currently in. Or can I?

You can (destructively) check whether it's in a specific state by trying to switch to that state. If it's alredy there, it will give an error. If not, it will switch and (on my machine) cause a brief screen blink. Indeed, brilliant engineering.
