Hello, I have bought a Radeon 3870 because I have read in several tests that the current AMD 38x0 cards use very little power if idle. And since AMD has started to help make OpenSource drivers for those cards a reality there was no show stopper anymore. So now I have the card but obviously POWERplay is not used in Linux (at the moment I hope) because the whole system is using 50W more compared to when running Windows. I tried all 3 drivers (fglrx, radeon and radeonhd) with no differences in this regard. Found some hints that POWERplay can be enabled via aticonfig but not on my hardware: planetzork ~ # aticonfig --lsp Error: POWERplay is not supported on your hardware. I am running the following card: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3870 (prog-if 00 [VGA controller]) Subsystem: Hightech Information System Ltd.

Are there any timeframes yet? Many thanks in advance! Best regards, Jogi -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
