Hi,

I'm using the xf86-video-ati drivers and everything works just fine. Even dynamic power management with dynpm works. Although power management works (profile: low), the fanspeed is set to about 40-50%, which is pretty loud.

Is there any way to control fan speed (temp sensors work) with lm_sensors? I couldn't find anything about this issue here or elsewhere besides some old articles [1] and the Radeon & LM_Sensor posts on gentoo-wiki.com.

thanks,
Daniel

Are you using a second or external monitor?
This post is from August last year and I am still waiting for my repaired card (fried) :(

could be the memory clock?

I'm using it with an (one) external monitor (PC, not notebook) with a Radeon HD 4850 (using the RV770 firmware).

that there are only two different power states (engine: 750000, memory: 900000) and (engine: 500000, memory: 900000).

With this kernel patch [1] you can set the clocks manually:

Code:

echo profile > /sys/class/drm/card0/device/power_method
echo auto > /sys/class/drm/card0/device/power_profile
echo 300 > /sys/class/drm/card0/device/engine
echo 300 > /sys/class/drm/card0/device/memory
echo low > /sys/class/drm/card0/device/power_profil


result:

Code:

~ $ cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 750000 kHz
current engine clock: 300000 kHz
default memory clock: 900000 kHz
current memory clock: 300000 kHz
voltage: 1263 mV
PCIE lanes: 16


It's just a workaround, but: silence! finally.
