I think the selected speed appears in the xorg log. I see.. this is what I get:
$ grep Clock /var/log/Xorg.0.log (II) RADEON(0): Default Engine Clock: 500000
^^^^^^^^^^
engine clock is 500 Mhz.
but I get the same reading without the ForceLowPowerMode option..
indeed, the clock of this card is 500 MHz:

so you're saying that without any explicit indication, the ForeLowPowerMode option will make it run at half the speed..
yes. that messges just prints the default clock. ForceLowPowerMode sets the clock to half of the default value.
It's doing it. How are you measuring temperature? GPU temperature support is not implemented yet in the open source driver. If it's a general case temperature, it may have more to do with the other stuff inside than the GPU.
there's a single ACPI temperature reading within the system, this is the only thing I can count on now. all else is subjective, like fan noise, subjective heat on the keyboard, etc.
the machine is irrationally hot, and I'm looking for ways to make it cooler. the CPU seems to be handled already, verified that in a number of ways. my next possible choice was the GPU as an obvious source of heat...
Really depends where the thermal chip is and how well it's calibrated. If it's right under the north bridge or something, it well always run hot. Alex -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
