    With the HD5870 dynpm doesn't work, it keeps using the high profile
    Fortunately the low profile does work VERY well, it's 20C colder
    Thanks for reporting, dynpm is hard flawed according to Michael tests as well.
    Perhaps open a bug on freedesktop?

      Where can I buy it? Is there anyone else in Europe interest to buy it?
      Why not use a generic energy measurement device for eurosocket? Costs around 9, fairly efficient.

        On opensource drivers power managment dont work at all on my Sapphire HD 2600 XT. I tried every state - nothing happens, even dynpm doesnt works Tested on Ubuntu 11.04 amd64 and gentoo amd64-2.6.38. /sys/kernel/debug/dri/0/radeon_pm_info always same:

        Code:
        default engine clock: 800000 kHz
        current engine clock: 796500 kHz
        default memory clock: 700000 kHz
        current memory clock: 693000 kHz
        voltage: 1200 mV
        PCIE lanes: 16
        Code:
        sensors:
        
        radeon-pci-0200
        Adapter: PCI adapter
        temp1:       +82.0 C
        On fglrx everything works.

          Yes, I will. Unfortunately I have a long week ahead, hopefully I will be able to report it next week end.

            9? I didn't see any so cheap, anyway I can even keep using the ups, the watts up pro was more interesting because you can connect it to the pc and it has linux drivers.

              Yes, maybe. But I just plug that 9 thing in PC socket and it can show wattage, peak wattage, power efficiency etc. And to test if its showing right, plug 40w light bulb in it or something similar.. I mean, of course maybe wattsup shows more precisely and can report back the consumption to the machine, to use it in scripts etc. But for random drain check the basic 9 thing is more than enough. Is in every supermarket.

                Open bug on freedesktop please.
