    HD2400 / rv610 power managment

    kuz

      Hello,

      i'm using linux and have desktop with HD2400. Currently HD2400 is very hot. No X11 is running, just plain console. I'm searching a way to cool down my HD2400. I have 42589_rv630_rrg_1.01o.pdf, but there is'nt enoung information about power managment.

      I tried to setu up GPU_COUNTER_CLK to 1 in GENERAL_PWRMGT register, but this seems doesn't help.

      Changing SCLK_PWRMGT_EN in SCLK_PWRMGT_CNTL and MPLL_PWRMGT_OFF in MCLK_PWRMGT_CNTL doesn't help too.

      Is there any recomendations/documentation how to setup device for low power mode?
