Linux-ATI RadeonGPUをオーバークロックする方法-SapphireR9 270

私はSapphireR9 270（ 正確なモデル ）を持っています。これは270xと同様の速度にオーバークロックできることを読みました。 Linuxでこれを実現するにはどうすればよいですか？

AMDドライバーに付属のamdconfigツールを使用する必要があります。もしあなたがそうするなら amdconfig --help次のようなものが表示されます：

AMD Overdrive (TM) options:
  The following options are used to get and set current and peak, core
  and memory clock information as well as read the current temperature of
  adapters.  By using the "--adapter=" argument the AMD Overdrive (TM)
  options can be targeted to a particular adapter in a multi-adapter scenario.
  If no adapter is explicitly targeted the commands will be run on the Default
  adapter as indicated by the "--list-adapters" command

  --od-enable
        Unlocks the ability to change core or memory clock values by
        acknowledging that you have read and understood the AMD Overdrive (TM)
        disclaimer and accept responsibility for and recognize the potential
        dangers posed to your hardware by changing the default core or memory
        clocks

  --od-disable
        Disables AMD Overdrive(TM) set related aticonfig options.  Previously
        commited core and memory clock values will remain, but will not be set
        on X Server restart.

  --odgc, --od-getclocks
        Lists various information regarding current core and memory clock
        settings.
        Including: current and peak clocks
                   the theoretical range clocks can be set to
                   the current load on the GPU

  --odsc, --od-setclocks={NewCoreClock|0,NewMemoryClock|0}
        Sets the core and memory clock to the values specified in MHz
        The new clock values must be within the theoretical ranges provided
        by --od-getclocks.  If a 0 is passed as either the NewCoreClock or
        NewMemoryClock it will retain the previous value and not be changed.
        There is no guarantee that the attempted clock values will succeed
        even if they lay inside the theoretical range.  These newly set
        clock values will revert to the default values if they are not
        committed using the "--od-commitclocks" command before X is
        restarted

  --odrd, --od-restoredefaultclocks
        Sets the core and memory clock to the default values.
        Warning X needs to be restarted before these clock changes will take
        effect

  --odcc, --od-commitclocks
        Once the stability of a new set of custom clocks has been proven this
        command will ensure that the Adapter will attempt to run at these new
        values whenever X is restarted
  --odgt, --od-gettemperature
        Returns the temperature reported by any thermal sensors available on
        the adapter.

したがって、最初にで有効にする必要があります

amdconfig --od-enable

その後

amdconfig --odsc=coreclock,memclock

たとえば、次のコマンドを実行してASUS7850をオーバーロックしました。amdconfig --odsc=950,1320これは10％のオーバークロックです。

ハッピーOCing！
