ATI External Event Utility consumes 95 - 100% CPU power

    Question

  • Sometimes when I start up, my system is slowed down to a crawl. If I open Task Manager it shows Ati External Event Utility consuming between 95%-100% cpu power.

    Does anybody know what might trigger this.

    Ending the Process stops the service and returns the system to normal operational speed.

    Original Title: Catalyst CC

  • Hi Irfan,

     

    I have looked on an AMD ganes forum and they say that the External Event Utility is just a HotKey Poller which I don't use anyway so I have disabled it. Time will tell if this solves the issue.

  • Catalyst Control Center should not be installed into Windows 8. It's outdated.

  • On the strength of the most recent messages I have decided to uninstall the Catalyst Control Centre and see what difference I notice, if any. I don't  really know what power optimisations were in the CCC but I doubt I will miss them.


    A week has gone by since I uninstalled the CCC and all is well. I did not use the tools in the CCC so the Windows control of the video is just fine.

    I will mark this an an answer.

  • Look in your Windows System Event Log and see if you have a lot informational events from amdkmdag.

    If so, try changing the eRecordEnable value in the registry at the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Atierecord:

     

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Atierecord]
    "eRecordEnable"=dword:00000000

     

    Setting this value to 0 stops a huge number of events from being written into your system log. Note that every ATI driver update seems to re-enable this setting, so you'll have to remember to re-apply this change if you update the driver.

    Windows 8 Developer Preview. Using a Vista ati driver and Catalyst CC. No such issues on my Vista Home Premium running on the same Acer Aspire 5050 with Amd Turion64 mobile Mk36 processor.

  • You may be right chipvlad, because the drivers released by ATI for WDP recently do not contain Catalyst Control Center.
