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

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.

Answer 5

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.

Answer 6

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 It's outdated.

Answer 7

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

Answer 8

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.
