ATI driver question...  

The video card in this system is ATI Radeon HD 5570 and the driver version is 8.8.21. It works just fine; however, the driver is spamming the event log with informational messages like these:



At this forum, this is how these logs explained, quote:

DVD_OV stands for DVD Overlay. OPM stands for Output Protection Mecanism. HFS stands for Hardware Function Scan. This log/error is the cards DVD screen overlay failing it's High-bandwidth Digital Content Protection (HDCP) check over DVI/HDMI.

Disabling AMD External Events Utility service does not get rid of these multiple events per second; however, the link suggested registry fix did.

And again, in my other system with the Asus P7P55 motherboard, with ATI Radeon HD 5850 video card, drive version 8.801.0, there are no event ID 62464 informational messages. I am not certain that the driver version would make that much difference.

The major difference between the two system is the OS. The machine with these event ID messages is Windows 7 64-bit with SP1, while the other is the same without the SP1. I vaguely can recall some discussion about SP1 adding High-bandwidth Digital Content Protection (HDCP), which can contribute to some of the issues I've experienced with this new PC. If the HDCP had been added, is there a way to remove it from the system? Well, short of starting fresh and don't add SP1.
Thanks in advance....

Fascinating!

Just looked at my own system, which is Win7 x64 SP1 and has an HD4670 running with Catalyst 11.3 (and an old 4x3 19" IBM P92 CRT monitor connected using VGA), and it's producing the same nonsense in Event Viewer.



I looked at the other forum discussion on this same subject, and it would appear that the suggested Registry fix is apparently the only real way to stop this:

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

To me (who doesn't know anything about this logging for general use and other situations, much less why AMD is doing this) it does seem that disabling logging universally for ATI (which is what I think this change does) seems a bit extreme. Would seem to be forcing the loss of information for other situations that might be useful.

But I may just be overreacting here. Personally I have NEVER even looked into this particular set of Event Viewer information for anything... and doubt that I ever will again! And it does seem to be only for ATIeRecord... so I'm sure it's fine.

Anyway, it does seem wrong what is happening right now, and the other forum members seem to be pretty knowledgeable. So I will apply that fix on BOTH of my systems (including my other system, also Win7 x64 SP1 with an HD4850 in it and also Catalyst 11.3, with two-monitors 24" 16x9 LCD and 21" 4x3 CRT on extended desktop, both connected with DVI) and what I'm guessing is ALSO logging like crazy).

All there appears to be, are the 4 registry fixes

Only the one fix, to "current control set", seems to be needed to get the job done.

I only made that one fix and the logging disappeared.

I've looked at the logs for two reasons....

The ATI logs are recorded on the "C" drive, which in my case an SSD drive; at least until they were they've been moved to a platter based drive. Having the ATI driver writing these useless, same non-descriptive six entries per seconds is spamming. Not to mention its impact on performance in general and the life of the SSD drive.

The other is the HDCP component that the log entry refers to. Why are these logs showing up on Windows 7 Professional SP1, but not on the system without the SP1? I understand that the High Definition Content Protection is a "must" nowadays; however, it should not negatively impact system performance. Nor should it continuously keep verifying that the content protection is operational for the DVD, much less logging it all the time.

Turns out modifying only the "CurrentControlSet" registry entry was NOT sufficient to stop this stuff.

Searching on the AMD Forum, it seems you really do need to modify ALL of those ControlSet versions of ATIerecord (not minding if you don't have all of them, like ControlSet003).

Furthermore, there are additional entries for ATIerecord that need to be set to 0, so you need to do a "find" and "find next" repeatedly, and set each one you find to 0.

=========================================

For Windows 7 Click Start then type regedit
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Atierecord]

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Atierecord]

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\Atierecord]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atierecord]


Right click on eRecordEnable and modify the value to 0 for all of these, don't worry if you don't have the same amount of keys.

After looking more there's more ATIeRecord entries than these, so you might want to use the search function, Edit at the top of regedit, then Find - type in atierecord (dont forget the e in the middle of ati and record). Then hit F3 to "Find Next" and keep doing that until you find every atierecord key and set it the value to 0.

===================================

This seems to have finally turned off the event logging for me.

We can agree to disagree about the nature of the reasons...

The fact is that the High Definition Content Protection negatively impacts the performance of the system and in extreme case, it can results crashing some of the systems.

The problem is that the there isn't much information available for the HDCP, both MS and AMD are tight lipped about this service and as such, people look for hardware and/or software failure for systems that have issues. They may spend countless hours for testing the memory, reinstalling their system, running torture test, etc., just to learn that HDCP is the cause of the issue.

I guess that's how MPAA and others prefer to "control" computers; as little information as possible...
