The official nighty build was solid, but the dxva support way back. The newer player is way better so I'm trying to get a beta less problematic

Make sure you don't have "Adjust refreshrate to match video", it's know to be abit unreliable with dxva.

Lister of Smeg Wrote:As elupus says, its the "Adjust refreshrate to match video" & the "Real Fullscreen" that causes the main issues with ATI cards.

I have a HD5450 and using svn30260 the DXVA works perfectly (with CCC 10.5 & "Fake Fullscreen")

But when enabling "Adjust refreshrate to match video", it slows the video down to about 10fps instead of the 24fps that it should be.

Quote:OK guys enough of the hate talk: it's not helping anything here.

I just installed the Flash 10.1 (beta?) release and yes, [for now anyway], it seems to have fixed things up with the 'enable hardware acceleration' problem.

It was really a Flash problem; not so quick cowboy!!

Because guess what?: I left the CCC open and watched the clock speeds of my card during streaming.

Like I mentioned previously on this thread, I could not use my HD5770 card without setting the clock speed to Want_0: 600MHz core/600MHz mem/1.0V AND uncheck the 'enable hardware acceleration' (if I was to stream Flash material at all). If I'd skip that, I'd call in for major audio stutter, image freezes or plain ol' system crashes -fullscreen or not. So that means that my frequencies would stay at a minimum of 600MHz no matter what.

What happens now? As soon as I start streaming a Flash video (on justin.tv for example), my frequencies change to 400MHz core and 900Mhz memory.

So, surprise! Was it really and purely a Flash problem? I don't think that the answer is that simple and here's why:

It seems that Flash is now overriding my "up-clocked" CCC profile's settings.

(I don't want to use the term "over-clocked" here because I am not going over my default max clock speeds here; again, I'm just increasing it's minimum operating frequencies and 'Idle'.

In my case, Flash is now actually setting the core speed a tad slower than I set it to and increases the memore clock speed. But that is higher clocks than the default CCC settings - details here:

Default Want_0 (Idle): 157MHz core, 300MHz memory and 0.95V

Default Want_1 (2d mode) - maybe the case if Flash is running): 600/1200/1.0V

My Profile Want_0: 600/600/1.0V

My profile Want_1: 600/900/1.0V

Flash 10.1 frequencies when streaming: 400/900/??V

(I could find out the voltage with GPU-z maybe but who cares for now?!).

As soon as I stop the streaming, the numbers magically return back to my profile's settings.

So now, tell me:

granted that CCC is an essential ATI thing to use if you want to fully take advantage of your card and its power saving features -for example- (and by that consider it "THE" driver), having Flash to override ATI's CCC instructions in order to run adequately defies the definite 'Flash is at fault' argument -in my mind anyway.

i.e.: ---> This looks to me that it is Flash fixing ATI's software/problem.

Thoughts on this anyone?

And no schoolyard fanboys' talk please ;p

Quote:Hi there,

I have similar audio problems with my HD5770 as well.

I have a ticket opened with AMD's support on that and it has recently been escalated. I am impatiently waiting for their answer on it.

In my case, there is even more than the Flash streaming problems.

Yes, disabling the hardware acceleration in Flash helps the problem and give better streaming quality (less picture freeze and audio distortion), but the real problem is somewhere else with the way the card down/up-clock and /or change the voltage - hence: the way CCC manages the cards settings depending on the laod on it. I am categoric on this one.

There are now tons of forum threads on this topic and there is something going on for sure. I had to troubleshoot for a full 3 days before finally finding a temporary solution. I just can't use my card without having to tweak it; otherwise, my audio start freaking out [I'm not using the Hi-def audio over the HDMI thing yet], or I get freezes in streaming and/or while during desktop tasks.

I since then did more research and found post dating back to 2004 on this clock speeds/voltage issues.

Anyway, I'll have more on the topic soon (hopefully) once and if I get a useful reply from AMD.

But here's what worked for me:

I have to create a profile and edit it so that the card will never have its core and memory downclock below 600MHz.

To do so, you have to create a new profile in CCC, save it and do not activate it yet. While your are there, create a second one that you will call "DEFAULT" or something else explanatory to reverse your changes if needed. Now, do a Windows search for the name or your profile [the one you want to use to tweak] and make sure to include the hidden files and folders. The file should be a [your profile name].xml file type. [you might have to repeat the search a 2nd time sometimes to see it].

---> OR go check under: C:\Documents and Settings\[your user name]\Local Settings\Application Data\ATI\ACE\Profiles

Open that .xml file with notepad and there you will see the values that you can tweak.

OK, let me stop right here! I want to say that this is done at your own risks and I don't want to be accused on any problems that may or may not occur. I don't want AMD to accuse me of reverse engineering or software hacking either. These changes in settings are just tweaks that allow me to use their card and if this can help others; then let's be it. Basically, I have to do this to use the card or I have to RMA it - so give me a break....!!

By default for my HD5770 profile looks like this:

<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="15700" />
<Property name="Want_1" value="60000" />
<Property name="Want_2" value="85000" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="30000" />
<Property name="Want_1" value="120000" />
<Property name="Want_2" value="120000" />
</Feature>
<Feature name="CoreVoltageTarget_0">
<Property name="Want_0" value="950" />
<Property name="Want_1" value="1000" />
<Property name="Want_2" value="1125" />

And to fix all my problems, I have to change it to this:

<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="60000" />
<Property name="Want_1" value="60000" />
<Property name="Want_2" value="85000" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="60000" />
<Property name="Want_1" value="90000" />
<Property name="Want_2" value="120000" />
</Feature>
<Feature name="CoreVoltageTarget_0">
<Property name="Want_0" value="1000" />
<Property name="Want_1" value="1000" />
<Property name="Want_2" value="1125" />

So basically pushing the card NOT to 'downclock' to the normal power saving Want_0 mode and forcing it to iddle at 600/600MHz/1V.

Finally, you can use the CCC option to enable the Hotkeys binding and set it so you can swithc between your tweaked and default mode on the fly. In my case, I cannot go back to the normal profile without getting my audio/video problems reappearing within seconds...

And that means that in order to just be able to use that card, I have to let go of (almost) all it's power saving advantages: the main reason that brought me to chose that card over one of the other major competitor in the first place. But this downclocking issue is real for me and is clearly not a Flash only problem. I've never had to disable the HW Flash acceleration to get proper streaming on my previous green cards either.

So there you go! Sorry for the long post, but hopefully this will be useful to some and maybe also push AMD/ATI to work on a solution. I want to be able to use my card without having to hack [sorry! tweak] it and I also want to see a low power consumption: up to to the level that they commercialize it toward.

Maybe, only maybe, could it just be a matter of changing CCC to only downclock to 157MHz core/300MHz mem ONLY after a longer low GPU load period; see 1, 10 or 20 minutes maybe....

Peace out!

Most likely the same problem as with the MSI board, but Gigabyte actually cared to fix it. Update to the latest motherboard bios.

I've been using build r27705 now for a few months on my Revo 3610 and last night I thought I would try the latest build. After seeing some of the bugs I decided to go back to r27705 but now my option to select DXVA is gone. I've done a complete uninstall including profile, reboot, reinstall a couple of times with the latest build and/or r27705 now with no success and I can't figure out what I'm missing here. I'm sure it's something simple but I'm at a loss. Any ideas?


Edit -

Nevermind, I figured it out. I thought I had seen a single menu option to enable DXVA so I was skipping right past the render choices. I knew I'd feel stupid.
