Strange Clocks

[Mr. Pedantic]

My 4870 idles at 200MHz Core and 500MHz Memory. When I'm folding (which is basically the whole time my computer is on) it ups to its normal 3D clocks: 750/500. However, today I was playing a blu-ray - Wall-e, if you're interested - the 4870 adopts another set of clocks - 500MHz core and 500MHz memory. Coupled with the GPU load from the blu-ray, my folding performance almost exactly halves.

So my question is, is there a way for it to change the blu-ray clocks to the 3D clocks - that is, 750/900? I should note, that my GPU for some reason resists all attempts to change its clocks manually; not just overclocking, but underclocking as well; even 550/600 ended in VPU recover with Far Cry. This goes for CCC, RivaTuner, and ATITool.

Thanks for any help.

Create a profile in the CCC for your card.
Locate that file - I think it is the AppData folder for Vista.

Modify the values you want to change for all three card states.
(You can see the card to always stay at a certain core/memory mhz)

Then re-load / re-apply that profile in CCC and it will do what you want.

just disable dxva in your media player.. should solve the problem.. ive noticed this with my cousins laptop as well after putting the 9.12 hotfix drivers on it.. shits laggier then hell and now uses completely random clocks from what it use to be when running hardware acceled media.. im about ready to just go back to the original toshiba drivers even though it will lose about 5-8fps in MWLL(crysis mod)..

 

[Mr. Pedantic]

I'm using Cyberlink PowerDVD to play Blu-rays...how do you disable DXVA in that? I've tried turning off hardware acceleration, but it won't let me.

And I've never tried creating a CCC profile before, what do I have to do?

 

[sirmonkey1985]

hmm interesting that it wont let you turn it off... cant help with the profile stuff though never messed with any of that..

I was afraid you would ask that.

Do a search for CCC Fan control. That will get you threw creating the profile and the editing part. Instead of editing the fan, you want to focus on the core/memory speed.

When looking at the XML file, you will see your speed settings.
(C:\Users\Administrator\AppData\Local\ATI\ACE\Profiles) -- where mine is located
---I am running Server 2008 so your location will be slightly different

Here is what you will see at the top of the XML file (Open in WordPad/Notepad)

      </Group>

What you want to do is replace "Want_0" and "Want_1" .. with the the values of "Want_2"

In my case, it would look like

        <Feature name="CoreClockTarget_0">
          <Property name="Want_0" value="65000" />
          <Property name="Want_1" value="65000" />
          <Property name="Want_2" value="65000" />
        </Feature>
        <Feature name="MemoryClockTarget_0">
          <Property name="Want_0" value="100000" />
          <Property name="Want_1" value="100000" />
          <Property name="Want_2" value="100000" />
        </Feature>
        <Feature name="CoreVoltageTarget_0">
          <Property name="Want_0" value="1123" />
          <Property name="Want_1" value="1123" />
          <Property name="Want_2" value="1123" />

Notice I change the "50000" to "65000" on both top sections (Keeps GPU Core @ 650mhz
Notice I change the voltage to "1123" from "1046" in both lines.

Then go into CCC and re-apply that profile.
Should fix your issue!

 

[Mr. Pedantic]

I see the <Group> right at the bottom.

All my values of "Want" are the same:

And I don't have any profiles in the Catalyst Control Center.

I had the same problem when running Vista Media Center (I haven't tried it on Win7 to see if it does the same). Once I started watching my recorded TV shows my 4870 would revert to idle 2d settings. I couldn't find a setting that would prevent it, Catalyst profile or not. I ended up just killing the FAH GPU client and restart it once done watching TV as it would EUE if I kept it running.
