I am just starting ATI crunching... so i ask experts for sugestion how to change the option in order to minimize drop of gpuload in counting... The best would be non stop 99% load :)

Now Boinc is crunching one MW task, ends it, and start another...

Now it looks like HD5870 is crunching 900 - 905 WU at 6 hours... so it is 192420 - 193489 c per 24 hours.

Search for this line in the app_info.xml:

<count>1</count>

Change the value to 0.5 (or 0.33 if you want). This instructs the client to start more than one WU. If they got out of sync after some time (you may pause one WU for some seconds to do it manually), you will get a continous high GPU load.

Message 32405 - Posted: 15 Oct 2009, 20:41:36 UTC - in response to Message 32404.  

In other words:

Configuration of the number of concurrent WUs with new BOINC clients (6.10.3 and up):

The included app_info.xml declares the app as GPU app for the new 6.10.x clients. This is done
with a <coproc></coproc> statement. This statement also determines how much of a GPU the
application is upposed to use. If it uses less than a full GPU the client will start several WUs
for each detected GPU. Search for the following lines in the app_info.xml:
 <coproc>
   <type>ATI</type>
   <count>1</count>
 </coproc>
Changing the count value to 0.5 will run two WUs per GPU, a value of 0.33 three WUs.


So I try it tommorow :)

Thnx...

Yes, that works.

Thnx from me also ;)

I am no expert in GPU's, but I would make a friendly comment from the screen shot below :-

GPU load 99%
GPU temp 85C
Fan speed 37%

I would suggest that you increase that fan speed and try to get the GPU temp down to within the 60's range. Rivatuner can change the fanspeed on almost any card.

I can't say I'm an expert on the HD5870 either, but my understanding is that it idles at 40C and rises to 88C under full load, or 90C overclocked. AMD say that it should start to throttle itself at close to 95C degrees.

You're running a bit cold there at 85C TomaszPawel! ;)

Ok i try, and it looks like this:


With 0.5

I try also 0.33 and it works quite well...

In relation to temperatures:

I am not overcloking, the device alone is adjusting its parameters of the work.

I think ATI know what they do in matter of fan speed and GPU temperatures.

If cards fails I will send it to manufacture.... 24 months

I have a small clutch of ATI GPUs and I would be inclined to agree with you ;)

I told you I wasn't an expert LOL! :-) Looks like the latest cards are designed to run at considerably higher temps than a couple of years ago. That is a very good trend, because it means that it shouldn't be necessary to upgrade with after market coolers.

I'm sure there is a place for cooling fans. I have a laptop with a Nvidia GPU which kept turning itself off when trying to do some CUDA crunching. I suspected overheating, so now I have it on a laptop cooling stand with the fans running off the USB and it's been happily crunching Collatz and MW without interruption ever since.

This is to confirm that the zslip domain no longer exists in my ownership and no longer provides redirection to my op apps page.

The link to my optimized apps page is: http://www.brilliantsite.com/milkyway

Misfit has also provided and addition link: http://www.creditsathome.com

I have added a further 'short' link: http://3rd.in/mw

Please use whichever you prefer.

Makes sense.

You can't expect Ice to maintain it after being banned. I think Arcan (sp?) is hosting the apps stuff now.

FYI for the record-Ice's ban is already halfway done. It is not permanent and details will not be discussed in the forums.

In terms of the optimized apps, it is Arkayn I believe, who is hosting.

I believe that the optimized apps are now hosted here: 3rd.in

I'll let you know the password when I can remember it.

Well I joined the rush to beat the rush so I had my stroke at 30 [car accident].
But that was 20+yrs ago so I'm now getting to the age where my mind would be going anyway.
I think it was the woad which swung me...
