Greetings!
I'm running Boinc 6.6.26 and have a Nvidia 260 and a have added a Nvidia 250 int this (4720228) machine.
When I start up boinc it now sees both cards as a 250 and says one of them is not used. The GFlops for the 260 was much higher than the 250 but both are now rated at 84GFLOPS.

Any ideas how to enable the new device and how to make it see the 260 with its' higher gflops as the right card ?

And after the spanking comes...



Ni !

Try to use older BOINC like 6.6.20.
New ones seems have very doubtful "feature" to enable only best card on host....
I consider it as direct act of sabotage ;)

Changing back did fix the problem, I agree, the new "feature" really bites.

It is known design feature. Idea is sound in theory as it will prevent using lesser card so video redraw not effected like when pure opt out.

To use all GPU's add the line <use_all_GPUs> to cc_config.
Here is a template from Raistmer.

<cc_config>
<options>
<ncpus>NUMBER_OF_LOGICAL_PROCESSORS+NUMBER_OF_GPUs</ncpus>
<use_all_gpus>1<use_all_gpus>
</options>
</cc_config>

For 6.6.20 and newer use this one instead, As <npus>NUMBER_OF_LOGICAL_PROCESSORS+NUMBER_OF_GPUs</ncpus> is not needed with 6.6.20 or Newer.

<cc_config>
<options>
<use_all_gpus>1<use_all_gpus>

</cc_config>

Sorry, thanks!
Using teamwork mod here, as it's works the best for me. Forgot all about using stock cuda scheduling.

My recent hellish move to 6.6.20 had similar issues, with Boinc only utilizing the fater card. I deinstalled the slower card, upgraded the NVIDIA drivers to the latest version (18250) then reinstalled the slower card. The NVIDIA drivers replaced were quite upto date being only about four or five weeks old.

6.6.20 is now happily using both cards with the new driver. [See snipped from the log file.]

Same problem here.
rollback to version 6.6.20 fixed the problem.

Had the same problem with "not used" on my 2nd card with 6.6.28. Had been using 6.6.20 but was reading on the GPU Grid boards that 6.6.23 was better. Im now using 6.6.23 with no problems reading both cards.

It was introduced in 6.6.24. After complaining Dr A revised it to allow a 30% variance in memory from the 1st device to any others. If they are totally different then you need to either drop back to 6.6.23 or use the cc_config flag.

Personally i'd suggest 6.6.23 over 6.6.20 as it has a couple of cuda fixes. It depends on if you want to run the official version or the development version.
