I own two R9 295x2 cards, and after updating to the latest Omega driver (14.501.1003), only one of the four cores is available for work.

The event log appears to indicate that the other three cores are ignored by configuration, but I don't remember changing anything other than the GPU driver.

I can post the full clinfo upon request. Anyone else see this same issue, or have any ideas? My system used to absolutely blast through work units, but now it's just kind of puttering along at a leisurely pace. :)

Check the contents of the cc_config.xml file in the data directory (default at c:\programdata\boinc\), and else post those contents here.

Interestingly enough, I don't see that particular file listed, only the following:

C:\ProgramData\BOINC\get_current_version.xml
C:\ProgramData\BOINC\get_project_config.xml
C:\ProgramData\BOINC\global_prefs.xml

C:\ProgramData\BOINC\daily_xfer_history.xml

What might I be missing here?

As an additional data point, I have confirmed that rolling back to amd-catalyst-14-9-win7-win8.1-64bit-dd-ccc-whql does allow all four GPU cores to simultaneously do work as it used to. Re-upgrading to amd-catalyst-omega-14.12-with-dotnet45-win8.1-64bit again results in only a single GPU core doing work.

Here is the full clinfo output from the system while running the new driver:

Had to add the following to the cc_config.xml.

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

Still curious as to why the driver update changed the behavior though. Strange.

---

Your first post show 3 times "(ignored by config)"
That is why Ageless asked to check cc_config.xml

At that time the "(ignored by config)" lines imply that you have in cc_config.xml some lines to:
<ignore_ati_dev>N</ignore_ati_dev>
     ignore (don't use) a specific ATI GPU. You can ignore more than one.


But yes, if the GPUs/video cards of the same vendor are not reported as identical (in your case OpenCL 2.0 vs 1.2 and 4096MB vs 3072MB)
you need <use_all_gpus>1</use_all_gpus>

Maybe the current BOINC version say "(ignored by config)" even if that means the default of <use_all_gpus>0</use_all_gpus> is used.
(If no cc_config.xml exist BOINC acts using defaults)

Maybe the current BOINC version say "(ignored by config)" even if that means the default of <use_all_gpus>0</use_all_gpus> is used.
(If no cc_config.xml exist BOINC acts using defaults)

Good question.

No, according to the source code, the ignored by config is explicitely mentioned when the user has the <ignore_X_dev> set in cc_config.xml
When there is more than one GPU in the system and they're (all) different so that only the best GPU is used, the message on the other one(s) is not used.

Example given: http://boinc.berkeley.edu/dev/forum_thread.php?id=7988
