Donate@Home

I have a machine that has an ATI HD5870 in the primary slot and an ATI HD 5850 in the secondary slot. All WUs err out on the above condition (reference stderr out below)

Stderr output
<core_client_version>7.0.18</core_client_version>

The HD 5870 is weak and blows out the drivers on all BOINC apps except Collatz. Therefore I created a cc_config fil to prevent Donate at Home from using it -

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<exclude_gpu>
<url>http://donateathome.org/</url>
<device_num>0</device_num>
</exclude_gpu>
<exclude_gpu>
<url>http://boinc.thesonntags.com/collatz/</url>
<device_num>1</device_num>
</exclude_gpu>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

According to the event log, everything appears to work:

Even without the exclude_gpu statements, all WUs erred out. I found it necessary to use the use_all_gpus statement to force BOINC 7.x.x to use all GPUs.

Can anyone give me a logical explanation as to why the WUs are failing?
Thanks.
