I just installed a new nVidia GT640 in one of my machines and it won't run the opencl projects. It is not an SLI capable card. Running BOINC Client 6.12.34. Also running Win XP 32 all updates. Installed latest drivers from nVidia. The card shows up in Device Manager as operating. I think I am missing something. Hoping it is not because it is not SLI capable.

SLI has nothing to do with it but being "dual precision" does and I can't find a website where it says the 640 is. If it is not that is why it won't work here at MW.

As a test take the card to the project DistRTgen and try it there:
http://boinc.freerainbowtables.com/distrrtgen/index.php

You can attach thru your Boinc Manager, it is on the list in the newer versions. BUT do NOT change anything just attach it there and see if it works, keep the cache SMALL as the units are under an hour and it can download a ton of them if you aren't careful. If it works there it is not your setup but your lack of dual precision I believe. This is what you should put in the project attach box:

Yes, the GT 640 can run OpenCL tasks (mine runs a WU in about 22 minutes), but you need Boinc 7.0+ to do this. AFAIK Boinc 6.12.34 doesn't work with OpenCL.

IF you do this do NOT go past Boinc version 7.0.25 as that didn't work for me at all! You can get Boinc here:
http://boinc.berkeley.edu/dl/?C=M;O=D

I have an Nvidia 560 Ti and anything past 7.0.25 gave me the same error you are now seeing. Sorry I didn't even think of earlier versions having issues too! One thing when you use version 7.0.25 MW will run in 'high priority' mode and there is NO WAY to change it. I was only running ONE project and it it STILL ran in 'high priority' mode. IF you wish to run two MW units at once try this:

<app_info>
<app>
<name>milkyway</name>
</app>
<file_info>
<name>milkyway_separation_1.02_windows_x86_64__opencl_nvidia.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>milkyway</app_name>
<version_num>102</version_num>
<flops>1.0e11</flops>
<avg_ncpus>0.05</avg_ncpus>
<max_ncpus>1</max_ncpus>
<plan_class>cuda</plan_class>
<coproc>
<type>NVIDIA</type>
<count>0.5</count>
</coproc>
<cmdline>
</cmdline>
<file_ref>
<file_name>milkyway_separation_1.02_windows_x86_64__opencl_nvidia.exe</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>

Save that file as a .txt file in Windows using NOTEPAD, do NOT use a word processing type program as they add stuff Boinc doesn't recognize. Save it as app_info.xml and put it in the C:\program data\Boinc\projects\milkyway in Windows7.

IIRC if he uses the app_info, he can stay with BOINC v6.
