You're getting the wrong application sent to the wrong card. You should be getting the 6.08 (cuda) or 6.09 (cuda23) application for the 9800 GT, not the more specialized 6.10 (cuda_fermi) application, which is only for Fermi and above style GPUs (GT4xx and above).

Perhaps wise to take the 9800 GT out, or not use it for crunching in combination with the GTX 960. You can exclude the use of certain GPUs through BOINC its client configuration file.

Example given:

<cc_config> <options> <exclude_gpu> <url></url> [<device_num>1</device_num>] [<type>nvidia</type>] </exclude_gpu> <exclude_gpu> <url></url> [<device_num>1</device_num>] [<type>nvidia</type>] </exclude_gpu> </options> </cc_config>

The above, when saved in your BOINC Data directory, will exclude GPU number 1 from being used at Seti and GPUGrid. You can see which device number the 9800 GT has when you start up BOINC and check the start-up messages in the Event Log (CTRL+SHIFT+E). Numbering starts from device 0 onwards.

Ancient Astronaut Theorists say that they believe in them... Why don't you?
