http://boinc.berkeley.edu/wiki/Client_configuration

The configuration is read from a file cc_config.xml. If this file is absent, the default configuration is used. To create or edit the file, use a text editor such as Notepad, and save it as cc_config.xml in your BOINC Data directory.

Options
<use_all_gpus>0|1</use_all_gpus>
If 1, use all GPUs (otherwise only the most capable ones are used). Requires a client restart.

I'm about sure that the "ignored by config" message only occurs when the user specifically ignores the GPU via cc_config.xml
When two different Nvidia GPUs are in there, both CUDA and OpenCL on the weakest GPU will state "Not used".

So instead of just adding use_all_gpus, also check further down in your cc_config.xml file if you are ignoring GPU1. More specifically via the ignore_nvidia_dev option.
<ignore_nvidia_dev>N</ignore_nvidia_dev>
Ignore (don't use) a specific NVIDIA GPU. You can ignore more than one. Requires a client restart.
