	I have two CUDA enabled GPUs on my machine. However, BOINC doesn't want to use the second one. NVIDIA GPU 0: GeForce GTX 260 (driver version 19038, CUDA Version 2030, compute capability 1.3, 896MB, 537 GFLOPS peak) NVIDIA GPU 1 (not used): GeForce 8300 (driver version 19038, CUDA Version 2030, compute capability 1.1, 256MB, 24 GFLOPS peak) I know, the second GPU is slightly less powerfull than the first one, but it's still able to compute data.. Is there a way to make BOINC use the second GPU too? ____________

	Check your BOINC data directory for a file named cc_config.xml. The path to the data directory is listed in the Messages tab of BOINC manager after a reboot. The directory may be hidden by windows and it contains the file client_state.xml (and many others). If you don't have a cc_config.xml, create one using notepad (Editor) and paste <cc_config> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config> into it. When saving, make sure that no other suffix (.txt) is appended to the filename. If you already have created a cc_config.xml file, add the <use_all_gpus> line to the <options> section. After that, select "Read config file" from the Advanced menu or, better yet, restart BOINC.
