My GPU is NVIDIA FX880, but BOINC look like didn't using it, just using the CPU, why? And what should I do?

Can you post the first 30 lines of your BOINC log?

Best guess is that BOINC is installed as a service which will not recognize the GPU.

...or the wrong drivers are installed.
Make sure you are using the Nvidia or Gforce drivers (which have Cuda) NOT the Microsoft ones (which do not have Cuda)

Thank you very much! But my driver is NVIDIA's one

Thanks for your help！
No usable GPUs found, I don't know why..
My GPU is NVIDIA FX880M with CUDA, and I installed NVIDIA's drivers.
eh,I come from asia so my English isn't very well.

 
The RED have to be on these:

Which means You intentionally (by checking Option manually) installed BOINC as a service. (this was already noted by arkayn)

Now Uninstall BOINC - this will NOT lose tasks or Settings/Preferences - just Uninstall, do not delete anything manually.

Install BOINC again but now Uncheck "Service Install"
(as BOINC installer remembers your last choice you will need to Uncheck this manually)

Install BOINC again but now Uncheck "Service Install"
(as BOINC installer remembers your last choice you will need to Uncheck this manually) 

And to do so...

In the third screen of the installer, click Advanced:


Then uncheck the mark on "Service Install":


And continue installation.

It's not possible to run BOINC as a service and use the GPU, because Windows services run in their own session, and therefore cannot reach drivers installed by the user. So then BOINC cannot detect what kind of GPU you use.

For any of this to change, you'll have to tell Microsoft to change this.

Thank you very much! I'm trying again~
