I do not have this xml file in any of the BOINC folders. How can I add cc_config.xml?

---

Open notepad, copy&paste the lines from Ageless's post and save them as file cc_config.xml to the BOINC data directory. Make sure that no .txt suffix gets appended by notepad.

Gruß,
Gundolf

I'm also getting this issue. Here's my (editted) log output with BOINC version 6.10.7 on Win XP after adding the debug flag in a cc_config.xml file.

I'm using the Nvidia driver version 6.14.11.8120 - 181.20_quadro_winxp2k_international_whql.exe

I'll install the new drivers and give it another go.

All right. The new Nvidia API that BOINC 6.10 uses has a minimum driver set of CUDA 2.2, 185.85.

If your present drivers are below this version, update first.
If your present drivers are below this and they're the last available for your hardware, you cannot update to 6.10; stay at the last 6.6.x version for your OS.

Spread the word.

Just to confirm that the latest nvidia driver (version 191.00) fixed it for me on Win XP.

Thanks,

Tim

Just a note, but I am running the latest 6.10.17, Win7, and as long as I do not install it as Protection application execution, it is recognizing the GPU, if I install and select Protection application execution mode, I end up with the "No CUDA capable GPUs found."

For me, the solution was NOT TO use Protection application execution mode and the GPU is there all the time.

In my WinXP workstation(s), either mode works just fine.

Did you even read this thread? I explained in this post in this thread why that is.

By default, the later BOINC versions will not install as a service (the protected application execution option), at least for the Windows x64 applications. The user must override the default installation to install BOINC as a service - DON'T DO THIS!
