Heya

Sorry for another GPU thread.

I have a Win8 x64 PC running BOINC that isn't detecting my GeForce GT 640. I know it's not a powerhouse but it has CUDA and it'd be nice to get it churning a long as well.

I can't see anything obvious in the logs, but am I missing something because I'm on Windows 8?

Many Thanks

Please post your BOINC start up messages from Event Log (CTRL+SHIFT+E). The first 20 to 30 lines will do.

Thanks for the reply :-)

There you go:

You installed in 'Protected Application Execution' or 'service' mode. GPU crunching is not possible, because of the new driver security features in Windows 7/8. Uninstall BOINC (your data, like CPU tasks, is kept safe), then reinstall but uncheck the PAE option: you need to click through to the 'Advanced' page in the installer to do this.

Ah silly me, it even says so in the blurb I just skipped through x)

Many Thanks
