Running BOINC 6.4.5 I have been trying a dual graphic setup, to use a non-CUDA device (9500 GT) for my display while running SETI on my new NVidia 260. The reason I am trying this setup is that I had noticed significant graphic (UI) slowdowns under Windows at times and I could not bear it for any of my main machines. Under Win2008 or Vista (64-bit) when the system first cold boots I generally get a 'No CUDA devices found' message. A soft reboot normally then corrects the issue. Any ideas? Thanks.

Install the latest drivers for your card and reboot, after that check your BOINC messages again and you should see:

20-1-2009 20:15:50||CUDA devices found
20-1-2009 20:15:50||Coprocessor: GeForce 8600 GT (1)
20-1-2009 20:15:54|SETI@home|URL: http://setiathome.berkeley.edu/; Computer ID: 4248422; location: home; project prefs: default
20-1-2009 20:15:54||General prefs: from SETI@home (last modified 16-Jan-2009

For you you'll be seeing your card standing there..:)

Kind regards,

Mark Peters.

To boldly go where no human has gone before!

If I'm not mistaken the 9500 GT *IS* a cuda card...

Make sure you update the drivers from the device manager as nVidia's installer doesn't always update both... (If at all?)

Doh! My bad. The second card the monitor is attached to is a 7300GT.

I already had the latest NVidia drivers - 181.20. A cold boot showed 'missinng a CUDA coprocessor' still, repeated dozens of times, and a warm boot got it going again and does show my GTX 260, so the problem still exists from a cold boot. This under Vista Business 64-bit.

I've seen it mentioned elsewhere that there is a bug in bonic recognizing dual adapter set-ups.

It might get fixed when Boinc 6.6.x is released.

---

I installed the 6.6.4 beta. Problem of not recognizing the 260 still exists on 1/2 of the (re-)starts. I swapped out my OS for Vista 64-bit, thinking that it might be related to the NVidia drives, running the same 6.6.4 beta, with the same 50% result.

---

Sorry, correction to above, on Vista 64-bit, the BOINC manager would fail to connect 50% of the time, requiring a reboot to get it going.
