I have just inslled BOINC and it's using my GTX 460s, but not my GT 430 and GT 520 cards. What do I have to do to get it to use these please? I realise they will not be as fast as the GTX 460s, but they are still going to be faster the the CPUs. When I checked their CUDA Compute Capability both are V2.01 which is the same ad the GTX 460s.




Looking in the event log it says:

26/01/2012 11:21:32 | | NVIDIA GPU 0: GeForce GTX 460 (driver version 28562, CUDA version 4010, compute capability 2.1, 1024MB, 684 GFLOPS peak)
26/01/2012 11:21:32 | | NVIDIA GPU 1 (not used): GeForce GT 430 (driver version 28562, CUDA version 4010, compute capability 2.1, 512MB, 179 GFLOPS peak)
26/01/2012 11:21:32 | | NVIDIA GPU 2: GeForce GTX 460 (driver version 28562, CUDA version 4010, compute capability 2.1, 1024MB, 684 GFLOPS peak)
26/01/2012 11:21:32 | | NVIDIA GPU 3 (not used): GeForce GT 520 (driver version 28562, CUDA version 4010, compute capability 2.1, 512MB, 104 GFLOPS peak)

How do I overide this?

Thanks Bill. All the GPUs are now busy.

Looking at my Computers page though it's reporting

[4] NVIDIA GeForce GTX 460 (1024MB) driver: 285.62

BOINC will do that. It just reads whatever card is in slot 0 and uses it as the default for all the others.

That's only cosmetic (the most capable GPU is reported only on the web site)

But the SETI CUDA app reports them OK in Stderr output of any completed SETI CUDA task, e.g.:

Wow! Are you Ray Hinchliffe?!

I use SIV for years and we had some conversation (~50 emails) over the years.
(I'm the same 'Bil Bils' from emails to you)

I even 'advertised' ;) your FREE program here:

Since you are excellent programmer I will not obey the rule to not suggest 'complex' things to 'New member'

You may try the Optimized Applications by 'Lunatics':

(They are not only faster but also more mature)

Get the appropriate (32 and/or 64 bit) Windows Installer v0.39
It contains all the needed files.
(You may use 7-Zip to see the contents of the Installer)
