I have a Q6600 PC with an Nvidea 8600 GT card, running Windows Vista Premium 32 bit.
I downloaded and installed the Nvidea driver version 181.20, and in the properties of the driver I see nvcuda.dll present.
But BOINC doesn't detect the CUDA device... :

Does somebody know what's going wrong here?

Thanks a lot in advance,
Eric

OK, in another thread I found out that CUDA doesn't work on Vista if BOINC is installed in protected mode.
So it looks like I'm out of luck, and I may forget about CUDA...

Greetings,
Eric

Well, do you need to run in protected mode then? There's no way around it?
As else you can uninstall and reinstall in 'normal mode'. Even try one of the newer BOINC versions, like 6.6.0 (development version).

Hello Eric,

I've a Q6600 too and run a 8600GT, but I installed the latest driver for NVIDIA for Vista 32bit. Running on:

All 4 cores are crunching Astropulse now, didn't finish one yet but takes about 40 hours to compleet 1 task, now still 20 hour before completion..:)

Yet on the grafix I cannot make any sense out of it, but cannot view on grafische weergave. If I do, we will see the standard SETI layout with 2 huge white boards on it. I'm thinking to buy me a NVIDIA 260 card soon..:)

Hope I helped you some bit.

Kind regards,

Mark Peters

To boldly go where no human has gone before!

Hi,

I'm not the only one who uses that computer... my daughters also use it.
And if BOINC isn't installed in protected mode it will only run when I'm logged on with my own account. While running it in protected mode ensures that it's always running, no matter who is logged on (even when noone is logged on...).

So I'll stick to "no CUDA"... like this it will do a lot more work.

Greetings,
Eric
