I installed lastest vista nvidia drivers. Latest boinc, and even driver excluside older cuda drivers. Graphics card is installed properly. But Boinc says no cuda device. Nvidia 9800, Windows 7, Q9550, installed. Installed optimized using Installer.
Thank you

Hi, can you give us some more details? Your information is a bit sketchy.

For your information, I'm running Windows 7 64-bit, with Boinc version 6.6.36, on a 9800GTX+ 512Mb, with the Lunatics Unified installer with v505 AP added, and Nvidia drivers 186.18. I've got a Phenom II 955 at 3.6Ghz and 4Gb of Ram. I've been successfully running 6.03 Multibeam and 6.08 (cuda) tasks for several days when I can get work down and uploaded. I've even got a solitary v505 AP waiting to go.

Do you get error messages? If so, what do you get? Is it just no cuda device?

Have you tried getting GPUz? It might give you a bit more info on your graphics card. How much graphics memory have you got? 256Mb or 512Mb? That might be a limiting factor. This machine has 512Mb graphics, my other machine has 8600GTS with 256Mb but seems to be running cuda successfully as it is on Windows XP home with fairly low resolution of 1024x768.

Hope some of this helps. But you need to give more information if you want others to help you.

[EDIT - Just a thought. Not done something silly like forgot to connect the extra power cables to the graphics card? /EDIT]

regards, Gizbar.

A proud GPU User Server Donor!

For your information, I'm running Windows 7 32-bit, with Boinc version 6.6.36, on a 8800GT 512Mb, with the Lunatics Unified installer with v505 AP added, and Nvidia drivers 186.18. I've got a Q9550 with 2GB. I've been successfully running 6.03 Multibeam and 6.08 (cuda) tasks for several days when I can get work down and uploaded.But Cuda no go.

Do you get error messages? If so, what do you get? Is it just no cuda device?
It says no CUDA device Installed

512mb card at 2560x1600.

Other Windows XP runs cuda and cpu work fine.

I have tried Windows 7 drivers 186.18 but wont work at all, Then installed cuda 2.2 185.85.

I haven't tried W7 yet but with Vista you can't install BOINC as a service (protected application mode in the installer). If you do then BOINC doesn't detect the CUDA device - could W7 still be the same? XP did not have this problem.

You could be my hero.Ill unistall and try again.

It says it in the BOINC Installer for Windows Vista and above not to install it as a service when you want to use CUDA. A little reading instead of dumb clicking goes a long way.

And besides, it's saying in the Seti CUDA FAQ, which is a sticky thread already, "Check to make sure BOINC isn't installed with the Protected Application Execution option. This option is incompatible with CUDA." .. although that's false information for Windows 2000 and XP.

According to this thread my system should be working, but it is not. I just setup the release candidate, 7100, with all patches, downloaded the latest windows 7 from nvidia: 190.38_desktop_win7_winvista_64bit_english_whql and installed boinc 6.6.36 64bit under my account (not as a daemon) but I cant make it work with my 9800gtx+ It just does not see it.

what I have tried: Removed myself from administrator group but could not then run the manager. Tried installing from a non-admin but it wont install unless admin. I just put system together yesterday with XP (it worked fine) then decided to go for 64bits and windows 7.

There is nothing informative in the event log. I do not see any of the nvidia tools that normally get installed as on my two vista 64 systems. All I see is the nvidia's "3d vision" under All Programs.

thanks for looking

Got it working. I uninstalled, then reinstalled and the cuda device was recognized. Go figure!
