Is it only the Nvidia card that Seti@home can use, or can other GPU chipsets be used as well? Also can you use your video card for computation if you are running Linux?

I think that Cuda is a Nvidia only thing. I have been trying to set up drivers for Ubuntu all weekend, with no success....

Ati cards can be used on Milkyway only for now. Nvidia is coming later.

There is a linux port of the S@H CUDA client made by Crunch3r, but it is really buggy and crashes often. I wouldn't reccomend using it.

I tried to get my video Nvidia cards to work in SETI with no sucess and went back to folding on them. How do you set up a video card with SETI and what amount of points can you expect?

My Video cards are 2 9800 GTX, 1 9800 GT and 1 8800GTS

Any help and they'll be back in SETI Very Happy

I'll give it another try.

I have the CUDA drivers loaded and SETI said it recognized the card. The score however wasn't any higher than before using the video drivers. Hopefully, I was just using the wrong drivers.

I'm about two weeks from taking third in folding and then I'll give it a try. Keep checking the stats.

Hmm, I have 4 CUDA cards, Maybe I'll check it out on one workstation this weekend. Smile

Thanks for the help. If you see a jump in my points, you'll know I was successful. Cool

This might be a dumb question, but did you enable the GPU app in your SETI user preferences?

This looks right. Confused

Did you check to see whether the machine you're using is set as "home".

With 6.6.20 you have to check "USe GPU while PC is in use" otherwise it looks like nothing is working....took a bit to figure that one out...

It's under Advancecd->Preferences->Processor usage in the BOINC manager.
