Hi guys. I bought a GTX480 and wanted to test it's crunching on SETI, but I'm getting a ton of errors with it. A few WUs have completed successfully, but most are erroring out with a -9 "The number of results detected exceeds the storage space allocated."

They only run for about 15 seconds and complete. I have hundreds of these pending. I have several under "Errors" and many under "Validated".

I was getting this using the latest BOINC client, and then I upgraded to the Lunatics optimized client and got the same result. I chose the "easy" installation for the lunatics client.

I am running the 480 on a liquid cooled setup and temps are in the 30s when this is happening. It happens on stock clocks and overclocked.

Running the latest Nvidia drivers and on Win 7.

Let me know if I am missing anything. Please help me out as I'd love to do some more crunching with this thing!

Thanks!

Update: The vast majority of these are going under Invalid. I check other users with the same WU and they are being marked valid and getting credit.

it would be easier if we could see your computers. We could then see what Driver version you are running and other important items that could help diagnose the problem you are having

Not sure if this is how to post it, but this is my computer with the CUDA device.

I'm not sure why you aren't able just to unhide your computers. We can get a few more details about how you and what you are running on that system. It doesn't give us any sensitive inforamtion like ip or computer name. I'm still wondering what driver version you are running and that is available to us if you just unhide.

It's also available from the link in the post you answered to: http://setiathome.berkeley.edu/show_host_detail.php?hostid=5393866.

It says: NVIDIA GeForce GTX 480 (1503MB) driver: 19741

I can't find the spot to unhide it.

I've seen it in the past, but can't find it now. I'll look again.

I've set this:

Should SETI@home show your computers on its web site?

To yes, but that computer is offline and won't "update" to the project until I get home later today. The computer details are in the link I posted above.

The 197.41 drivers are the latest certified drivers from Nvidia on my platform Win 7 64bit.

That isn't necessary, since it's an online preference. It just takes some time until the change gets visible to all.

Your computers are visible now.

Not to my knowledge. Is this a prerequisite for running? I can do that when I get home and see if it makes a difference.

But my GPU is waiting for work.

First off, the BOINC client you use doesn't correctly recognize Fermi cards, which your GTX 480 is. For the moment you'll have to wait for the next recommended version to be released as the previous one that did recognize it correctly was pulled due to a big bug with hanging GPUs and it continuing to request work for the GPU that would never get done.

The second problem is that the Seti CUDA application isn't using all of the stream processors in Fermi cards either, as it doesn't know about most of them. This can amount in further errors.

A beta test with the newest science application is underway at Seti Beta. But that application isn't available yet on this project. See this thread in Number Crunching for more information.

Windows Vista's and Windows 7's Aero desktop takes up a lot of GPU memory that you would like to use for other things. Nice as it may be, if you want to run tasks as fast as possible with as little errors as possible, you turn off all they eye-candy that'll slow down the rendering of your desktop. This isn't just Aero, it's all those "smooth movement" options for all the windows and icons as well. They all take up normal RAM and GPU RAM.

Good info Jord. I didnt read about the 4XX series having that problem.

Thanks for the info. I'll disable GPU crunching for now and wait for the next version of BOINC!

a new version of boinc won't help. it will be a new version of the seti CUDA app. this may take some time since the original app was created by nvidia and it doesn't appear that they are making the same effort for the new Cards

nVIDIA wouldn't cut into one's own meat* if they don't make a new CUDA app for their GTX4xx series GPUs?

Hey, maybe ATI could jump in and make an app for their own GPUs!
