	Although your GT640 is indeed a Fermi card (compute capability 2.1), have you tried setting the CUDA_GRID_SIZE_COMPAT environment variable described for Kepler cards in the driver problems thread? I doubt that it will cure it, but it won't do any harm. Edit - what's that major = 3 minor = 0 doing in there? Looks like CC 3.0 - in which case the environment variable will help, and NVidia's documentation is wrong. What make/model is that GT640? 2nd. edit - according to wikipedia, there are four different versions of the GT 640 - three of them are Keplers, and only one is a Fermi. So http://www.nvidia.co.uk/object/cuda_gpus_uk.html only has a 25% chance of being right. Gnash.

	This might be a shot in the dark, but people have been having problems with BOINC 7.0.28. I would suggest trying BOINC 7.0.25 ____________

	It's a Dell XPS 8500 with a NVIDIA GT640 1gb GDDR5. As to what specific model number, I do not know. ____________

	No Joy on 7.0.56 I'm not surprised, as it's an application problem, not a Boinc problem, see Richard's advice. Claggy

	Due tot he error rate on your computer can I request that you either stop it crunching S@H, or turn it off: http://setiathome.berkeley.edu/results.php?hostid=6942032 ____________ Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe?

	I'm still getting errors from time to time with my 560ti's also but no where nearly as bad as before, for me since I have a sli setup if I see fermi's finishing within 1 minute I will do a temp fix by turning on sli in Nvidia Control panel, when I do that it gives me a window of time where all the fermi's that run finish good, once the error comes back i turn off sli and again that fix's the issue tell it comes back again. I noticed the latest version of boinc helped also. I think the latest drivers of nvidia has a update for cuda also.

	Here is the GPU-Z info You have GK chip. K stands for Kepler. So you have GT640 with Kepler chip, you need the software for cuda_kepler. Richard, I looked at the thread you linked earlier, it is dated October 2012. Is there a solution for Kepler cards now? ____________

	CUDA_GRID_SIZE_COMPAT Value = 1 Because you wrote it like that, Did you put in CUDA_GRID_SIZE_COMPAT Value = 1 Or CUDA_GRID_SIZE_COMPAT 1 (with the 1 being in the value column) Claggy

Is there a solution for Kepler cards now? The solutions are: a) Use an optimised Cuda application, where available. b) Downgrade to the 301.42 driver - only possible on GTX 670/680/690 cards, not on newer releases like the 650/660 or their Ti variants. c) Set an environment variable, as shown below. d) wait for Setiahome v7 to arrive, it'll use the app from a) Claggy
