So I recently upgraded from a GeForce GTX 560 Ti to a GTX 660 Ti, and ever since, all SETI@Home GPU tasks have failed with a computation error. I let it sit since August 24 with the 'No new tasks' option so I could finish the leftover CPDN tasks, and uninstalled BOINC, deleted the ProgramData\Boinc folder (I thought it was perhaps assuming I still had a 560 Ti), reinstalled, and today, the first cuda_fermi task failed, again. Other GPU applications, like those from GPUGRID and Milkyway@Home work perfectly on the new GPU, even when I hadn't reset everything by uninstalling and deleting program data. Any suggestions? P.S. See this task, for example. |

It is a known issue with the newer drivers and the stock app. Currently the only solution is to install the optimized apps as they do not have that problem. http://lunatics.kwsn.net/index.php?module=Downloads;sa=dlview;id=330 You will have to keep an eye on the forums here as we will be releasing an updated installer once multibeam v7 is released. |

It is a known issue with the newer drivers and the stock app. Is it only with Kepler GPUs though? The GTX 560 Ti worked fine even with 3xx series drivers. |

Yes it is, it was first discovered with a GTX-680. This thread... http://setiathome.berkeley.edu/forum_thread.php?id=68588 |
