Many tasks error out due to detecting the GPU as Device Emulation (CPU) Driver 180.48 Vista 64 Tasks that work detect it as Device 1 : GeForce GTX 260 And complete tasks in about 63 sec. Here is one of the errors. http://setiathome.berkeley.edu/result.php?resultid=1099202572 Task ID 1099202572 Name 15no08ad.17153.14387.11.8.97_1 Workunit 384496005 Created 23 Dec 2008 12:15:31 UTC Sent 23 Dec 2008 12:15:56 UTC Received 23 Dec 2008 12:28:39 UTC Server state Over Outcome Client error Client state Compute error Exit status 1 (0x1) Computer ID 4724325 Report deadline 10 Jan 2009 10:52:54 UTC CPU time 4.383628 stderr out <core_client_version>6.4.5</core_client_version> <![CDATA[ <message> Incorrect function.

Are you sure BOINC is not installed as a service (Protected application execution)? If BOINC is installed as a service on Vista it can't recognize the coprocessor... |

When he starts up Boinc it should say if it's benn recognized in the Boinc message window log if it's installed correctly. Edit Seems to indicate here that it is. |

Looks like it starts up fine.

Switched from Driver 180.48 to 180.84 and it runs for a little while then crashes the in the video driver. Not temp related, I watched crashes happen with GPU temps from 38 ( just started ) to 55c ( after a task or 2 completed ) Since I see that this is getting looked at, I'll hold off on the Cuda for now until I see another update. |
