I have two GTX 260's. One of them finishes tasks in about three minutes while the other takes about ten minutes. The results are always invalid or inconclusive for the one that finishes quickly. I have tried different versions of BOINC, drivers, even operating systems to no avail. Here's a look at the stderr_txt: Name 01fe09ab.888.10297.11.8.101_0 Workunit 437519149 Created 28 Apr 2009 4:44:24 UTC Sent 28 Apr 2009 7:20:55 UTC Received 28 Apr 2009 11:53:53 UTC Server state Over Outcome Success Client state Done Exit status 0 (0x0) Computer ID 4899468 Report deadline 21 May 2009 2:58:06 UTC CPU time 56.07813 stderr out <core_client_version>6.6.20</core_client_version> <![CDATA[ <stderr_txt> setiathome_CUDA: Found 2 CUDA device(s): Device 1 : GeForce GTX 260 totalGlobalMem = 939524096 sharedMemPerBlock = 16384 regsPerBlock = 16384 warpSize = 32 memPitch = 262144 maxThreadsPerBlock = 512 clockRate = 1408000 totalConstMem = 65536 major = 1 minor = 3 textureAlignment = 256 deviceOverlap = 0 multiProcessorCount = 27 Device 2 : GeForce GTX 260 totalGlobalMem = 939524096 sharedMemPerBlock = 16384 regsPerBlock = 16384 warpSize = 32 memPitch = 262144 maxThreadsPerBlock = 512 clockRate = 1408000 totalConstMem = 65536 major = 1 minor = 3 textureAlignment = 256 deviceOverlap = 0 multiProcessorCount = 27 setiathome_CUDA: CUDA Device 1 specified, checking...

Is this card bad or is something wrong with my setup? Why just one card? |

This appears to be happening because the results being returned by your card, give different results to other computers running the same Work Unit. |

Are you OCing? If so try reducing it... If its factory OC'ed then again try reducing it. Also check the temps... GPU's are more likely to produce errors at over 80c.

Tried turning the clocks down ridiculously low, core, shader and memory. Problem still manifests no matter what the settings. Replaced thermal tape on heatsinks with Artic Silver paste, set fan speed to 100 percent, runs at 50C. I'm at a loss. I have noticed that while crunching, it runs slightly slower than my other card when observing the percentage complete. I'm guessing it must be a dud as far as CUDA is concerned. |

Well I'd suggest RMAing it. If its having problems with cuda it will most likely have problems with other things as well. Bob Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957 Or Good Shop? http://www.goodshop.com/?charityid=888957 |
