Also, suspect corruption in the operating system or drivers. For an example, see this thread: Continual computing errors | |

I'll give a try making a clean install of nVidia drivers, and if doesn't work either, I'll install a fresh XP. | |

You may be fighting the same stability problems I was with my pair of GTX 260s. The fans weren't speeding up as the card started running CUDA full tilt, so the card would soon overheat and become unstable, causing driver errors, BSODs, and failing the work units in the process. | |

This is to both dJ3781 and pharring. Do you both have at least a 700 watt power supply? Nvidia recommends a 680w PS for the geforce 295, and 500w for a single 260, with about 183w for the card, so a second one would be just shy of 700w. If you aren't deviling enough power to the card, then yes, you will have computation errors, with a sporadic few working fine. | |

I have a Corsair CMPSU-750TX (750W) which have been proven to be able to deliver more than 750W. So I guess that it's enough to make my GTX295 run at 100% for a while :( | |

So I guess that it's enough to make my GTX295 run at 100% for a while :( I would be suspicious of that statement. It can deliver the power and not melt down this is true, but, I think something is clearly saying that it is not happy. Are you using direct connections from the PSU to the card? Or using the work around plugs? Some PSUs though rated as having enough power may not actually have enough power (amperage) on the critical "rails" to support the draw ... Do you have another PSU of equal or greater power? Another PSU of any size? You might want to try running the Disk drive, DVD and fans off a second PSU and the MB and GPU off the other ... a noisy component could also be the culprit ... | |

Well, 750W seems far enough for a single video card oO | |

Well, 750W seems far enough for a single video card oO Yes it does. But 750 watts of what? And I ran 2 cards on a 780W PSU ... but it was also a higher end version and I since changed it out for a 1K ... looking at the wall draw I am only pulling 600W so either should be adequate. But the key words are "should be" ... If the card needs 200 W on the 12 volt rail and there is only one 12 volt rail and it is only capable of providing 190 watts, you are ten watts low... giving rise to potential problems. Secondly, if there is a component that is generating a lot of noise on the supply line that can disrupt the GPU, which is why I asked if the GPU was being directly fed from the PSU or you were using the disk drive power lines through the adapter provided. The notes in all my Nvidia cards strongly suggest that you not use that except as an interim solution. I am not saying that these are the case, I am simply suggesting that there is still the possibility that it is the PSU. The other possibilities are the GPU itself or the MB ... both harder to test ... Anyway, just trying to make suggestions so you can consider things to try ... | |

I'm sorry, I just went through your post a bit too fast... | |

Perhaps that is best. What I have experienced is smooth sailing with the first GTX 280 card, then with the GTX 295 I got later. And hopefully wednesday I will get another good card too ... | |

Anyway, thank you for your help, even when I got kinda rudish. | |

My power supply is an Enermax Revolution 85+ | |
