I have received the following updates to my NVIDIA bug 1574543: Richard, I received exactly same message from exactly same named person. Just FYI. But, yep, best of luck... |

I checked the message boards and I, obviously, fall into the pre-Fermi category, but no combination of older or newer drivers allows a CUDA data file to be used for any more than about 15 seconds, then resets to 0, starts over, and eventually reports "Computational Error". I just did an uninstall and a re-install of BOINC and a disconnect and re-connect for the SETI project. I realize I need newer hardware to be able to do newer things. The only reason I had a video card with a GPU was to use it for SETI. I don't do gaming, so old is not an issue for that. I'm just trying to figure out if my system is the reason the GPU stopped working of if something changed in BOING that rendered my GPU useless. |

Can you do the Remove Seti and add Seti again, I'd have expected to see a lot of abandoned work, But there is none, try and complete as many CPU tasks as possible before you do it. (Set NNT) The scheduler did once send you Cuda32, Cuda42 and Cuda50 work, and have high Max tasks per day for all three, But insists in only sending Cuda22 and Cuda23 work now, strange. Claggy |

I just did an uninstall and a re-install of BOINC and a disconnect and re-connect for the SETI project. Removed and re-added Seti. Also made sure the newer PhysX package was removed and clean-installed NVIDIA driver 266.58 (as recommended in an earlier message in this thread). A CUDA23 file started up and had been running for 5 minutes, now, with no problems noted. Download a whole bunch more CUDA23 files after that. A "contaminated" file may have been the issue. If the current CUDA23 file successfully finishes (in about 2 hours) I will know, I guess. As for not getting any CUDA32, CUDA42, or CUDA50 work, I remember getting those in the past, but can't remember when they stopped. Thank You for your help. Bruce Parker Dumfries, VA |

About terminology: The only reason I had a video card with a GPU was to use it for SETI. Every videocard and videochip out there has or is a GPU. This abbreviation stands for graphics processing unit and is used to render anything on the monitor. Without a GPU, no images on the screen, not 2D and not 3D. So a GPU is not something awfully new. The awfully new thing about these is that since a couple of years they've become so powerful that they can be used for doing calculations or their own. This in general is called a GPGPU, or general purpose computing on graphics processing units. |

Everything seems to be back running normally. I have processed a couple of CUDA23 work units with no apparent issues. Bruce |

Just a note it, looking at my results again, it was both cuda22 and cuda23 that showed as having an 'error while computing'. I see now in my tasks I have a cuda 22 at about 60% done and I forced a cuda 23 which is also now at about 60%. I assume this means all is well now. -Matt |

i have recently upgraded my pc to AMD a8-5600k with radeon hd graphic 3.60Ghz and also a Nvidia geforce 210 card. my concern is how do i know if my GPU is working and calculating my Seti WU's? As i have noticed that i have dropped from 4 WU at one time to three and wonder if this is the reason? M MM |

I have an update, and it's good news I believe, in regards to my NVIDIA bug 1574543: https://developer.nvidia.com/nvbugs/cuda/edit/1574543 5 November 2014 9:32 pm -- Kevin Kang 12 November 2014 11:28 am -- JacobKlein [NEW] 14 November 2014 1:21 am -- Kevin Kang |

[NEW] This certainly concurs with the way I interpreted the existing Cuda documentation (not in an pure OpenCL context). We're at an inevitable juncture where upcoming OSes will require hardware features only available in Fermi+, mainly 64 bit addressing, and the emulations having taken place to bring the older gens along so far have become unwieldly (making the older cards crunch slower with each driver iteration). The line makes practical sense for nVidia. It's just really unfortunate that the timing of these moves was near Maxwell release, resulting in the usual driver maturation problems converging with unrelated major changes. Could definitely have been done cleaner IMO, though I suspect there'll be some more growing pains yet. "Living by the wisdom of computer science doesn't sound so bad after all.

It was known, by me, since March, that R340 would be the "end of the line" for pre-Fermi GPUs, per http://nvidia.custhelp.com/app/answers/detail/a_id/3473. I chatted with an NVIDIA agent, then, and confirmed that pre-Fermi GPUs would not be recognized by R343+ drivers. So, that prompted me to pull my GTS 240 GPUs out of my main rig, several months ago. It was NOT known to me, that the R343 drivers running on my laptop's FX 3800M GPU... were corrupting BOINC data. I am happy that it seems NVIDIA will honor their R340 support to fix the problem for the OpenCL SDK examples that I proved were failing. And I'm crossing my fingers that this also resolves the R340 data integrity issues that BOINC OpenCl applications are having. I feel pretty confident that it will! Regards, Jacob |

I have done all that is mentioned in this board to get my GPU to start working seti WU's but still no joy. Is there something I have missed or not done to get my GPU to start working thru the seti WU's. The only reason i upgraded my Nvidiu card was so I could do more seti WU's. Can anyone help me to get my system working at it best for seti WU's. |

Apart from there being very few tasks around just now for everyone you are still running the wrong version of the Nvidia drivers - you should be using an older set, 337.88 appears to be about as new as you can go - which can be downloaded from the Nvidia website by looking for the older drivers. Do a an advanced/clean installation otherwise the drivers won't be properly replaced. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Can anyone help me to get my system working at it best for seti WU's. I'm starting to think that the project has limited Pre-Fermi GPUs to the MBv7 Cuda23 and Cuda22 apps, and put in a Max driver limit in too, Inspite of the MBv7 CUDA apps NOT being effected by the 340.52 OpenCL Pre-Fermi driver Bug. The way round the driver limit is to install the Lunatics apps, But just install the Cuda23 MBv7 GPU app, DON'T install the NV OpenCL AP GPU app, it won't work properly on Pre-Fermi GPUs (Edit) on 340.xx drivers.

The OpenCL AP app is fine, provided you haven't installed the 340.xx drivers, or if you have, you uninstall them again first, and revert to 337.xx or earlier. |

Just a little more clarification, since 341.05 was released as an R340 driver. R340 drivers, like 340.xx and 341.xx, aren't *yet* working right for all OpenCL apps... until NVIDIA hopefully fixes things for these R340 drivers. I still have hope! :) |
