Just a little more clarification, since 341.05 was released as an R340 driver. I wouldn't hold your breath waiting for Nvidia to fix their latest drivers for old hardware as that old hardware is now obsolete in their eyes. Cheers. |

They've indicated that they will fix it, and R340 for pre-Fermi is indeed under bugfix support until April 2016. |

Just a little more clarification, since 341.05 was released as an R340 driver. In the case of the (current) Lunatics app, even a fixed driver won't work, because the application itself has been hard-coded to refuse to run under drivers in the suspect range. Once we have a working driver from NVidia (if?), I'll try to persuade Raistmer to re-release an app which merely notches out the proven bad drivers, and re-allows processing on the far side. If it passes testing, then we can refresh the installer yet again. |

After following @Wiggo's advise and installing 266.58 on both the 8600gs and fx 1800m machines I was getting CUDA units for some weeks then I noticed a work drop off and the red message to upgrade to newer drivers to make use of the GPU. (I'm using BOINC 7.2.42 on one machine and 7.4.26 on the other to keep those variables different.) My memory (which is aging and often fallible) says that that didn't stop getting packets before but I went ahead and upgraded to 320.78 on both machines and CUDA units started flowing again. They stopped again last week. 1) Is this because SETI is running out of work or is it another shut off of CUDA units to pre-Fermi cards? 2) Can someone confirm that 266.58 is cut off from work now? |

They stopped again last week. There's very little work being split, at the moment the Server Status page shows all the MBv7 tapes as done. Claggy |

I have a minor update. Still waiting on a fix, though. 5 November 2014 9:32 pm -- Kevin Kang 12 November 2014 11:28 am -- JacobKlein 14 November 2014 1:21 am -- Kevin Kang [NEW] 5 December 2014 8:40 pm -- JacobKlein |

I did warn you not to hold your breath on a fix, but is there any good reason why you can't just use a pre-340.xx driver? Cheers. |

I am using 337.88, so I don't damage the science results. I am also testing each and every NVIDIA driver released for my GPU, against their own OpenCL SDK samples, and keeping the pressure on NVIDIA for a fix, since they vow support until April 2016. I'm not holding my breath. I'm doing my very best to resolve the problem and keep the community informed. I feel like I have very few allies, in this quest. Lighten up. And have a great weekend! Thanks, Jacob |

I feel like I have very few allies, in this quest. You have many sympathizers instead, perhaps :) I already passed that route with own bug reports waiting much longer than 4 weeks. Yours have a possible advantage for mentioning their own examples that fail, that would make situation more intolerable for NV in case they would care. Seems they just don't care. Virtually no updates for OpenCL support given. Perhaps we should be just glad that OpenCL support not completely revoked in new drivers.... |

I don't yet think that they don't care. Rather, I think that it is not yet a priority to them. We will see. |

I don't yet think that they don't care. Rather, I think that it is not yet a priority to them. We will see. I'd tend to agree. Cuda7 early alpha only just ended, then there'd be DirectX12/Win10, Maxwell midrange products, and 'a bazillion' 64 bit Denver Tegra K1 cores for the Google Nexus 9, absorbing dev resources along with silicon, not to mention the blindside by AMD with Mantle low-latency gaming drivers/apis in there to compete with. Yeah, spread pretty thin I'd reckon. Not to say they shouldn't address the problem, or have plenty of resources to address it, though I know I'd have trouble justifying dedication of resources for no immediate return pretty hard to take before a shareholder or board meeting ;) "Living by the wisdom of computer science doesn't sound so bad after all.

I would thing there is a fixed budget for Tesla Driver support and if they don't use it they lose it, so I think work is being done using some sort of priority system. If it is like any other company, sometimes it is a struggle to find a task and charge number to work to. |

I'm sorry if you don't like my replies Jacob (and I don't mean to p*** you off), but even though your GPU was released in 2009 (making it 5yrs old now) it is based on 2008 architecture (making it 6yrs old now and the usual end of support mark) and I've seen these things happen so many times over the last couple of decades I just expect it. The changes between those cores and Fermi (and newer) cores are like chalk and cheese in comparison and that makes the size of the newer drivers better not supporting those older designs, but also cheaper to produce. ;-) Cheers. |

Don't get me wrong, I know the GPU is ancient, and I expect support to be dropped at some point too. But the facts are that support isn't over until April 2016, and there are some serious OpenCL bugs that they introduced in their R340 line of drivers. Now is the time for someone to jump up and complain, before support is over. And the complaint needs to be as clear and straightforward as possible, which I have done, knowing full well that their "motivation to fix" must be quite low. I refuse to let up on the pressure. Not holding my breath, but also not going down without the best fight I can put forth. These old GPUs still have some use in them :) It's the R343 drivers that have dropped support for pre-Fermi GPUs. But the R340 drivers, which will be the "last line before support is entirely dropped", need to be golden... and right now, they're not. Regards, Jacob |

FWIW, totally agree with both points of view here. I would only add that for some time there have been chaotic changes going on, no doubts still to be resolved. So in some cases 'right' answers may not yet exist. "Living by the wisdom of computer science doesn't sound so bad after all.

maybe someone can help me. I have NVidia GeForce 315 ver. 340.52. I don't get any GPU for seti when I ask for WU. It stopped getting WU's about 1 month ago. My setting should be OK. What am I missing? |

What am I missing? You're missing the news which was posted on the front page on 13 November, and also passed on via the 'Notices' tab of your BOINC Manager: SETI@Home: Running out of workunits. But don't worry, that's now been replaced (on 5 December) by SETI@Home: New Data from AO (Arecibo Observatory). There are workunits being processed now, but the pipeline is still (slowly) re-filling, and they are hard to come by. Your computer should resume processing normally by the middle of next week. Having said that, your GeForce 315 is one of the older "Pre-Fermi" graphics cards that this thread is warning about. You should revert back to the previous driver while you're waiting. |

I'm starting to think that the project has limited Pre-Fermi GPUs to the MBv7 Cuda23 and Cuda22 apps, Bump. mrchips has plenty of CPU wu's, and should get MBv7 Cuda Wu's, assuming that there isn't a driver limit put in for the Cuda apps. Claggy |
