What I'd like to know is why Rob's 5700XT reporting the invalid tasks. The counts are way off from the canonical result. Is there still a problem? Or is Rob overclocking the card too far causing the invalids? Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Or maybe temp related. If it’s an early reference design, they tended to run hot from what I remember of the early reviews. He’s still producing mostly valid results. So that’s good. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

Got two invalids on RX 5700 with 8.24 beta, in case it is relevant The first result is missing a pulse, the second one has several too many. That's not nearly as bad as what was happening before. Pulse finding is one of the more stressful portions of the code. @SETIEric@qoto.org (Mastodon) |

Thanks, Eric! Appreciate the explanation. Glad to hear 🙂 |

It would appear it's now time to follow up with the people who were producing bad results and let them know that the solution is at hand. As far as I know as 8.24 has gone to main, it will update automatically, and fixed drivers can be had at https://www.amd.com/en/support I don't think there's anything else I need to pass on, but please advise if otherwise. I'll give it a while and then start sending messages. |

You might state that they have to use the Beta drivers. The Windows WHQL drivers are too old. [Edit] Also maybe a friendly tip that the use of DDU is advised also when installing the new drivers.

Long thread, trying to catch up. Sorry if repeat something. I just got my AMD GPU working again on SETI after many years MIA, also related to driver issues on OSS Linux. I came back to the forums to report and found this thread. 1) Is there are summary of this issue somewhere? 2) This was a problem with 5700 XT, exclusively, is that correct? No other cards are affected? 3) It affects all platforms, right? Linux too? |

2) This was a problem with 5700 XT, exclusively, is that correct? No other cards are affected?It affected all the 5000 series cards. There is now a new application, which when used with the latest driver release, appears to have fixed the problem. But both the new application and the new driver are required, just one or the other won't do it. Grant Darwin NT |

Answer to 2) It affected all RX5xxx GPUs. To get an overview of the situation it is best to look for posts by Eric Korpela (https://setiathome.berkeley.edu/show_user.php?userid=24735) He's been working on a solution, which appears to be in two parts, first a new version of the drives, and second a new version of the application (8.24) The last "official" news was that the new application was in Beta test https://setiathome.berkeley.edu/forum_thread.php?id=84508&postid=2027496 but there is no confirmation that the application has been released here on main yet. Tthere were some server problems just after Eric posted that so it is quite possible that he didn't have time to do all the things required to release an application formally on the main site.

1. A driver/software issue causing incorrect compute results to be produced from AMD Navi cards. These incorrect results would occasionally get compared to another Navi GPU, and be validated, and the correct result was discarded. 2. 5700 and 5700XT for sure. probably all Navi cards. but I'm not sure if anyone has identified any of the newer lower end cards yet. 3. Unsure, but probably. I don't think we found any/many people running these cards on SETI in Linux. almost all of them were on Windows. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

And it does effect Linux as well with the RX5xxx series. Cheers. |

One thing I'm not clear about is, does version 8.24 depend on having the "correct" driver version. I've just had a look at some of my recent "valid" results, and one user with an AMD GPU is suffering from errors and is using version 8.24. https://setiathome.berkeley.edu/show_host_detail.php?hostid=8393099 One of the error tasks stderr (first few lines, it gets very repetitive....)

I believe it does indeed require the new driver as well. It’ll take some time, but eventually most people will update their drivers. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

One thing I'm not clear about is, does version 8.24 depend on having the "correct" driver version.That was my understanding. AMD released a driver that specifically addressed the issue, explicitly staying Seti@Home. And Eric posted that it required the application to be recompiled with the changed compiler flag.

I still can't see if the (luckily only) nine tasks I ran on my RX 5700 XT have validated, because of the trouble with the whole back-end. |
