This is bittersweet. I was fascinated with this project from the beginning and crunched on and off for the past few years. I'm glad to see that Boinc was developed so other researchers could utilize what S@H started. As much as I would like to continue to help with this project, I would rather see the back end produce a result than to crunch and not have an answer at all.

Thanks to all those that have helped with questions I have had about how the different applications worked or computer questions in general. I feel I have learned a lot about computing in the past few years when I have stepped away from it for so long.

I know a lot of people are bummed, but I hope that doesn't stop your quest for knowledge. I will continue to crunch for other projects on Boinc (Einstein & MW for now, perhaps another later) with all my rigs, and I hope others do too.

My guess is that the card was not over-stressed. The reason I think that is because there are other "special sauces" of seti you can run that stress the GPU more than the stock application. That is to say, it completes the same task in less time.

I agree with Richard, you just happened to have been sent a bad card. I've been running a 1660 Ti for several months now 24/7 with no issues. I would just RMA the card.

A task is a task is a task . . . . . they are all the same for MB. All that changes is the application used to crunch them.
I figured, thanks for confirming.

Sounds like it is either thermally throttling dropping down in frequency to cool itself off or as Grant suggests, it is not getting enough cpu support to keep the card constantly fed with data and allow the card to boost to its normal operating clocks.
I know the APU is properly cooled, at most it reaches 65 deg C. The latter seems more likely, but I'm confused why.

I wasn't keeping an eye on this computer for a month and I jumped into Lunatics, so perhaps something had changed in my normal performance. I'm going to go back to the stock apps for awhile to verify that it was running as before (that is, 1 task running an AMD GPU full bore, 1 NV task full bore, + 2 CPU tasks) before jumping back in.

As for the Lunatics post about APUs...very interesting, but it refers to older architecture. I'm guessing Zen tech is better, so I don't know how much this applies to my current situation. I did run an experiment awhile back, and found that running all cores provided more credit than to disable one of the four cores. My computer has changed since then with the addition of the 1660 Ti. Its probably worth revisiting, but I'm not sure when I'll have the time to collect the data.

Task 8546373524 took about 75 minutes to complete, way more than I'm used to. I'm haven't been keeping a close eye, so I'm not sure which anonymous application crunched this task. Assuming this is a problem with the application and not my computer, I have a couple of questions/observations:

1. Does the driver version matter for the APU? I would assume not, but for what its worth, I am using the latest driver (Radeon 20.2.1).
2. My APU clock speed stays pretty low most of the time. HWinfo and Task Manager show it around idle (400 MHz) most of the time, with peak clock speed (1100 MHz) only on occasion. That isn't how it typically has run in the past, but I have seen this once before. I don't recall if the problem solved itself, or if I did something different.

Edit - #3 - (I knew I forgot one!): Richard, I know you mentioned that the new applications we run via the installer will still use the same tasks. I believe all of these ATI/AMD tasks are still from the "stock download". It probably doesn't matter but I thought I would mention it anyway.

Yes, I have heard of that many times here, but I have always had all four cores running and the APU tasks would complete in that amount of time. I suppose the one core supporting the 1660 Ti could be loaded a bit more, but that seems unlikely. I use to run the system with three CPU tasks and one GPU (APU) tasks. I would guess a CPU task would load the core the same, if not more, than a GPU.

If I drop a core, I don't think my performance is significantly greater on the GPU, so I think I am worse off in that situation than running the stock applications.

Thank you, Grant, I'll keep with the SOG application. I'm running across another problem, though, this time with my Ryzen 3 2200G APU (GPU portion). When tasks used to take 45-60 minutes, I find they are crunching still after a few hours. I'm not sure if the Lunatics application is not suited for the APU, or if I did something wrong. I have been switching between the HD5_r3584 and the APU_r3584 applications, and I think I'm getting the same results with both. I have been a bit busy, so I haven't been able to babysit this as much as I would like to.

Any advice? I have some command line tweaks that I have run on the stock application before, but that doesn't seem to be affecting things as far as I can tell.

Thank you for setting this up, Richard, it was easy to install. I am confused, though, and it may be that I am assuming something. I thought the Lunatics installer was supposed to install the application for Nvidia GPUs to run the CUDA version of the MB application? My 1660 Ti appears to be running OpenCL, and my completion times don't appear any better (maybe worse, but I haven't had a chance to tweak the command line yet). I know the real good stuff is available for Linux, but I thought there was at least something better than stock available for Windows 10. I would dig through all the old posts on the board right now, but unfortunately I don't have that time.

Additionally, as some constructive criticism, I would recommend updating the hardware listed in which application to choose. For example, for "ATI" GPUs, the MB8_win_x86_SSE2_OpenCL_ATi_HD5_r3584 application was automatically selected for my Vega 8 APU. First, I assume this was automatically selected because the program detected my GPU? Second, it says this application is for HD5xxx and above. I apologize, but I haven't been paying close attention to hardware until a little over a year ago, so I have no frame of reference what an HD5xxx series GPU is. Perhaps the installer needs to list more modern cards, such as the RX400, RX500, and RX5000 series GPUs? Same story for Nvidia as well.

I was the one who made that PSA post on reddit. I knew it got good visibility on the AMD sub, but I had no idea that people wrote articles about it.
That is good that the warning spread, but once beta proves it works, articles need to be posted to say it gas been fixed!

Post:
To clarify, the task was compared to the same task ran by a different user, and you both have different results. A third task has been generated and sent to another user to see who is correct. This is normal, nothing to worry about unless you have a significant amount of tasks reporting back as invalid.

Glad to hear the fundraiser has met its goal! I would like to donate as well. However, isn't UC Berkeley charged a small fee with a credit card payment? I know I sound older than I am, but I'd be happy to mail a check to make the donation stretch a little more.

Also, according to PCPartpicker, Newegg has the drives for $407/ea, but you're only limited to 20.
Edit: Also has free shipping!

There is one - I wrote it!

https://github.com/BOINC/boinc/pull/3183

Mind you, it was developed for and tested on my INTEL Intel(R) UHD Graphics 620 host.
Oof, and I even posted in the original thread all those months ago, that's embarassing. This is what happens when I get distracted with other things. Sorry about that, Richard!

Post:
I enabled the Intel GPU processing in my SETI settings and installed the latest Intel 630 drivers. BOINC still didn't recognize the GPU.

But, I am running BOINC 7.14.2 and I saw from the BOINC download page that 7.16 is a beta version. Seeing that I'm still looking for operational stability with my CPU clocks and voltages I don't feel comfortable installing this beta version. It adds another variable into my equation for now.

Maybe instead of using the Intel GPU for number crunching I ought to connect my 2nd monitor it. Would that free up my 1080 card a bit for number crunch vs. pixel pushing?

I would leave my main monitor connected to the 1080 card for when I am using the computer for content creation and light gaming.
What does your Boinc event log say about the 630? I'm wondering if it is recognized there.

I don't think the 7.16.3 beta would enable the 630. I'm pretty there haven't been any developments from 7.14.2 to 7.16.3 on that front. Good call on keeping variables to a minimum, though!

Hard to tell with the information provided. I assume this happens when boinc loads and Seti is running? Do you know if thermals are okay in the computer?

Besides that, I would also suggest downloading bluescreenview, which will give you a log of what error code triggered the bsod. Let us know what code appears and we may be able to help.

And the same is true for SETI. Our actual scientific code has been evolving since 1999, and most of the pips have been squeezed out of it already. There is accepted, proven, code already in existence. The toughest part for a new programmer will probably be to learn their way around the somewhat complex spaghetti of previous code, and decide what to keep and what to throw away. It will be especially important to keep the 'accuracy' components which have been improved over the years: unless any new application adheres to the same standards of accuracy as the existing apps, the results will not validate and the app will be discarded.
I think one of the harder parts will be learning how to dig through the code. I minored in CS, and I put comments everywhere, basically explaining every step along the way. I've casually browsed through the BOINC code (I know, its different than Seti), and I haven't been able to find many comments in the code, if at all. I'm also having a hard time seeing how some of the code is divided in different directories, and what that all means. Now, I've only browsed briefly, so I could be missing something. I'm also willing to concede that my CS knowledge is minimal, and since I haven't practiced in fifteen years, I may not have the foggiest idea what I am doing.

The point that I'm leading to is if the reality is that the code isn't well documented, perhaps that is the first step? I could see that being a benefit for both new and experienced coders.
