Are you sure Boinc is in the right order? I see it give a random order compared to say MSI Afterburner. I had a machine with 6 cards in it, and Boinc's order compared to MSI was something like 3, 5, 1, 2, 0, 4. I assumed it was physical connection order vs. driver loading order. Although Folding@Home is different again. Very annoying when trying to allocate cards or work out which is overheating.

Yes in my case with "only" two GPU BOINC has the right order. The GPU where the boot screen appears is GPU0 and the other (dark) one is GPU1. The same order as the BIOS allocates the screens.

I wonder why it's called that? Git is a rude word.

According to the wikipedia page, because the developer named it after himself, like with Linux.

I don't understand what you mean. I wanted to run the same task on both GPUs at once. If the dodgy one gives a different result, there's something up.

This has never been allowed in any other Boinc Project so far, one task per gpu each running it's own task. It's not like gaming where you can double, triple whatever up on the gpu's to make the game perform better.

Unless you are talking about testing, then yes they often run the same task on each gpu, getting zero credits of course, to test the task on multiple gpu's.

Thank you for this.

I saw the notice in the BOINC client this evening, added a second Nvidia card to a Windows 10 box, updated the cc_config and it all works perfectly.

This could be a severe problem if there's "valid" tasks coming back which aren't. If this was happening before this update, on any machines with more than one card, can you track down suspect results and re-run them?

The result was good.

The 7 minutes I said was from Boinc, which seems to race ahead with the % complete. In 15 minutes according to stderr.txt, it will be complete. We'll see if it validates. Or perhaps you can run that same task on a known good card of your own. I'd hate to think it's giving tasks back which validate but are wrong.

I dont have a good card. A standalone test is the best option to test both cards and track down the issue.

Can you make them both run the same task?

yes but not recommended. The GPU use 99% and CPU is nearly unused. Only a test can help.

Not working in Windows 11 with two of AMD Radeon R9 280X cards (old things - 3GB, OpenCL 1.2). Both run and show progress in Boinc, but the second one shows 0% usage and generates no heat.

I assume the required version you speak of is the version of SRBase, which Boinc updates itself? I have 0.28 against the running tasks.

Can you post the stderr.txt of the 2nd card?
