I´m working on this behavior for a couple of month now.
Since you also have errors on the CPU as well and MB on GPU it`s hard to say actually.

You can try this comand line.

-unroll 16 -oclFFT_plan 256 16 256 -tune 1 64 4 1 -tune 2 64 4 1 -ffa_block 5660 -ffa_block_fetch 2830 -cpu_lock_fixed_cpu 6 -hp

It fixed it for me on my 380.

I recently installed an AMD RX 580 GPU and just noticed that Astropulse results are invalid. 2 bad results are ID 7584720987 and 7584330887. Was hoping for an answer/fix in this thread, but I'm not really sure I understand what the resolution to the problem is. Any suggestions?

Andivb, to the best of my knowledge, the problem I brought up in this thread is identified and being worked on, but a fix has not been implemented yet. It is a fix that needs to be completed on the server software, not for the individual user. This problem was also discussed in another thread located here.

With that said, and with little expertise that I have (actually, no expertise), I don't think the problem you are having with your GPU is the same problem that I have been experiencing. I see that you have task 7584720987 as completed and valid. That is further than I have been able to get with my APU for any GPU task. You do have a few tasks that are invalid, which to my understanding is different than a computation error.

APU is a different story.
