OMG thank god I find a recent post with this problem. Same thing is happening to me.

I have a setup with only two cards (I've taken out the rest to narrow down the problem) and I've tried everything but still get the hang on gpu1:

- Swap the cards (between several)
- Change risers
- Change motherboard and cpu (yes, I have several)
- Reinstall drivers
- Use different Claymore versions. I have other rigs running with 9.5 and 9.7 without issues.



My setup is running on Ubuntu server 16.04 and I've tried diferent cards, RX 580s and RX 570s.
Yes, my cards are bios modded, but they work perfectly if set up in other rigs.

Since the only things I haven't changed are the PSU, the ram unit, the ssd and claymore itself, I will likely find a solution soon, but I'm really tired of this sh***t.


Hopefully we'll find a solution together...


PS: Oh, and one thing I didnt mention is that if I disable gpu1, It works fine and totally stable. It's driving me nuts.

What brand and model are your cards? I am pretty suspicious of mines which are powercolor that is causing the issue. You might want to double check the bios mod of the cards that is causing the issue considering both of them are identical and no issue with riser. PSU should be fine since you are only running 2 cards. You might also try to plug your gpu1 into different pci slot on mobo. Those are the checks I can think of for your case.

And yes I am going nuts with this issue. Hoping to come up with solution. Cheers

It's currently happening to me with an Asus RX 580 4GB Dual OC and an Asus ROG Strixx RX 570 4GB.

I have checked the bios mod of the cards, they both work fine on another rig. Could it be that the PSU line for the riser molex might not be providing enough power?? It's one of the last few things that I have to check...

The PSU is a NOX URANOVX 650w I believe. I don't have access to the rig right now. But what bugs me is that if I use -di option and disable gpu1, gpu0 can run for ages, but if I disable gpu0 and try to mine with gpu1 only it hangs just the same, so it's not a power issue. Hence my question about the molex line in the PSU...


Regards.

650w should work with 2 gpus just fine. instead of trying molex cable, sata etc you can just use another entire riser. just swap it with another one and give it a shot. I have been struggling over a week. So my suggestion for you would be to jot down every step to try in correct order and eliminate one by one. Otherwise you suddenly may find it working out of nowhere and wouldnt know why it worked. And if you get similar problem with same rig again, you wouldnt know what to do to fix it. Let me know how it goes. Cheers
