Having issues getting my MSI Z170A Gaming M5 board working with 6 Sapphire RX570 Nitro+ cards.

I've done the following:
PCIE : Auto
4G Decoding : Enabled
Integrated Graphics : IGD

But when it boots it gives a ton of errors on AMDGPU ring tests.
*ERROR amdgpu : ring 3 test failed
*ERROR amdgpu : ring 4 test failed
*ERROR amdgpu : ring 5 test failed
*ERROR amdgpu : ring 6 test failed
*ERROR amdgpu : ring 7 test failed
*ERROR amdgpu : ring 8 test failed
*ERROR amdgpu : ring 9 test failed
It also gives errors after that from powerplay saying "failed to send message"

After using Auto, Tried with GEN1, then GEN2 and have the same problems.

(Also, the board has 7 slots and I'm using the first 6 from left to right... should I be using different ones for just 6 GPUs?)

Thanks.

UPDATE : Works with 1 GPU. Going to diagnose slots / risers / cards to try and find the issue.

UPDATE2 : Went through each GPU and RISER... looks like one GPU is bad and is causing the errors. Too bad. Looks like the settings were all correct though. Kept the post for others.

I am having same issue with same board , I can only get 2 running at the same time. But I have another rig with 7 cards running just fine with the same mobo.

I use this board and here's what I did to get it working:
1) Force internal graphics
2) update BIOS to latest
3) make sure mining mode is on
4) set PCIEs to Gen 1
5) This board can be set to boot in Windows. Make sure you aren't doing this in the OS settings.
6) enable 4G encode (I actually couldn't even find this option but everyone says it's important so I'm throwing it in)
7) someone somewhere mentioned increasing PCI Latency timer from 32 -> 64. But I didn't do this either.

If you've done this with no results, test your ram and cpu. Maybe even swap cpus with a working rig, if compatible.

Well I initially followed another user's settings (the same one Tytanick keeps posting) for 6 gpus which was basically just update bios, enable 4g, and use integrated graphics. That works... in general. My problem doesn't seem to be an issue with booting 6 cards, but one specific card. I really think that the problem was that I have a bad card. Whenever that card is plugged in is when I get the errors, and not just when I plug it in as the 6th card. If I use this card with 2 others, I get those ring errors. If I don't use it, I can use 5 cards with no errors. I mean, I can play with some other settings, just saying what I have tested.
