I solved the issue.

When you have to constantly restart due to no display. The bios settings in the mobo eventually change without warning. 4G was disabled by the mobo/windows 10 in order to get back into boot.

I re-enabled this and got 6 GPU's working.

I've tried formatting now twice. Both with and without windows 10 support in the BIOS.

Starting to think this is a chipset issue maybe. I'm not getting any display when I have PEG with graphics cards enabled, when I do get a display its because ive hit the restart switch like 4-5 times.


Sent an email to MSI.

The worst thing is that I have 7 of these boards :/

 

Having the same issue with MSI Z270 SLI PLUS. Won't boot up most of the time even with 1 card on PEG.

I've been setting up some rigs using the MSI Z270 SLI PLUS motherboard but it's having serious issues starting up with more than 2 GPU's.

Using Powercolor 570 rx 4gb Hynix x 6
Rig 2 is MSI armor 4GB x 6 - Looks like its having the same issues
I do have experience setting up rigs so I go through the normal motions of trying all the combinations of settings.

- We have new risers, switched out for older version risers which we know are working but that didn't solve it.
- PEG Enabled
- 4G decoding
- PCI Speed- Auto/Gen 1 work, Gen 2 doesnt work, miner would crash.
- Mixed Drivers
- ATI patch
- Latest Bios Flashed
- Windows Updated
- Tried PCI speed latency 92, not working


Sometimes on start up we get 1 out of the three cards with a yellow triangle in device manager. I have got them to miner successfully but not more than 1 card.

I also had major issues using simple miner, it would get stuck on boot up.

Processor: G4400
Mem, Corsair LPX 3000MHZ
SSD: Sandisk 120GB/ 3.0 Sandisk Ultra Flair, both not successful.
PSU - 1000W EVGA GQ.

Getting desperate now as we have equipment for 7 new rigs. I would tip substantially for a working solution.

I'm starting to think it's the motherboard. Although we made a rig last month on this board and it worked, just not with M2 slots.

I have multiple rigs and normally dont have an issue troubleshooting.

But I cannot for the life of me figure out why this new rig still not boot up.

I keep on getting a white screen like this with PEG enabled, with IDG enabled It flashes like this a few times then boots into linux, but I can only get 3 cards maximum recognised.


All powercolor 570 RX, PEG enabled, Auto/Gen 1 settings, 4G enabled.

Z270 SLI plus motherboard.
