I got the board yesterday and can't get more than one to work. Have also tried the latest BIOS and Beta BIOS with 4G decoding etc. but nothing works.

I also made your IOMMU settings, even without success.

Please ask for help:)

thank you

for which board?
I want to get the MSI X370 GAMING PRO CARBON for 4x Vega 56 and possibly 6 pieces later

who can confirm that the board can handle 6 GPUs?

MSI released a new bios to support "above 4g decoding" that may help to recognize more gpus.

Hello,

I had previously written on this thread that I could not get the MSI X370 GAMING PRO CARBON working with more than 1 card, or even 1 card in some situations.
My problems disappeared when I disabled IOMMU in the BIOS. After I disabled the IOMMU in the BIOS, everything worked correctly, no more kernel issues, and I have been running it with 4 cards for a few months now.

NOTE: It is a gaming oriented card, and has a high power-consumption. This makes it less than ideal for mining, but it gets the job done.

What does "it doesn't work" mean? Are you booting Windows or linux? What error do you get?
