solution:
 disabled IOMMU in bios.

and when I tried to read from the drives I arrived at problem 2:
 Uhhuh. NMI received for unknown reason 31 on CPU
 Dazed and confused, but trying to continue
 Do you have a strange power saving mode enabled?

solution:
 disabled AMD Cool&Quiet and Global C-State Control in bios.

I didn't have these issues with Intel Core i5-2500K and MSI H67MA-E45 motherboard.
The raid card really doesn't like Seagate IronWolf 8TB drives, however.
