I did all steps posted by @Vann still unusable Windows. I changed partition type from mbr to gtp reinstalled os 10 uefi with 1 rx580 in slot. turned off secure boot & csm. DDU in safe mode then installed adrenalin driver with all 12 gpu inserted. its almost impossible to use windows. i have to wait like 10 minutes to login windows. mouse is lagging. After waiting like half hour to get in, claymore error "miner didnt start for 5 minutes, restarting...". I also tried smos which is great but i dont want to use ethernet cable so i need windows.
Any suggestion ? Could it be motherboard ? Asus optimisation software shows 12 available gpu, everything is ok with raisers, except that windows is lagging.

You didn't mention which PSU youve currently got and how did you manage the power management.

Have you tried what I suggested before?
