Currently i am trying to build a rig with GA-Z270X-UD3 using 6 vega 64 cards and seems that its very unstable, sometimes it recognizes all sometimes it is not. Sometimes even freezes. I dont know where exactly the problem is and what config to make to the bios in order to make it stable. Can i get any advise on that if someone had similar configuration and issues?
1. M.I.T > Miscellaneous Settings > Max Link Speed > Gen 2
2. BIOS > Windows 8/10 Features > Windows 8/10 or Windows 8/10(WHQL)
Storage Boot Option Control > Legacy or UEFI
Other PCI devices > UEFI
3. Peripherals > Initial Display Output > PCIE-1
4. You must use one video card in pcie-x16 to display and install VGA Driver
5. plugin one video card in pcie-slot, add to another 5x video card
The motherboard only can use this to upto 6x VGA card
