" rel="nofollow - Hello!

I have an Asrock Z270 Taichi motherboard.

When I plug in 2 graphics cards, it works fine. When I plug in the third graphics card, it automatically enters BIOS and freezes. Also I have A6 error, which means it is smth related to IDE or SATA. Why it appears only after I plug in the 3rd GPU?

I have Radeon Pro Duo 32 GB GPU, 1200 w power supply, latest bios version, win 10 - 64

" rel="nofollow - I have an update. I've disabled the intel virtualization technology and hd audio. I've changed the top of lower usable Dram from dynamic to 1gb, and PCIE link speed from auto to gen3 for all pcie.

After that I have managed to connect 3 graphics cards.

However, when I put the 4th one (the last graphics card I have) the computer doesn't switch on. I have just a black screen and a b2 code on the motherboard. How can I solve this?
