Since I never have used a mainboard with built-in ATI CrossFireX/Hybrid CrossFireX technology, I cannot help you.
Furthermore your last post has nothing to do with the topic of this thread (your modded BIOS obviously supports booting off an NVMe SSD).
Thanks for the answer, Fernando. I realized that I had written to the wrong discussion. It’s just that this topic discusses the ga 890gpa ud3h rev2 motherboard. And I thought it would be better to ask this question here. I also thought that you were still sitting here under the nickname Dagal, and he described a similar problem with this GIGABYTE GA-EP45-DS3P motherboard. But apparently I was wrong. I apologize for my actions.
