Hello,
I wanted to disable CSM from my BIOS settings to be able to enable "Above 4GB decoding" for video memory, which is basically SAM, but if I disable CSM I completely lose video output until the OS takes over. This also means that I can't see the BIOS configuration anymore and have to use the CMOS jumper to reset the mobo to factory settings. My previous motherboard, an ASRock H77 Pro4/MVP, was working fine with CSM disabled with the same graphics card. Here's my system specs: AMD Ryzen 7 3700X ASRock X570 Pro4 Sapphire Nitro+ RX580 SE 2x8GB Crucial DDR4-3600 2x512GB Samsung 850 Pro Anyone known if there's any known bad UEFI interaction between my mobo and my graphics card? Thanks! |

It looks like someone else is having the same issue with AMD ASRock mobos and Sapphire video cards:
