Solving DX12 compatibility on ASRock B450M-HDV R4.0?
This entry-level board is a total disaster; I can't believe it crashes this hard just running Resident Evil Village. After scouring some tech forums, I found that the early BIOS versions for the ASRock B450M-HDV R4.0 have terrible support for DX12 async compute, leading to timeouts when loading large assets. I tried disabling all power-saving options in Windows, but that just pushed the board temps to 78℃ without actually fixing the crashes—a complete waste of time. I eventually risked a BIOS update to the latest stable version and did a full CMOS clear. After 10 hours of stress testing, the crashes are gone. I did realize the BIOS flash reset my RAM to 2133MHz, so I had to go back in and manually re-enable XMP to get back to 3200MHz. Board temps are now a steady 45-55℃. I exported the BIOS settings to a profile so I don't have to do this again. It's a budget board, so don't expect miracles, but it's stable now.
