I have a B450 Pro4 motherboard (bios version 3.50), Ryzen 2200G, no discrete GPU, 16GB FlareX memory 3200C14(2x8 GB, manually timed at 3200 with fast settings), 500 GB SSD, Windows 10 Home 1903. I want to allocate 4 GB or more of memory for the Vega 8 graphics. Per the FAQ, I am supposed to disable CSM. When I disable CSM, save and quit, I get the ASRock splash screen, and then I'm back into bios, no matter how many times I save and quit. Once I revert CSM back to enable, I'm able to boot into Windows. Any ideas what I am doing wrong?

Good morning @Vulpie05,
Could by any change you are using MBR and hence not able to use CSM off, see https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/switch-from-legacy-mbr-disk-to-gpt-disk-with-windows-10 |
