Question about MSI B450I Gaming Plus AC

Hi Morrow

Bought the same mobo for my ryzen 3700x stream build and unfortunately was on the old bios at the time. Had to use a second gen CPU from Ryzen to upgrade. If you don't have one, it might be a bit difficult.

I think not. That's why MSI has brought out the MAX boards with larger bios memory. See MSI B450-A PRO MAX (AM4, AMD B450, ATX)
Better ask Digitec directly
