I strongly advise against this board and boards from ASROCK. Good configuration: 8 layers, 4 M.2, powerful power supply system. The board kills processors. This board killed my 9600x processor after 8 months of use, warranty was denied. The BIOS is inconvenient.  Evgeniy Yaroshenko: use ASRock B850 Pro RS few months |
