Good day,
Does the X570S PG Riptide support Bifurcation? If not, are there any other X570S boards that do?
Many thanks for reading my question!
Have a wonderful day,
Mike

The PCIE1 x16 slot is connected to the CPU and provides 16 lanes, depending on the CPU

PCIE4 provides only 4 lanes
PCIE6 onl;y 2 lanes, both are connected to the X570 chipset.
The Bifurcation is a difficult question, becasue in the BIOS under advanced AMD PBS, you can find the options that enable to divide a slot into 2x 8, or 4x 4 lanes, but this is part of the Agesa code that AMD writes, it is not something ASRock can define
