   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

	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
