ATX :

Asus Proart x670e Creator (pcie x8 + pcie x4 card via riser m2 to pcie x4 on m2-2 port)

Gigabyte B850 AI Top (pcie x8 + pcie x4 card via riser m2 to pcie x4 on m2-2 port)

Asus Proart x870e Creator (pcie x8 + pcie x4 card via pcie/tb4 enclosure) / do not use port m2-2)

You can even add 1 or 2 additional PCIe x4 cards if the PCIe/TB4 enclosure has multiple PCIe slots, like the Sonnet Echo Express SE IIIe.



Here are the different configurations for using two cards (x8 + x4) on the 24 PCIe CPU lanes of the AM5 platform.

Other motherboard models may support these configurations.

Consult the motherboard manuals before purchasing.
