Hi Asrock Team, I'm switching from a Gigabyte Board to the Asrock X399 Gaming 6 at the moment because my Gigabyte board died and had one of the worst software support ever from Gigabyte. ;) I have two x16 PCIe Cards + 2x NVME x4 Devices running on the board. Is there any internal documentation of the pcie lane assignment to the internal Threadripper DIEs? This is important when you want to build a NVME Raid or/and making sure that the GPUs are on the same DIE for Performance reasons. Thanks! Like this one from Gigabyte?
