what board is this. most of them the second pcie x16 physical slot is a 2.0 slot.

id be happy with a 4x 3.0 lane for the raid card, but there are far too many boards that just flat out disable the second pci-e x16 (physical) slot when use use an nvme in the m1 slot. The chief offenders here are all the asrock 350, 450 series boards. the x series boards generally do behave better, but also, pricier. a bifurcated 8x/8x would be the best, but that definitely requires an x series.

Looking for a board to support the following: 1) A pcie 3.0 GTX1070 or other modern gpu 2) A pcie 3.0 x8 RAID card 3) full speed x4 Nvme capability Ryzen has enough lanes to do this, but i am having trouble finding a board that has this pci-e distribution. On most, the second x16 physical slot is a x4 electrical slot, hardwired. On some, the second x16 physical slot is disabled when you use the m.2 slot. I dont need any sata ports and i dont need a second m.2 slot. Many boards even disable the second pci-e entirely if you use the nvme m1 slot
