What does "Bifurcation Required" mean for a four-drive card?

The PA41 has no chip that splits PCIe lanes by itself. Your motherboard must divide the x16 slot into four x4 links (X4X4X4X4, or Hyper M.2 X16 on ASUS) and that option must be enabled in BIOS/UEFI.

How do I check my motherboard before buying?

Open the manual's PCIe expansion slot section and look for "PCIe bifurcation", "lane splitting", "x4x4x4x4" . Then confirm the exact slot: it must be a CPU-connected x16 slot. one that shares lanes with the GPU, often drops to x8/x4/x2.

I only see one, two or three of my four SSDs. What should I do?

In order: (1) set the slot to X4X4X4X4 in BIOS, not Auto; (2) install the latest motherboard BIOS; (3) move the card to a CPU-connected x16 slot; (4) swap SSDs between sockets to rule out a drive issue; (5) initialize and format new drives.

What speed will I get on PCIe 3.0 hardware, or with PCIe 5.0 SSDs?

Full 64Gbps per drive needs a Gen4 CPU, Gen4 slot and Gen4 SSDs. PCIe 3.0/2.0 systems run at their own speeds (about 16GB/s across a PCIe 3.0 x16 link). A Gen5 SSD runs at Gen4 x4 speed at best;
