2X PCI-E 4.0 X16 1 to 2 Expansion Card — Gen4 PCIe-Bifurcation X8X8, 20mm Spaced Slots, CPU4P(4 Pin )

High-performance expansion card that splits a single PCI-E 4.0 X16 into two X8 links, providing full-bandwidth PCIe X16 4.0 operation using the GEN4 protocol and maintaining compatibility with gen3/gen4. Note: motherboard BIOS must support changing the PCIe operating mode to X8X8. The board is laid out for 20mm spaced slots and includes a CPU4P(4 Pin ) interface. Built with a gold-finger sinking process — gold plating thickness increased to 5U — and fitted with GEN4 connectors that feature dust plugs and snap latches for secure connections.
