Note: The number of PCIe slots and the slot naming can differ depending on the PCIe devices connected to your motherboard.
Bifurcation
This feature is CPU-dependent. Use this feature to configure the PCIe Bifurcation setting for the PCIe port you specified. The options are Auto, x4x4x4x4, x4x4x8, x8x4x4, x8x8, and x16.
Note: After you’ve enabled VMD in the BIOS on a PCIe slot, this PCIe slot will be dedicated for VMD use only, and it will no longer support any PCIe device. To re-activate this slot for PCIe use, disable VMD in the BIOS.
Intel VMD Technology
When this feature is set to Enabled, VMD support will be automatically enabled when a VROC key is detected by the BIOS. The options are Disabled and Enabled.
