 The X99 chipset uses a Direct Media Interface (DMI) 2.0 ×4 link for the connection between the processor and itself; that way, a total bandwidth of 20 Gbit/s is available to all connectivity options provided by the chipset.Up to eight PCI Express 2.0 lanes are provided by the X99 chipset, with speeds of up to 5 Gbit/s per lane and a possibility to configure these lanes into ×1, ×2 and ×4 links.Additionally, the X99 chipset supports a configurable layout of the PCI Express 3.0 lanes provided by the processor, which may be bifurcated into up to two ×16 links and one ×8 link, or into up to five ×8 links (the total number of available PCI Express 3.0 lanes depends on the used processor).
