Processors in an LGA1155 socket support discrete add in graphics cards via the PCI Express* 3.0
x16 graphics connector:
Supports PCI Express* GEN3 frequency of 8 GHz resulting in 8.0 Gb/s each direction (1 GB/s)
per lane. The maximum theoretical bandwidth on the interface is 16 GB/s in each direction,
simultaneously, for an aggregate of 32 GB/s when operating in x16 GEN3 mode.
Supports PCI Express* GEN2 frequency of 5 GHz resulting in 5.0 Gb/s each direction (500
MB/s) per lane. The maximum theoretical bandwidth on the interface is 8 GB/s in each
direction, simultaneously, for an aggregate of 16 GB/s when operating in x16 GEN2 mode.
Supports PCI Express* GEN1 frequency of 2.5 GHz resulting in 2.5 Gb/s each direction (250
MB/s) per lane. The maximum theoretical bandwidth on the interface is 4 GB/s in each
direction, simultaneously, for an aggregate of 8 GB/s when operating in x16 GEN1 mode.
