3.5 PCI-Express connectors
The KTQ45 board supports one 16-lane (x16) PCI Express port and one 4-lane PCI Express (x16) port.
The 16-lane (x16) PCI Express 2.0 port can be used for external PCI Express graphics card. It is located
nearest the CPU.
Supports PCI Express GEN1 frequency of 1.25 GHz (supports 2.5 Gbit/s in each direction, 500 MB/s totally).
Maximum theoretical bandwidth using 16 lanes is 8 GB/s.
Supports PCI Express GEN2 frequency of 2.5 GHz (supports 5.0 Gbit/s in each direction, 1000 MB/s totally).
Maximum theoretical bandwidth using 16 lanes is 16 GB/s.
The PCI Express (x16) interface is multiplexed with the SDVO ports.
The 4-lane (x4) PCI Express 1.1 port is mechanically a x16 port and electrically a x4 port. It is located
farthest away from CPU.
