3.5 PCI-Express connectors
The KTG41 supports one 16-lane (x16) PCI Express port and one 4-lane PCI Express (x16) port.
The 16-lane (x16) PCI Express
can be used for external PCI Express graphics card. It is located nearest
the CPU.
The PCI Express port is compliant to the PCI Express Base Specification revision 1.1. The x16 port operates
at a frequency of 2.5 Gbit/s on each lane while employing 8b/10b encoding; the port supports a maximum
theoretical bandwidth of 40 Gbit/s in each direction.
The PCI Express (x16) interface is multiplexed with the SDVO ports.
The 4-lane (x4) PCI Express
port is mechanically an x16 port and electrically an x4 port. It is located
farthest away from CPU.
