4.5 PCI-Express Connectors
The KT965 boards contains one 16-lane (x16) PCI Express port intended for an external PCI Express
graphics card. 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 Gb/s on each lane while employing 8b/10b encoding; the port
supports a maximum theoretical bandwidth of 40 Gb/s in each direction. The PCI Express (x16) interface is
multiplexed with the SDVO ports.
Depending on the board variant the KT965 boards further supports one 4-lane (x4) PCI Express port.
The KT965/Flex supports one 16-lane (x16) PCI Express port and one 4-lane PCI Express (x16) port.
The KT965/ATXP supports one 16-lane (x16) PCI Express port.
The KT965/ATXE supports one 16-lane (x16) PCI Express port and one 4-lane PCI Express (x16) port.
4.5.1 PCI-Express x16/ SDVO connector
The KT965 boards supports one 16-lane (x16) PCI Express port for external PCI Express based graphics
