Interface structure for connecting a plurality of graphic cards to a scalable link interface or SLI computer mother board using 16 interface slots

摘要

The interface structure is for connecting graphic cards to an SLI compatible computer mother board, which has a corresponding chip set which supports at least one PCIe x 16 interface. The structure has two PCIe x 16 sockets for the installation of two SLI compatible PCIe x 16 graphic cards to be operated in SLI mode and a PCIe x 16 socket for the installation of a graphic card to be operated in normal mode. The socket for normal mode is connected to all sixteen channels of the interface. One of the SLI mode sockets is connected to the first eight channels and the other is connected to the last eight channels of the interface.
