Nvidia has released a patch that allows video cards from the 6xx series, with a Kepler gpu on board, on more platforms the derdegeneratie-pci express interface can use. Previously supported only 1155 boards that interface.
The motherboards from different manufacturers that Intel’s latest chipset, the Series 7 Express chipset, equipped, support pci express 3.0 interfaces. Also a lot of Series 6 boards, originally designed for Sandy Bridge processors, but also equipped with a lga1155 socket to support the higher bandwidth that pci express 3.0 offers. The latest video cards from both AMD as Nvidia can with the extra bandwidth to handle. Nvidia pulled support on the high-end platform based on Sandy Bridge E-processors, however, due to lack of formal certification for the pci express 3.0 interface.
With its latest patch has Nvidia the pci express 3.0 support on the X79 platform, also known as the Sandy Bridge-E HEDT platform, made possible. The patch is compatible with the newest graphic cards from the Kepler series including the GTX 670 and GTX 680. That will be after a reboot forced in pci express 3.0 mode to rotate, so that the total available bandwidth of a lane of 8GT/s can be used. Incidentally, would almost exclusively sli setups with cards in a x8 slot to be inserted to take advantage of the extra bandwidth. A x16 slot with pci express 2.0 interface provides enough bandwidth for the Kepler cards.
