    Does PCIe 3.0 with the HD 7950 work on Linux?


      Hi. My hardware is:

      Alienware Aurora R4, which consists of:

      Intel Core i7-3930K

      Intel X79-based motherboard


      I'm running openSUSE 12.2 with Catalyst 12.8 (driver 8.982) and AMD APP SDK 2.7. In Catalyst the bus is stated to be PCI Express 2.0 x16, but AFAIK all of the hardware should be able to support PCIe 3.0. When I run the BufferBandwidth sample that comes with AMD APP SDK as "BufferBandwidth -pcie" I get a bandwidth of ~6-7 GB/s, which is consistent with PCIe 2.0 x16.


      Is it possible to get PCIe 3.0 mode working in Linux with this hardware combination?
