    PCIe 2.0 x16 slot only operating at 2.5 GT/s

      I had a Radeon 4870X2 that was recognized in BIOS as having a Link Speed of 5.0 GT/s in the PCIe 2.0 x16 slot.

       

      I upgraded to a gtx 580 SC in the same slot and the link speed is reported as 2.5 GT/s.

       

      How do I change this? Why is it not reporting the same Link Speed? Will this affect performance?

       

      GPU-Z recognizes it as PCIe v2.0 x16 using x16, so am I fine? I haven't had a chance to run benchmarks yet. I'm posting this at work, so I will when I get home.

       

      I have updated the BIOS recently and it didn't help.
