    PCIe Gen2 x16 into PCIe Gen3 x8

    OverLord, This is a riser containing two physical x16 slots. The riser spec says that you can either use a Gen3 x16 card in one of the slots or 2 Gen3 x8 cards in both slots (x8 electrical, x16 mechanical). Now since the bandwidth for Gen3 is double that of Gen2, I'd imagine you should be able...

    PCIe Gen2 x16 into PCIe Gen3 x8

    Shintai, why? The amount of bandwidth required for a Gen2 x16 is equal to the amount required for Gen3 x8

    PCIe Gen2 x16 into PCIe Gen3 x8

    Thanks for the quick reply! So you're saying that a Gen2 x16 card will operate at full bandwidth if plugged into a Gen3 x8 slot?

    PCIe Gen2 x16 into PCIe Gen3 x8

    It's a dual socket server motherboard containing the Patsburgh (C600 -A) chipset and two E5-2600 series processors. I believe Ivy Bridge for server boards does not come out until 2013. Shintai, what do you mean by "an electrical PCIe 3.0 x8 would downgrade to PCIe 2.0 x8. Not x16"? If it needs...

    PCIe Gen2 x16 into PCIe Gen3 x8

    I was wondering if placing a PCIe Gen2 x16 card in a PCIe Gen3 x8 slot would work? I have a PCIe Gen3 motherboard which can take up to 4 PCIe Gen3 x16 cards or 8 PCIe Gen3 x8 cards. Since the bandwidth is doubled for PCIe Gen3 compared to Gen2 (1GB/s compared to 500MB/s), would I be able to...
