Question: 1. Would a single Graphics card x16 become reduced to X8 using 1 or 2 of these Ultra M.2 Slots(x4)? 2. If running in x8 PCIe would the GPU take a performance hit? Currently, I'm using a 780 on a PCIe 2.0 x 16 slot which is the same thing. I'm looking real hard at the http://www.newegg.com/Product/Product.aspx?Item=N82E16813157627&cm_re=asrock_extreme_7-_-13-157-627-_-Product" rel="nofollow - |

| From http://www.pugetsystems.com/labs/articles/Impact-of-PCI-E-Speed-on-Gaming-Performance-518/article" rel="nofollow - this article , it would appear that even if the GPU(NVidia) is running at X8 it doesn't matter. |

if you are using the motherboard m.2 slot, usually PCIe slot 5 is disabled ( the last slot ). it depends on the board, it works that way for the extreme4/3.1 I have. the other slots can still run at 16x. you can purchase PCIe v3 cards and use up one of your PCE v3 slots for two m.2 cards but they don't support any kind of motherboard raid of them, you just have two really fast drives. not all boards support booting from the M.2 , the extreme4/3.1 does not support it as of today while the extreme4 does... go figure. |
