Running single card on SLI board

I'm using an Abit KN9 SLI board. If i'm not mistaken all SLI motherboards have both their PCIe slot run at x8 speed under SLI mode.

The problem now is i'm running my motherboard with a single graphic card. What will be my PCIe slot speed be? Will i encounter any problems running single graphic card on a SLI-enabled motherboard?

  1. no, you'll be fine.
  2. I agree.
  3. All SLi motherboards which don't have 32x in the name run sli at 8x. The 32x's are dearer because they offer full speed 16x.

    You will be fine because i read somewhere that even the 8800GTX doesn't use all the 8x bandwidth.

    that's true, i heard it as well
  5. Single PCI-Express slot runs on 16x speed. Some mobo runs 8x SLi mode and the new ones runs 16x SLi but there's not much difference when it comes to performance.
  6. I have the A8N-SLI Deluxe and it is the same:

    Run 1 card, slot runs at 16X.
    Run 2 cards, slots run at 8X.

    Although, as others have stated, 8X vs. 16X doesn't really matter yet.
