X1 with a x4 card



  • I am using and Intel DQ45EK as my main board. This board only has one (1) pci-e x1 slot, but I have an Intel quad port EXPI9404PTL network card that uses a x4 slot.

    I've used a pci-e ribbon cable which allows me to connect the card using a x1 to x4 and it works perfectly fine.

    This is a production firewall and I am worried this may be unstable, should I be looking at changing this?

    I know that the bandwidth is limited to ~2Gbs but I am not concerned with this.



  • As long  as the cable doesn't slip out, it should be fine.



  • I thought so.

    I think, overtime, it may slip a little so I will try and figure out some support to make sure this doesn't happen.



  • As long  as the cable doesn't slip out, it should be fine.

    A dip with a hot glue pistol should beware of the slipping of, works fine for me since years.
    And it is also very fast to dismount the cables if the glue is dried out.

    That's because pci-e is designed that way. Some motherboards have pci-e slots with no 'end'. You can fit a larger card without any problems. Some server boards have it the other way around, they only use x8 slots, but electrically most of them are x4 slots.
