    I want to get a Bluetooth dongle but I don't really want to put in on the back of the PC, rather I would like to buy a simple USB expansion card - this one.

    The trouble is that the two free plain PCI slots I have on my PC are unusable because one for them is completely hidden under my GTX-560Ti card and the PCI2 slot is so close that if I used a card it would block the fans of the card.

    All I have left free are:

    1 x PCIe 2.0 x16_2 slot (white, at x16 link)
    1 x PCIe 2.0 x16_3 slot (black, at max x8 link)

    Could I use any of these? If so which one would be best?

    The reason I want do do it this way is so that I can put the Bluetooth dongle on the internal USB slot on the expansion card so it will have a clear line of transmission through the side of my case which contains a window and open-mesh for ventilation.

    Any advice would be appreciated, even if someone has a dongle like this and even when connected to the rear of the PC knows it works fine, negating the need for me to buy the USB card.

    Thanks

    Hello,

    Firstly you cannot use a PCI card in a PCIe slot. You can however buy PCIe USB cards (we sell them)

    Secondly, you don't need one. Bluetooth doesn't require line of sight and has a range of at least a few metres. So you should be fine. I've used USB bluetooth dongles from the other side of a room with one in the rear of a PC.

    Thanks Chris for a fast response and great advice.
    I'll just send for the dongle then.
    I just had a look around Lindy and saw this.

    If I got one of these could I get full read/write speeds from a USB 3.0 device?
    I assume this could go on the PCIe 2.0 x16_3 slot (black, at max x8 link) that I have spare as it is the one with the most room around it.

    His Chris, yeah it was the

    2 Port USB 3.0 Card, PCIe
    2 Port USB 3.0 Card, PCIe | USB Cards | USB & FireWire | LINDY UK
    us Type: PCI Express (x1)

    I will get a hold of my mate, he might be interested in one of these as well. Time for me to upgrade to USB 3 and get some external drive and flash to replace the 2's I have now.

    I just bought one of these for the the simple reason that there was reduction in price and a free delivery offer on a USB 3.0 Portable HDD on which I could piggyback this card for free delivery as well.

    I know from previous answers that it will go into one of the two slots available below, but please could you let me know, anyone, which would be the most suitable? Maybe the max x8 link one?

    1 x PCIe 2.0 x16_2 slot (white, at x16 link)
    1 x PCIe 2.0 x16_3 slot (black, at max x8 link)

    Check your motherboard manual to see if using either of them reduces the speed of your graphics card slot.

    Hi Endless waves or anyone else.

    My setup as far as cards are concerned is this:
    I have a Soundblaster X-Fi Extreme Audio Card on the PCI Express x4_1 slot (the tiny slot near the CPU).
    My Nvidia GTX560Ti is in the PCIe 2.0 x16_1 slot (blue) slot.

    This is what the Mobo manual states:

    In single VGA card mode, use first the PCIe 2.0 x16_1 slot (blue) for a PCI Express x16 graphics card to get better performance.

    In CrossFireX™ or SLI™ mode, use the PCIe 2.0 x16_1 (blue) and PCIe 2.0 x16_2 (white) slots for PCI Express x16 graphics cards to get better performance.

    Use the three PCIe 2.0 x16 slots for 3-Way CrossFireX™ mode.

    (**)
    If you install a PCIe x16 graphics card on to the PCIe x16_1 slot, a PCIe device with a bandwidth faster than x8 link to the PCIe x16_2 slot, and a PCIe device with a bandwidth slower than x4 link to the PCIe x16_3 slot, the three PCIe x16 slots will work at x16, x16, x1 link as the default.

    If you install a PCIe x16 graphics card on to the PCIe x16_1 slot, a PCIe device with a bandwidth slower than x8 link to the PCIe x16_2 slot, and a PCIe device with a bandwidth faster than x4 link to the PCIe x16_3 slot, the three PCIe x16 slots will work at x16, x8, x8 link as the default.

    You may manually reassign the link width of PCIe x16_2 and PCIe x16_3 1 slots in BIOS settings. See page 3-28 for details.

    Does this make any sense to anyone? I cannot find anything saying that my graphics card will slow down here but it seems to me that the 4th paragraph (**) is the one that concerns me. As far as I know the USB 3.0 card is x1, and only the blue PCIe x16_1 slot is used by the graphics card. The remaining two slots are clear, the white one being a x16 at x16 link and the black one being a x16 at max of x8 link.

    I am pretty sure that the USB 3.0 card is a x1 so my assumption is that I can put the USB 3.0 card into the black one - x16 at max of x8 link.

    Is this correct and will it slow down my graphics card?

    Yeah, black one is the best choice.
