ASUS A8N-SLI: Where's the PCI Slots???

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

Looking to purchase ASUS A8N-SLI and there's only 3 PCI slots. But! In
place of two of the places where there would usually be a PCI slot is a
PCI Express Slot. Now I realize PCI Express is the new graphic
interface designed to replace AGP. But what the heck is this new PCI
Express X 16??? Is this supposed to be a new interface for devices like
ethernet, sound card and modem? I have never seen a network card or any
device (other than graphics cards) use PCI Express interface.

    It is for a second graphics card so that you can run 2 cards,but beware if
    you go this route you are supposed to buy 2 cards that are matched (made
    together at the same time) its only my opinion but after the problems that
    my son had with one of these mobo's I would not go there again..hope this
    helps..

    Ethernet, firewire and on-board sound are built into modern
    motherboards. If you really must still use a bunch of legacy cards,
    get the non-SLI version ( single PCI X16 slot) of a PCIe board.
    Generally they have up to 4 normal PCI slots. And yes, the x1
    and X4 PCIe slots that are on most of the boards are currently
    under-utilized.

    Seems as if you have a lot more reading (and understanding) to do
    on modern PC configurations before plunging into any such
    purchase.

    Consider what you really want to do with your computer over the
    next couple of years--- then look at the software that will achieve
    that objective --- then finally the required hardware --- in that
    order.Climbing on to any hardware bandwagon like SLI regardless of
    your real needs is a recipe for disappointment and poorly-spent
    money.

    I assume you're talking about the PCI Express x1 slots, not the x16
    slots.. Eventually all devices that are using regular PCI slots now will
    likely migrate to those slots. There is not much using them right now,
    though PCI-E x1 network cards do exist..

    Hello Robert Hancock, yes I did some more research and I realized that
    I was actually talking about the PCI Express X1 slot, not the X16 slot.
    I have been doing searches for network cards, modem cards, and sound
    cards that utilize PCI Express X1 and I can't find any.

    It is very hard for me to believe that as you said, "eventually all
    devices that are using regular PCI slots now will likely migrate to
    those slots." Usually when you see a migration as you have described,
    you hear about things on sites such as Tom's hardware. However, if you
    goto Tom's hardware the only thing you see is information about PCI
    Express X16. There is no info regarding PCI Express X1.

    TDP - you missed my point. I am well aware of PCI Express and it's use
    for graphics cards and yes I'm aware that the motherboard I mentioned
    about is SLI capable. I'm not interested in discussing PCI Express and
    it's use for graphics cards. I did make the mistake of saying PCI
    Express X16 instead of PCI Express X1 so I was confusing in that
    regard, sorry.

    John Lewis - I just used the motherboard above as an example. I would
    likely not buy the Asus A8N. I know for a fact that I will not use the
    SLI as the performance gain (IMHO) is minimal and not cost effective.
    If I did buy a motherboard it would probably not have all the onboard
    stuff on it (it would be a basic board) due to the fact that I have my
    own high performance sound card, ethernet, modem, and usb ports. It's
    just alarming to see some ASUS motherboards with as many as 4 or 5 PCI
    X1 slots and I have yet to find one peripheral that uses those slots.

    I spent last Friday at Fry's electronics and I was looking at the Asus
    boards and I found little PCI X1 slots located in little spots all over
    the board (not just in the traditional PCI slot spaces but) in
    different places and I was wondering what in the devil all those slots
    were used for. I counted 5 PCI X1 slots on one motherboard (I don't
    remember which board). What a waste of space.

    Why Belkin?? How come we can't get reputable companies like Audigy,

    The PCI-x bus is new. There weren't many PCI cards available when it first

    First one I found on Google.

    Seriously, PCI Express just hasn't been out that long. Same for
    Windows XP64. Finding drivers for it is a pain right now. A year from
    now there'll be more drivers just like there'll be more PCI Express
    cards. Heck, I saw an LSI Logic SCSI card that was PCI Express that
    took an X8 slot. Now, what motherboard are you going to stick that in?
    <rhetorical question>

    There used to be a bunch of motherboards that had that stupid ACR
    slot. Whoever used that?

    OTOH, I've got a lot of ISA cards with no slots to put them in.

    Just wait until motherboards don't even use copper contacts for logic
    connections. They'll be using fiber optic ~gigahertz busses.

    Personally, I'm just going to hang on to this old fashioned Abit AV8
    AGP board for a while. I figure an upgrade to the last, fastest AGP
    graphics card they'll make and an AMD64 X2 4800+ processor will keep me
    going for a couple of years.

    But how many PCI ( non-e) slots do you now really need on a modern
    motherboard, considering the integrated peripherals ? And the PCIe x1
    and x4 slots will be usefully applied once PCIe is the norm and the
    current fixation with video cards has died down.

    BTW, the spare x16 slot on a SLI motherboard is likely to be used
    by a future high-performance peripheral, such as a real-time video
    editor or a physics processor for gaming ( in x8/x8 mode on the
    current SLI boards, and in x16/x16 mode on the upcoming motherboards
    using the new nForce4 SLI X16 chip-set. )

    There are many SLI motherboards out there that still have the second
    video slot empty, and it probably will continue to be empty for quite
    a while, particularly with the advent of the high-performance
    single-socket PCIe video cards, 7800GTX, 7800GT and the upcoming
    Ati X1800. nVidia has now shipped almost 2 million SLI
    chip-sets.......

    The problem is, you don't have any appreciation for exactly how
    high tech PCI-Express really is. Both it and SATA have taken
    a big leap, compared to the technologies they replace.

    The PCI Express signals work at 2.5 gigabits/sec. Up to a few years
    ago, you would only find those signals inside fiber optic networking
    equipment, where the circuit packs cost $100,000 a piece. Or
    inside test instruments costing $50,000 and upwards.

    The practical upper limit for signal transmission on an FR4 PCB
    material, is about 3Gb/sec. I have not been keeping up on the
    technology, but perhaps a signal can be pushed 18" at that speed,
    without the use of more complicated I/O pad design (pre-emphasis ?).
    FR4 PCB material is lossy, especially at high frequencies. No
    motherboard, or add-in card manufacturer, wants to use exotic
    dielectrics for the printed circuit material.

    For a new technology to be successful, it must be easily applied
    by humble ordinary engineers. If only a hundred specialists can
    make the technology, it will never be wide spread.

    At the silicon end, up until a few years ago, maybe you would
    find LVDS I/O pads operating at 622Mb/sec or with a few companies,
    perhaps twice that I/O rate (1.2Gb/sec). There really weren't a lot
    of good reasons to make I/O pads that work faster than that (with
    the exception of telecom and fiber optics customers and the like,
    and the business they generate is minimal).

    What does that mean to your average company ? First, you need
    someone who knows how to route a cheap FR4 PCB with the 2.5Gb/sec
    signals. Those guys don't grow on trees. Next, you have to use the
    latest silicon technology (90nm perhaps), to get the 2.5Gb/sec
    I/O pad to drive the signals. If you are doing analog signal
    processing, perhaps the analog functions plus the digital functions
    you need, are not available in the same cell library - this
    stuff all has to live on the same chip, after all.

    In other words, you need deep pockets, to fund the new lab equipment
    (measure eye opening of PCI Express I/O signals), to find the
    silicon tech that supports both your applications circuits and
    also the PCI Express I/O.

    And, not all add-in card areas seem to have continued interest
    in hardware development. I don't expect to see cheap PCI Express
    SCSI controllers for example. There is this RAID controller on
    Newegg, but I wouldn't expect to find a non-RAID controller
    any time soon, nor one at a decent price.

    LSI Logic LSI00008 PCI Express x8 SCSI RAID ($620)
    http://www.newegg.com/Product/Product.asp?Item=N82E16816118027

    SATA is the future, and there should be more SATA cards than SCSI.

    Areca ARC-1220 PCI-Express x8 SATA Controller Card RAID ($695)
    http://www.newegg.com/Product/Product.asp?Item=N82E16816131004

    With the old 32 bit PCI, the signals work at 33Mb/sec or 66Mb/sec,
    versus PCI Express 2500Mb/sec. That is a factor of 38 faster
    in the latter case. It will take time for the necessary tools
    and information to spread, before any garage operation can
    make PCI Express hardware.

    The part that gets real interesting is not the pci slots or the pci-e
    slots, but the fact that so many motherboards and periphials need a
    slot opening to offer the external connectors, in one case I needed
    four additional empty slots to mount all the connectors to the slot
    covers and now I see that some of the water cooler people are mounting
    external radiators and routing the hoses thru an empty slot cover,
    eventually you end up with every slot cover taken and no actual room
    for pci or pci-e cards

    While I was puting my new PC together I got stuck in with drills and
    files and mounted the COM, Games and 4 extra USB connectors so that my
    PCI and PCI-E slots were free.

    I am surprized the case manufacturers do not provide knockouts for
    easy fitting of all the extra connectors provided with modern
    motherboards.
