    What is it I would like to make a dual Opteron Workstation, but what is PCI-X I see that most server mobos use it but what Cards use it? I haven't seemed to find any so far... :sigh:

    Mainly Expenise RAID cards use this slot, it Out-preforms standard PCI allowing better preformance. Alot like PCI-Express > AGP.

    AFAIK PCI-X can run between 66MHz and 133MHz. Usually used by SCSI cards/RAID cards etc, as Frank says (I think Mister Tad uses PCI-X). Most big servers use PCI-X stuff, and fancier PC's for image/video editing sometimes us it for specialist rendering cards I think. There probably won't seem to be much PCI-X stuff for sale over the web cos it's not something many people would buy for themselves, more likely to be companies. PCI-X stuff is normally pretty expensive, cos it's more often than not, quite specialist and very high performance stuff. Hope that's of some use hehe :)

    PCI-X = 64bit PCI

    That's about as close as you're ever going to get. With PCI on the way out, and the sheer size required for a motherboard to have dual CPUs, I doubt you'll see anything better than that.

    Edit: There's actually another board that does, which is a Tyan, but it's much more expensive, and more geared towards the server type...

    PCI-X is 64-bit PCI, running at 66, 133, 266 and 533MHz , the slots are PCI compatable.

    Eventually it'll disapear, replaced by 8-way PCIe, you can get some PCIe storage controllers already.

    The slots aren't PCI compatible... PCI is on the left, PCI-X is on the right. The slot is in the wrong place...

    Yes, but most PCI cards (about 95%) have two slits in the connector, one for PCI and one for PCI-X. It worth checking but it is usually is compatible.

    It's worth noting that the black slots are PCI Express x16. Just in case...

    Yes, *most* PCI cards will work in a PCI-X slot (and vice-versa) - if they'll fit, they should work. Obviously in the latter case, you take a huge bandwidth hit, but that's not really an issue in this situation.

    PCI-X is a 64bit PCI but 64bit PCI is not necessarily PCI-X

    the 33MHz 64bit pci is simply called PCI64, it gives double the bandwidth of PCI (or around 250MB/s)

    PCI-X is 64bit in speeds ranging from 66Mhz (giving 500MB/s) to 133MHz (giving around 1Gb/sec
    PCI-X 2.0 specification is availible in speeds up to 533MHz, which can theoretically provide 4GB/sec although that hasnt appeared in the flesh yet.

    PCI-X is used predominantly in servers and high-end workstations and used by storage adapters and high-eng ethernet/fibre adapters

    PCI and PCI-X cards can be used in either slot, but putting a PCI-X card in a PCI slot will obviously limit its bandwidth, much the same as putting a PCI-E graphics card in a PCI-E 1x slot

    PCI-E is a better interface than PCI-X but PCI-X will still be hanging around for years and years to come because the entire enterprise IT world is based on it and it would be ludicruously expensive (and pointless)to replace everything

    I used to use PCI-X, but got myself an Areca ARC-1220 PCI-E 8x RAID card a bit ago so have since binned the server with PCI-X :thumb:

    well the onely reason i need pci slots is for a X-fi sound card and the upcoming PhyisX processor

    I checked the pictures of the X-fi cards and they do indeed have 2 notches so the sound card would work in a pci-X slot?

    if thats the case all my problems are solved :D Thanks for all your help guys

    and i was accually eyeing this one :D a little expensive tho :wallbash:

    I have yet to come across a PCI card that hasnt worked in a PCI-X slot

    as for the board, anything from tyan or iwill using the NF4 Professional and you can't go far wrong, that should be a hell of a board :thumb:

    My PowerMac has PCI-X slots (I think):

    Theres a bog-standard PCI Wireless card in it, and it works ;)

    Ah, I hadn't ever looked hard enough at any PCI cards to realize most of them do have 2 slots. Seems I was wrong, my mistake!

    Left would work in pretty much any PCI/PCI-X Slot
    Right would only work in all PCI slots and a few PCI-X Slots.
