Will a PCI-X card work in a PCI slot?

[Olimain]

I have been offered a BlackMagic Decklink PCI-X card by a friend however my motherboard only has PCIe and PCI slots. Would the PCI-X work in a normal PCI slot? I can't seem to find a definitive answer anywhere.

Thanks

Do you mean the card you're being offered is PCI-E?

[Olimain]

No, PCI-X

So if it's PCI-X you're out of luck as it won't fit PCI or PCI-E Sorry

PCI-X is generally backward-compatible with most cards based on the PCI 2.x[1] or later standard, meaning that, a PCI-X card can be installed in a PCI slot, provided it has the correct voltage keying for the slot and (if inserting into a 32-bit slot) nothing obstructs the overhanging part of the edge connector.

So in other words, 'it depends'. Ask the manufacturer of the Add-in Card for an assurance that the card is backwards compat. with PCI 2.x before buying. Or, you could just try plugging the card into your PCI slot to see if it mechanically fits. Obviously don't try to force it.

I'm sure some PCI-X cards do fit PCI slots at least the SAS one i have does
you get a reduced bus speed
