PCI-X compatability

***tetraburmium*** · April 3rd, 2005

If I have a mobo with a number of PCI-X 64bit slots (either 100 or 133 MHz) can I put in standard PCI boards, or are they restricted to only PCI-X 64bit boards.
For example would an Audigy 2 Card go in one of these slots.
Thanks guys,

I think so, they would not make a new type of socket if there is no cards that use it

I think pci-x is normal PCI

I thought PCI-X was the same as PCI-E...

PCI-X != PCIe.

PCI-X is the "PCI-Extended" standard.
They're white (just like any other PCI slot), but about twice as long.
They're 64-bit, but the card in them need not be.
64-bit PCI clock speed is 33MHz.
PCI-X clock speeds are: 66MHz, 100MHz, 133MHz, 266MHz, and 533MHz.
Yes, standard-length 32-bit PCI cards will run in them, if they're designed to operate at the proper voltage: the 64-bit/33MHz PCI slot operates at +5V. All PCI-X slots operate at +3.3V. Fortunately, all slots are keyed such that you can't screw it up: if the card fits, it should work fine.

Great, time to check manufacturers specs and I should be ok.
Thanks all.
