Some references: http://www.lowendmac.com/tech/pci.shtml http://www.serverworks.com/technology/pdf/PCI-X_2-0_WhitePaper.pdf Speed Mismatch Compatibility All speed generations of PCI are interoperable. For example, a 33MHz adapter card can plug into a 66MHz slot, a PCI-X 133 slot, or even a PCI-X 533 slot. If the card can't meet the performance of the slot, the slot frequency is throttled down to meet the maximum frequency of the card. In this example, since the card is capable of operating at 33MHz, the slot will change its frequency to 33MHz to match the speed of the card. The converse is also true; a higher performance card will also adjust its frequency to match the maximum performance of a slower slot, maintaining complete forward and backward compatibility.
