Default X1, X4, cards and sockets, are they interchangable?

Clearly it is not possible to plug a X4 or X16 card into an X1 socket, but is it possible to plug a smaller card into a larger socket?
ie. plug an X1 card into a X4 or X16 socket?

Cheers.

Yes you can, PCIe is compatable as long as the co-efficent of the x is lower on the card then the co-efficent of x on the slot you wish to use. Thus a 1x card would fit in a 1x, 4x, 8x, or 16x slot.

A 1x slot will fit only 1x cards
A 4x slot will fit only 1x, and 4x cards
A 8x Slot will fit only 1x, 4x, and 8x cards
A 16x slot will fit only 1x, 4x, 8x, and 16x cards
