Yes, you can use a card that uses a smaller number of PCIe channels in a 
larger slot - the reverse is not true of course. The card won't be any 
faster than if it were plugged into its native slot but it works correctly.

This means you can use a x1 card in a x1, x4, x8 or x16 slot, a x4 card 
in a x4, x8, or x16 slot and so forth.
