A quick Google search says it should if the z400 has 6 memory slots and to make sure the bios is up to date. The posts I looked up mentioned making sure you have proper cooling, depending on the heatsink it may need a little more cooling power? Though the x5670 is 95w not 130w.
It would not be over clockable as it is not unlocked like a W chip would be.
Though I can't guarantee any of this...
