Bus Clock speed on Westmere Mac Pro

I have a new 6x 3.33GHz Mac Pro.
It uses 1333MHz memory.

Using Digiloyd memory Tester it reports a bus speed of only 1073MHz which is close enough to what I'd expect for 1066MHz memory.

Shouldn't the bus speed for this system be 1333MHz or thereabouts?

Can anyone else check what their systems report, Nehalem or Westmere?

This suggests the memory is not running at its rated (advertised) speed.
