Not very familiar with CPU-Z, but it shows the original frequency. Eg DDR @ 400MHz runs at 200MHz. Its because it uses both trough/crest to transfer the data and hence double the speed of transfer. DDR2 @ 533MHz will have a frequency of 533/2 = 266.5MHz. So that explains the figures you are getting in CPU-Z. Hope you understood my explaination.
