Don't worry about your bus report...it is correct.
Intel uses what is called "Quad-pumped" architecture to define their FSB speeds. This means they multiply the PHYSICAL FSB by four to get an effective rating. In other words, your FSB is actually 133MHz physical times four (133x4=533). Just as 400MHz systems are 100MHz physical x4.
3DMark reports the physical bus setting on your motherboard (if you go into the BIOS on your system, you'll notice the setting is 133, not 533).
Hope this helps!
