I just bought a Sony laptop, model VGN-AR570. It is coming with T7100 intel processor, which has 800Mhz frontside bus. I tried to look for the chipset model on the website and called sony, but no luck at all. Does it have to be the new chipset (PM965) in order to support the 800Mhz frontside bus? I know the 945 previous version only goes to the 667 frontside bus.
