FSB speed question

can someone explain the difference between my fsb speed and rated fsb please as on cpu-z.



I understand that core speed = bus speed x multiplier, but where does rated fsb come in and how does it relate to the other previously mentioned?

  1. It implies that my quad pumped has been oc'd??
  2. The bus speed as listed is actually the speed of the reference clock, the clock speed is the multiplier times the reference clock, and the FSB transfer 4 chunks of data per cycle of the reference clock so its like a standard 1 chunk per cycle bus going 4 times the speed of the reference clock. It shoudl really be listed as MT/s(megatransfers per second) rather than MHz.

    Bus speed=133MHz
    FSB=Bus speed x 4 (because it is quad pumped)=133x4=533MHz
    Your CPU=Bus speed x CPU multiplier=133x6=800MHz

    Makes sense?
  4. Thanks guys that helps!!
    I was going round in circles and confusing myself, couldnt work out the X4 and X6 bit and come up with those numbers!
  5. No problem!
