Normally on boards with an LGA755 socket the FSB multiplier is determined by 3 pins/straps on the CPU called BSEL. On this board those pins on the CPU are not hooked up to the memory controller, but some GPIOs on the SuperIO are used instead. The result is that to set up the correct FSB the SuperIO needs to be configured and then the system reset. Since this reset takes a few seconds, the fans will spin up, than spin down again to resume a full boot a few seconds later.


  • The P5GC-MX/1333 might work just fine with the current code. The P5GC-MX/1333 vendor bios works fine on P5GC-MX but does not configure the SuperIO GPIO BSEL straps correctly which might indicate that it does not have those.
  • P5GC-MX/GBL ?
