Well, the time has come to upgrade my BX6-r2/Celeron 300A(450) combo. If I make sure that I download the latest BIOS, could I run one of those illustrious PIII 700E or Celeron 566 processors in my BX6-r2? And if so, will I be able to overclock the FSB to 133? I can't find my original manual or any other source of info on this, so you guys are my last hope. =) Help!
