re: front side bus speed Tuesday, April 26, 2005 at 1:04 pm Windows 2000 Annoyances Discussion Forum Posted by MaddMaxx (1988 messages posted) Pentium IV 2.0 is a 400mhz chip. Pentiums are "quad pumped" which means it runs on a 100mhz bus. If you got a higher series chip, the front side bus would be 133mhz and the cpu "running" at 533mhz. AMD chips are "double pumped" so a 166mhz front side bus would result in a 333mhz cpu speed. Ram runs double (DDR) the bus speed, so PC3200 would run at 400mhz if your board would provide a 200mhz bus. That said, most agree that the Ram and CPU should run at the same bus speed even if the RAM can run faster.
