Above statement applies to real world of technology. You wont find a HPaq,
Dell or IBM server that will allow you to monkey with that. On the
otherhand... for consumers:
There are technical deviations from this, like VIA Appolo Pro133A chipsets
allowing you to run PC133 memory at 133Mhz while you have a 100Mhz FSB
processor.... My KT333 chipset on my Abit KX7 allows me to have a 200/233
CHIP with 333 DDR.
My KT400 chipset allows me to run my memory out of sync with the CPU bus,
but only at speeds faster than the CPU bus.
But DDR and RAMBUS are muliples of the FSB on the board. Most current CPU's
"pump" the FSB to give you the internal clock of the CPU. So, an 800Mhz FSB
P4 is really a Quad 200Mhz FSB. AMD's are doubled (thanks to the Alpha EV
bus architecture, 333Mhz Bartons are (2x 133 FSB).. and on and on.
