Crucial scanner says my FSB in my HP Media Center PC is 200Mhz. My DDR SDRAM is 400MHz though. Does this mean that my FSB is bottlenecking my system because it's not goin fast enough for the memory or am I missing something? Any feedback would be appreciated.

DDR is Double Data Rate. Basically it runs twice as fast because it does 2 operations where the old SDRAM did one. So even though the bus runs at 200 Mhz the effective clock speed of the ram is 400 because it doubles its operations in every cycle
